if(line.StartsWith("-->"))
{
//here is my problem, how to can change the font in the spectific line...
}
}
string[] textBoxLines = richTextBox1.Lines;
for (int i = 0; i < textBoxLines.Length; i++)
{
string line = textBoxLines[i];
if (line.StartsWith("-->"))
{
richTextBox1.SelectionStart = richTextBox1.GetFirstCharIndexFromLine(i);
richTextBox1.SelectionLength = line.Length;
richTextBox1.SelectionFont = yourFont;
}
}
richTextBox1.SelectionLength = 0;//Unselect the selection
