覆蓋粘貼操作列表框

Question

當用戶粘貼到列表框中時，我希望剪貼板中的內容以單獨項目的形式排列。分割文本將由換行符完成。

如果您的表單上有ListBox控件（我們稱之爲listBox），則應該處理其KeyDown事件。

這裏的例子：

private void listBox_KeyDown(object sender, KeyEventArgs e) 
{ 
    // Check that the button pressed is V, that Control is also pressed and that the clipboard contains text. 
    if ((e.KeyCode == Keys.V) && e.Control && Clipboard.ContainsText()) 
    { 
     // Get text from clipboard and separate it. 
     string text = Clipboard.GetText(); 
     string[] textLines = text.Split(
      new string[] { Environment.NewLine }, 
      StringSplitOptions.RemoveEmptyEntries); // or don't 

     // Add lines to listBox items. 
     listBox.Items.AddRange(textLines); 

     // Mark event as handled. 
     e.Handled = true; 
    } 
}
