String Parsing in Vb.Net or C#.Net

I have a uri string,

Sample format :- ftp://hostname:portnumber/../../folderpath/

Expected format would be :- ftp://hostname:portnumber/../../myfolder/myfolder/myfolder/

hostname could be an Ip config or computername

I have to parse the uri string  and pick the HostName, PortNumber and Folder Path seperately.

On what logic, I have to go through this process.

Use the Uri class:

e.g.

Uri u = new Uri("ftp://hostname:portnumber/../../folderpath/");
string host = u.Host;
int port = u.Port;
string path = u.PathAndQuery;

Open in new window

Great, I was worried that i should go for some substring function.

I didnt know that Uri is an inbuilt class.

Thank you !!!

The only caveat I would provide is that if you for some reason need the "/../.." part, then you may need to do string parsing--the Uri class seems to consume that bit; not sure why.

Yes, i am facing that issue.


 Dim sPath As String = String.Empty

        sPath = sUri.PathAndQuery.ToString()

        sPath = sPath.Replace("%2F", "/")
        sPath = sPath.Replace("%2E", "/")

sPath = sPath.Replace("/../../","")

Open in new window

OK, for clarity:  Do you need "../../myfolder/myfolder/myfolder/" or "myfolder/myfolder/myfolder/" returned?

I need "myfolder/myfolder/myfolder/"


My requirement is to get the uri from config file and create a sftp link.

sftp://username:password@hostname:portnumber//folderpath/

If i am able to get "myfolder/myfolder/myfolder/" , I can concatenate with the existing string

As far as I saw, that is what the code I posted above returns:

All I was saying earlier was that if for some reason it needed to be:

"../../folderpath/"

...that you saw in the path variable, then the Uri class seems to mangle that bit, as visible in the above image.
