假設的WinForms ...

這裏有一個簡單的例子：

public partial class Form1 : Form 
{ 

    private const int WM_SETREDRAW = 0xB; 

    [System.Runtime.InteropServices.DllImport("user32.dll")] 
    public static extern int SendMessage(IntPtr hWnd, Int32 wMsg, bool wParam, Int32 lParam); 

    private Dictionary<string, string> replacements = new Dictionary<string, string>(); 

    public Form1() 
    { 
     InitializeComponent(); 

     replacements.Add("cx", "ĉ"); 
     replacements.Add("ae", "æ"); 
     // etc... 
    } 

    private void richTextBox1_TextChanged(object sender, EventArgs e) 
    { 
     if (cbAutoReplacements.Checked) 
     { 
      int prevStart = richTextBox1.SelectionStart; 
      int prevLength = richTextBox1.SelectionLength; 
      SendMessage(richTextBox1.Handle, WM_SETREDRAW, false, 0); 

      int index; 
      int start; 
      foreach (KeyValuePair<string, string> pair in replacements) 
      { 
       start = 0; 
       index = richTextBox1.Find(pair.Key, start, RichTextBoxFinds.MatchCase); 
       while (index != -1) 
       { 
        richTextBox1.Select(index, pair.Key.Length); 
        richTextBox1.SelectedText = pair.Value; 
        index = richTextBox1.Find(pair.Key, ++start, RichTextBoxFinds.MatchCase); 
       } 
      } 

      richTextBox1.Select(prevStart, prevLength); 
      SendMessage(richTextBox1.Handle, WM_SETREDRAW, true, 0); 
      richTextBox1.Invalidate(); 
     } 
    } 

}
