Can't set value of RichTextBox.Lines[index]

[CarNagE]

I'm working on a simple editor and tried to set the contents of my instance of a RichTextBox by using its Lines-property. According to the MSDN, it provides a set-modifier.

 

I wondered when I tried

myRichTextBox.Lines[0] = "bla"; 

and nothing happened to the contents of my RTFBox...

 

Can anyone tell me, what I'm doing wrong?

The array property as a whole is read/write, so you'd have to do something like this:

 

string[] myarray = myRTB.Lines;
myarray[0] = "blah";
myRTB.Lines = myarray;
