Question

Using this code i get the line of characters which I want to store in a variable

string find = textBox1.Text;
string lineText = null;
int lineNum = richTextBox1.GetLineFromCharIndex(richTextBox1.Find(find));
MessageBox.Show("Line Number is " + lineNum);

How can I store the resulted line text from richTextBox in string variable.

You can use the Lines[] array:

int charNum = richTextBox1.Find(find);
if (charNum > -1) {
  lineText = richTextBox1.Lines[richTextBox1.GetLineFromCharIndex(charNum)];
}
