Answer 1

if ((keyData == (Keys.Control | Keys.C)) || keyData == (Keys.Control | Keys.V))
  {
  IDataObject data = Clipboard.GetDataObject();//从剪贴板中获取数据
  if (Clipboard.ContainsText(TextDataFormat.Html))
  {
  System.IO.MemoryStream vMemoryStream =
  Clipboard.GetData("Html Format") as System.IO.MemoryStream;
  vMemoryStream.Position = 0;
  byte[] vBytes = new byte[vMemoryStream.Length];
  vMemoryStream.Read(vBytes, 0, (int)vMemoryStream.Length);
  this.Text = Encoding.UTF8.GetString(vBytes);
  }
  else if (data.GetDataPresent(DataFormats.Text))
  {
  this.Text = data.GetData(DataFormats.Text).ToString();
  }

Answer 2

就是当我在textbox粘贴时，我将不执行原有的粘贴，替换成我写的后台写的东西

Answer 3

将属性里的shortcutsEnabled设为false看行不行

Answer 4

        private void textBox2_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyData == (Keys.Control | Keys.V))
            {
                e.Handled = true;
                MessageBox.Show("asdfsadfhkjasdhfkjasd");
            }
        }
根本没法执行了

Answer 5

查 拦截热键，判断ctrl和v

Answer 6

 textBox1.ShortcutsEnabled = false;private void textBox1_KeyUp(object sender, KeyEventArgs e)
        {
            if (e.Control && e.KeyCode == Keys.V)
            {
                int start = textBox1.SelectionStart;                 
                string text = textBox1.Text.Substring(0, start) + "我是替换文本"; 
                textBox1.Text = text + textBox1.Text.Substring(start + textBox1.SelectionLength);
                textBox1.SelectionStart = text.Length;
            }
        }
