VB.NET need a class property to be a list array - part 2

I think I need a break

I have been racking my brain trying this all day
hehehehehe

Im trying this because I would like to do a vb class how has several properties with diferents types like strings, doubles, arrays, etc...


Originally I try with arrays as properties in my class but I check and in diferents blogs several programmers says that I would be better I use a list as properties in my class instead of arrays.

That was Im checking how to use list as properties

This is what I have

Class data
    Private dmyarray(,) As Boolean
    Public Property myarray() As Boolean(,)
        Get
            Return dmyarray
        End Get
        Set(ByVal value As Boolean(,))
            dmyarray = value
        End Set
    End Property
End Class

Select allOpen in new window

I would like to know how to do the same but with a list

hi codecruiser

As I say

In the original project for example:
I had several variables and several arrays that allow me to do some operations.

the data saved on this variables and arrays allows to create a graph.

When the work is finished the data is saved in xml files that represent the graphs (this is not a database).

This xml files the user can move it to others computers with the same program  recreate the graphs or make a new ones.

------------------------------------------------------------------------------------------------------------------------------
In the new version the idea is that in a main project I have a treeview, and when I add a new branch I need to use the same variables and arrays.

but what happend if I add a new branch????, thats way I create a class with several properties that represents the variables and the arrays.

right now Im using arrays in my properties and they works great, but checking in several blogs many programmers says that it is not the best idea if that I use arrays that it would be better if I use a bidimensional list as a properties in my class

best regards

Without looking at all your code, I think DataTables may be more suitable for you given that you have graphs(data points) and XML involved.

datatable it is not a option beacause every the program not need a database.

My program create xml files as excel create xls files or word create doc files.

ok thanks thats a great idea, im gonna use it in this project

but it is not what I mean for this issue

I think that I need to explain my self a little better

this is an example of my class

Public Class data
    Private dmyarray1(,) As String
    Public Property myarray1() As String(,)
        Get
            Return dmyarray1
        End Get
        Set(ByVal value As String(,))
            dmyarray1 = value
        End Set
    End Property

    Private dmyname As String
    Public Property myname() As String
        Get
            Return dmyname
        End Get
        Set(ByVal value As String)
            dmyname = value
        End Set
    End Property

    Private dmydouble As Double
    Public Property mydouble() As Double
        Get
            Return dmydouble
        End Get
        Set(ByVal value As Double)
            dmydouble = value
        End Set
    End Property
End Class

Select allOpen in new window

when the program starts the user has a default branch in the treeview where he can prepare graphs and solve math algorithms

when the user introduce data in the branch I use the following code

        Dim newtest As new data
        newtest.myname = "Carlos" & str(indexbranch)
        newtest.myarray1(0, 0) = "4.5"
        newtest.mydouble = 4.5

       mydictionary.add(newtest.myname,newtest)

Select allOpen in new window

if the user wants, he can add a new branch where he can prepare another graphs and solve another math algorithms, at this point the program needs to use the same variables and arrays but using other values.

Because the user can work with both branch at same time thats way I create a custom class with that can handle all this variables and arrays.

When the user finished if he wants he can save their work, at this point I use xml file to save the information storage in my class.

At this point the class and the dictionary works great and without a problem.

But searching options on internet to improve my code, I read that Many programmers in diferents blogs says  that it is better to use list instead of arrays

Thats way Im tring to explore the optio to use generic list as properties in my class instead of arrays as properties in my class

>I read that Many programmers in diferents blogs says  that it is better to use list instead of arrays

That does not just apply to everyone. Arrays exist for a reason. If arrays are doing the job for you and you do not have any issues then I think you do not need to convert to lists.

ok

I thing youre right

I would have liked to know how to do it, but I need to continue

thanks anyway

thanks a lot for your time
