Replacing texts

[shivam0101]

Hi,

Is it possible to replace lines of texts in richtextbox in C#?

like,
start_line = 3, end_line= 10

for(i=start_line; i< end_line; i++)
{
rtb.replaceText(i);
}

Thanks

Is this all of your code? What are you trying to replace it with? Your current form will do nothing.

rtb.Text = rtb.Text.Replace(“what to replace”, “what to replace with”);
