示例1: Button1_Click
// This method demonstrates retrieving line numbers that

{
// Reset the results box.
TextBox1.Text = "";
// Get the word to search from from TextBox2.
string searchWord = TextBox2.Text;
int index = 0;
//Declare an ArrayList to store line numbers.
System.Collections.ArrayList lineList = new System.Collections.ArrayList();
do
{
// Find occurrences of the search word, incrementing
// the start index.
index = RichTextBox1.Find(searchWord, index+1, RichTextBoxFinds.MatchCase);
if (index!=-1)
// Find the word's line number and add the line
// number to the arrayList.
{
lineList.Add(RichTextBox1.GetLineFromCharIndex(index));
