string.IndexOf help

[Guest]

In my project I want to search thru a text in a text box or RichTextBox.

When I search I want to list all lines that contain the string I am
searching for.

e.g.

one plus four
two plus four
three plus four
one minus four
one divided by four
two minus four
two divided by four
three plus five
three minus five

search for the string "one", and display the contents of all lines in the
TextBox/RichTextBox.

I envision that the TextBox/RichTextBox would be a control that is hidden
normally and then the search form would resize and show the
TextBox/RichTextBox control with the results.

Could someone please post a sample?

Thanks,

Brian

Hi,
I think you are looking for something like below:
static int previndex;
private void button1_Click(object sender, System.EventArgs e)
{
for(int lineno = 0;lineno < richTextBox1.Lines.GetLength(0);lineno++)
{
previndex = richTextBox1.Find("one",previndex,RichTextBoxFinds.WholeWord
);
int richtextboxlineno =
richTextBox1.GetLineFromCharIndex(richTextBox1.Find("one",previndex,RichTextBoxFinds.WholeWord ));
if (previndex ==0 )
{
previndex++;
}
richTextBox2.AppendText(richTextBox1.Lines[richtextboxlineno]);
}
}

Hi Rammer, I am looking for a sample/snipit of how to utilize the IndexOf
method that makes better sense than the ones on the MSDN Library.

I am just not grasping that one.

Manish that example I think will meet the needs and educates me further.

I will substitue the fixed string into a variable, so that I can search for
different stuff.

I appreciate the example.

Many Thanks,

richTextBox2.AppendText(richTextBox1.Lines[richtextboxlineno]);
