going line-by-line through a Multiline textbox

[nickmollberg]

I have a big textbox (100 lines) that I need to read through, one line at a time.

Basically, I need to pass it, one line at a time to a parsing method. I should just loop through it until I reach the end, I suppose.

What would be the syntax to loop, line by line, through a texbox?

Use the Lines property.

Show All
Gets or sets the lines of text in a text box control.

[Visual Basic]
Public Property Lines As String ()

[C#]
public string[] Lines {get; set;}
Property Value
An array of strings that contains the text in a text box control.

Remarks
Each element in the array becomes a line of text in the text box control. If the Multiline property of the text box control is set to true and a newline character appears in the text, the text following the newline character is added to a new element in the array and displayed on a separate line.

Sorry, I'm not finding this attribute...

if this is going to be a lot of lines, can you store each line of a list box, instead of a text box? At least the index of the list box could provide a nice number to loop with.....though if John has a better way, definitely listen to him, he's a bad man.

Good luck,

Is the Application for Windows Forms or ASP.Net?

In Windows Forms, I have no trouble with

Dim a() As String = txtbox.Lines

nickmollberg,

OK, here's what you do (and in C# even!) ...

you've created your form with a multiline textbox, right? If so, you can loop through each line this way (on a button click event):

private void button1_Click(object sender, System.EventArgs e)
{
    string[] lines = textBox1.Lines;

    for(int i = 0; i < lines.GetUpperBound(0); i++)
    {
        MessageBox.Show(lines[i]);
    }
}

and, as you probably know, "lines" is equal to a string, so at that point do whatever processing you have to do.

Hope that helps.
