Read TextBox line by line

[ravenfrost]

Hello,

I have a text box that I am entering items into line by line. I want to read in the data one line at a time into a variable through a loop. I know the textbox does not have a readline attribute, but is there any way I can read a textbox line by line, or should I be using a different control to do so? I'm using VB.Net. Thanks.

I would assume it to have a Environment.NewLine at the end of each line, so you could split by that. I will come back to this thread in like 30 minutes when I get some time to look it up exactly for you.

Ya, doing this:

MyMultiLineTextBox.Text.Split(Environment.NewLine)

will return an array of strings, one for each line.

Thanks I'll give it a whirl!

Only problem I'm having is that it's keeping the carriage returns within the string. Any way to get rid of those?

Use .Trim() on each line?

string[] mylines = mytextbox.Split(Environment.Newline);
for(int i=0;i<mylines.Length;i++)
{
   string currentstring=mylines[i].Trim();
}

Fore some reason the trim isn't removing the carriage return. The first variable in teh array doesn't ahve it, but all other variables have a carraige return before them.

                    Dim strComputer, arrComputers() As String
arrComputers = txtEndpoints.Text.Split(Environment.NewLine)
Dim i As Integer = 0
For i = LBound(arrComputers) To UBound(arrComputers)
     strComputer = Trim(arrComputers(i))
     Call MsgBox(strComputer)
Next

Ah ha!
There is probably both a \n and a \r and your environment.newline is only removing \r.
Investigate Trim() and Split() and find out where to handle that.
OR

string mytext=mytextbox.text;
mtext.Replace("\r","");
 

then do a .Split("\n"); and see where it gets you?
