聊天Boubbles WindowsForms c＃

Question

我使用以下问题中的代码收到错误： Control snapping on resize in C# scrollable container 错误来自这一部分：

for (int x = 0; x < 20; x++)
{
    messageControl1.Add(x.ToString("00") + ": Testing testing testing ...",
      MessageControl.BubblePositionEnum.Right);

    messageControl1.Add(x.ToString("00") + ": Testing with variable length strings.  This one is longer!", 
      MessageControl.BubblePositionEnum.Right);

    messageControl1.Add(x.ToString("00") + ": Testing is fun.", 
      MessageControl.BubblePositionEnum.Left);
}

它强调“添加”。
