vb.net Deserialize JSON output - YouTube API (With somewhat of a working example included)
Hello All;
I had another thread open, but I closed it out and started this one.
With a working example, but need to get all the values, instead of a single value duplicated for the number of records returned.
Here is the test JSON that I am using.
OR (You can use the code below if you have a YouTube API to add to the end of the URL String.)
This is the working code that returns duplicate values.
Could someone please assist me in deserialize this?
Thank You

This is the working code that returns duplicate values.

For Each Row In jo("items")

Who is Participating?
it seems that you're working well in progress :)
With a working example, but need to get all the values, instead of a single value duplicated for the number of records returned.what info you wish to get here? or you want to deserialize the whole JSON string to object?
It's best if you just define objects and deserialize into those objects; e.g. -

@Ryan
It is a two step process.
The example that I provided, cannot be used as it is PRIVATE.
Step #1: [Get the videoId]
Process playlist, and get all VideoId's associated with that list.
Step #2: [Get the information]
Use the videoId to get the information about the Video.
(This is from one of my Video's as an Example)
I can then parse this out to work in my news site.
The way the OLD API worked, I was some-what able to do this in one step.
However, that is no longer the case with the new API.

I have played around with code similar to yours, but never found out how to properly use it.
I will take a deeper look at yours, and see if I can make it work the way I need it to.

Question about your code.
I am messing around inside of the [ return string.format()]
I have selected the items that I want to keep and discarded the ones that I do not need.
To insert these values into a database. Would I place the database "INSERT" statement inside of the [Class Snippet]
(or)
Would it be placed after the DIM Playlist?

To insert or update the values in a database, it actually makes more sense to use AddWithValue.
So this would look something like (untested):

Thank you, -saige-.
However, this would need to be in a single INSERT statement.
I will play around with what you have provided and see if I can come up with something, using your code as a building block.
This should be fun.

OK, I am trying to learn what you have done with the code, so I can use it to do other pages with, without having to ask a bunch of questions later on. Also, for those that come in here, they will also be able to learn from this as well.
Let me know if this is correct?
Kind: {1} = The 1 means there is only 1 object.
Items: {5} = There are 5 objects and the end of the first nodes.
The items are:
[ = 1
{ = 2
kind = 3
etag = 4
id = 5
And then "snippet" starts its own Node set.
snippet
{ = 1
publishedAt = 2
channelId = 3
title = 4
description = 5
And then Thumbnail has its own Node set, and so on...
This has me a little off, on what it means.
> {0}{1}{1}{1}VideoId: {3}
Is this correct, or am I off by a long shot?

I LOVE the last solution that you provided.
It works SO Well!!!
It is less coding than the original, and much easier to maintain than the first code sample you provided.
I am Glad that I asked the question with the misunderstanding of the way you coded it.
As if it was not for my misunderstanding, of what you originally proposed, you would not have provided this excellent code example and explanation.
I am still not 100% on top of what you did in the first example, with all the numbers.
Though I am learning.
The last code you provided is much easier to work with.
Not certain if I will be able to do everything that I want with it, however. I will cross that bridge when I get there.
Thank you so much -saige- you have really helped me out a LOT.

You know how you have your Favorites list on YouTube?
That is the ones that are causing the issues.
So, it is caused by a record that does not exist.
In this case, it is my favorites.
SO. The question is.
How to bypass that list.
This the is Favorites.

You have to check each property to see if it is nothing before trying to access the properties underneath. Newtonsoft will create a new instance of missing properties but if the internal Standard property is null (or nothing) then the Url will not exist; e.g. -
Produces the following output -
That being said, you could always implement backing fields so that default values are set; e.g. -
Personally, I would use the backing field method as you can put validators on your setter. In either case, with the above changes we can get rid of our Null checking and just print out as before.
Proof of concept -
Now produces the following output -

Produces the following output -
That being said, you could always implement backing fields so that default values are set; e.g. -
Class PlayList
Dim _kind As String = String.Empty
Dim _eTag As String = String.Empty
Dim _nextPageToken As String = String.Empty
Dim _pageInfo As PageInfo = New PageInfo()
Dim _items As List(Of Item) = New List(Of Item)()
Property Kind() As String
Get
Return _kind

Set
_kind = Value

End Property
Property ETag() As String
Get
Return _eTag
End Get
Set
_eTag = Value
End Set
End Property
Property NextPageToken() As String

Return _nextPageToken
End Get
Set
_nextPageToken = Value

End Property

Public Property NextPageToken() As String = String.Empty

Personally, I would use the backing field method as you can put validators on your setter. In either case, with the above changes we can get rid of our Null checking and just print out as before.

Now produces the following output -
-saige-
I implemented the first one. The check for NULL.
I was getting 83 records inserted, but now only 80.
(Need to check my playlist and see if it is 80 or 82.
As I know the 83 one was the [Favorites]
So, what happened to the other 2?
And the playlist is 83, with [Favorites] being the 83rd one.
The others have a condition that should not exist. See below.)
I like the concept behind the last method, (untested on my end right now)
See, I do not want to enter anything into the database if it does not have the Thumbnail URL assigned to it.
that means that it is not a part of what the Producer has uploaded.
I did find an issue.
Though, this is something that I will most likely have to find out elsewhere unless you have experienced it, and can possibly give me some information on. (Let me know if I need to open another thread for this one.)
The following is Visual Studio and Sony Vegas. (Visual Studio did not get added to the database)
On Visual Studio, it does have a Thumbnail assigned to it, but it seems to be all messed up in its coding.
"channelTitle": "Dark Effects Studios"
Is NOT supposed to be where it is at.
All the other entries are located like the Sony Vegas is.
Any idea's on what might have caused this to happen?

Assuming that what you are showing me is from the youtube api, you would have to approach youtube to determine the reason for the apparent mixup.
As for the reason the null check produced fewer results. This is what the null check is supposed to do, if you find that you have null values then unless your datafield in the database supports a null, you don't provide data; by the same rights, you don't try to read properties of a null property.

Understand the NULL process.
Which is what showed me the issue with YouTube's JSON feed being incorrect in some of the values.
And the script here is what is stopping the values from being inserted into the database.
As there is NO thumbnail URL in the list.
Thanks -saige-
I am going to work on the other scripts now, using your concepts shown here.
And find a good forum to question about the misinformation on the YT JSON output.

OK. Found out the issue.
I was using the [standard] for the image.
And it seems that it does not always show up.
I changed it to HQ [high] and it now works.
It even inserts the [Favorites] into the list as well, so it turns out that the Favorites has a thumbnail after all... Go figure.
I did this, and it keeps the [Favorites] out.
If Not item.Snippet.Title = "Favorites" Then
' Insert statement here
end if
Works like a charm now, with the [high] in-place now.
All is good.
This thread has now come to an end.

What you have here is a json object. Json objects represent javascript objects which are *usually* serialized as strings.
The curly braces ({}) identify regular objects. A regular json object contains key:value pairs delimited by commas; e.g. -
Open in new window
The object I just defined would be best represented like this in C# -Open in new window
Or this in VB.NET -Open in new window
Some objects can be well defined; e.g. -Open in new window
To work with this definition, our C#/VB.NET would have their class name changed to "OneTwo" (you could also use an Attribute to decorate the class instead of naming it); e.g. -Open in new window
Or this in VB.NET -Open in new window
The brackets ([]) identify array objects. Array objects contain json objects delimited, again, by commas; e.g. -Open in new window
If I were to deserialize the above, I would construct either an array or a list in C#/VB.NET.Again keep in mind that arrays, and their contents can be well-defined; e.g. -
Open in new window
The property/field definitions (kind, etag, snippet, etc) have meaning to the service that you are retrieving the data from.Now what I think is confusing you is the ToString methods. What you are seeing here is a parameterized form of string concatenation.
Open in new window
Literally outputs 'My favorite color is blue and I like eating spaghetti.'I overrode the ToString() function so that I could provide easy output to the console. To put this another way, I could have used a more verbose method instead:
Open in new window
Which would produce the exact same output as above.The Kind: {1} means that the string value for {1} is the second parameter (zero based counting) in the parameter list, in this case the Kind property of the Playlist object.
The Items: {5} means that the string value for {5} is the sixth parameter (zero based counting) in the parameter list, in this case String.Join(Environment.Ne
