Format text in Rich Text Box

I am using the following code to load a text file into a rich text box:

System.IO.StreamReader l_reader = new System.IO.StreamReader("c:\\test.txt");
           
 richTextBox1.Text = l_reader.ReadToEnd();

How do I format this text once it's displayed in the text box?  Say, I wanted to bold every instance of the word "Date", for example.

Thanks!

Do you want something like this?

System.IO.StreamReader l_reader = new System.IO.StreamReader("c:\\test.txt");
richTextBox1.Text = l_reader.ReadToEnd();
int pos = -1;
for(int i=0;i<richTextBox1.Text.Length;i++)
{
  pos = richTextBox1.Find("Date",pos+1,RichTextBoxFinds.MatchCase);
  if(pos!=-1)
     richTextBox1.Select(pos,4);
   richTextBox1.SelectionFont = new Font(
   richTextBox1.SelectionFont.FontFamily,
   richTextBox1.SelectionFont.Size,
   FontStyle.Bold
  );
i = i+pos;
}

Chester,

Yes!  However, it only bolds the first few instances of the word "Date", and highlights one as well.  The rest are the same.

Sorry for that non-perfect code, try with this one,

System.IO.StreamReader l_reader = new System.IO.StreamReader("c:\\a.txt");
richTextBox1.Text = l_reader.ReadToEnd();
int pos = -1;
for(int i=0;i<richTextBox1.Text.Length;i++)
{
      pos = richTextBox1.Find("Date",pos+1,RichTextBoxFinds.MatchCase);
      if(pos!=-1)
      {
            richTextBox1.Select(pos,4);
            richTextBox1.SelectionFont = new Font(
                            richTextBox1.SelectionFont.FontFamily,
                  richTextBox1.SelectionFont.Size,
                  FontStyle.Bold);
      }
}
