C#控制事件的触发方式

我有一个问题： 我有一个两个按钮，单击一次调用XmlHelper类中的CreateTelegram（）函数。 该函数创建一个Xml并将其发送到服务器。 如果服务器响应（xml），则会触发一个事件。 现在，如果XML元素returnCode=0，我将把Textfield Backcolor属性编辑为绿色

如何获取触发事件的控件（按钮1或按钮2）

这是我的代码：

按钮1:

private void btnCheckId_Click(object sender, EventArgs e)
{
  xmlHelper.CreateTelegram(configSettings, txtIdCheck.Text);
}

private void btnCheckId2_Click(object sender, EventArgs e)
{
  xmlHelper.CreateTelegram(configSettings, txtIdCheck2.Text);
}

 public void CreateTelegram(ConfigSettings configSettings, string Identifier)
    {
      XmlWriterSettings settings = new XmlWriterSettings();
      settings.Indent = true;
      settings.IndentChars = ("    ");
      settings.CloseOutput = true;
      //settings.OmitXmlDeclaration = true;
      using (StringWriter sw = new StringWriter())
      {
        using (XmlWriter writer = XmlWriter.Create(sw, settings))
        {

         xml Stuff..

        }
        
        string partTelegram = sw.ToString();

        SendTelegramm(partTelegram , configSettings.serverAddress, configSettings.serverPort);
      }
    }

_connector.DataReceived += new EventHandler<SocketEventArgs<byte[]>>(Connector_DataReceived);

按钮2:

private void btnCheckId_Click(object sender, EventArgs e)
{
  xmlHelper.CreateTelegram(configSettings, txtIdCheck.Text);
}

private void btnCheckId2_Click(object sender, EventArgs e)
{
  xmlHelper.CreateTelegram(configSettings, txtIdCheck2.Text);
}

 public void CreateTelegram(ConfigSettings configSettings, string Identifier)
    {
      XmlWriterSettings settings = new XmlWriterSettings();
      settings.Indent = true;
      settings.IndentChars = ("    ");
      settings.CloseOutput = true;
      //settings.OmitXmlDeclaration = true;
      using (StringWriter sw = new StringWriter())
      {
        using (XmlWriter writer = XmlWriter.Create(sw, settings))
        {

         xml Stuff..

        }
        
        string partTelegram = sw.ToString();

        SendTelegramm(partTelegram , configSettings.serverAddress, configSettings.serverPort);
      }
    }

_connector.DataReceived += new EventHandler<SocketEventArgs<byte[]>>(Connector_DataReceived);

XmlHelper:

private void btnCheckId_Click(object sender, EventArgs e)
{
  xmlHelper.CreateTelegram(configSettings, txtIdCheck.Text);
}

private void btnCheckId2_Click(object sender, EventArgs e)
{
  xmlHelper.CreateTelegram(configSettings, txtIdCheck2.Text);
}

 public void CreateTelegram(ConfigSettings configSettings, string Identifier)
    {
      XmlWriterSettings settings = new XmlWriterSettings();
      settings.Indent = true;
      settings.IndentChars = ("    ");
      settings.CloseOutput = true;
      //settings.OmitXmlDeclaration = true;
      using (StringWriter sw = new StringWriter())
      {
        using (XmlWriter writer = XmlWriter.Create(sw, settings))
        {

         xml Stuff..

        }
        
        string partTelegram = sw.ToString();

        SendTelegramm(partTelegram , configSettings.serverAddress, configSettings.serverPort);
      }
    }

_connector.DataReceived += new EventHandler<SocketEventArgs<byte[]>>(Connector_DataReceived);

\u connector.DataReceived+=新事件处理程序（connector\u DataReceived）；

连接器的数据接收功能

   private void Connector_DataReceived(object sender, SocketEventArgs<byte[]> e)
    {
      if (e == null || e.Repository == null)
        return;
      if (_currentMsg != null)
      {
        {
          try
          {
            _currentMsg.ResponseMessage = new XmlMessage(EvaluateReceivedData(e.Repository), false);
          }
          catch (Exception ex)
          {
            ShowTextThreadProc(ex.Message + Environment.NewLine + ex.StackTrace);
          }
          return;
        }
      }
      EvaluateReceivedData(e.Repository);
    }


private string EvaluateReceivedData(byte[] data)
{
  int offset = (int)this._connector.Offset;
  if (data == null || data.Length <= offset)
    return null;
  string msg = Encoding.ASCII.GetString(data, offset, data.Length - offset);

  DisplayMessage(msg);
  return msg;
}

 private void DisplayReceivedData(string text)
    {
      try
      {
        XmlDocument doc = new XmlDocument();
        doc.Load(new StringReader(text));


         int returnCode = Convert.ToInt32(doc.SelectSingleNode("/root/event/result/@returnCode")?.Value ?? "-1");
     
        Debug.WriteLine(returnCode );

        if (returnCode == 0)
        {
          ...GET THE SENDER and edit the BackColor...
        }


      }
      catch (Exception ex)
      {
        MessageBox.Show(ex.Message);
      }
      finally 
      {
        Disconnect();
      }
    }

private void Connector\u数据已接收（对象发送方，SocketEventArgs e）
{
if（e==null | | e.Repository==null）
返回；
如果（_currentMsg！=null）
{
{
尝试
{
_currentMsg.ResponseMessage=newXMLMessage（EvaluateReceivedData（e.Repository）），false；
}
捕获（例外情况除外）
{
ShowTextThreadProc（ex.Message+Environment.NewLine+ex.StackTrace）；
}
返回；
}
}
评估接收到的数据（如存储库）；
}
专用字符串EvaluateReceivedData（字节[]数据）
{
int offset=（int）this.\u connector.offset；
如果（data==null | | data.Length您可以强制转换
sender
参数：

private void btnCheckId_Click(object sender, EventArgs e)
{
    Button clickedButton = (Button)sender;
    if (clickedButton == Button1)
    { ... }
}

享受这个10年历史的复制品：对不起，我有两个不同的按钮。我编辑了代码哦，对不起，按钮不一样。问题是datareceived函数中的问题。我如何才能找到单击的按钮？你是指最后一个单击的按钮吗？存储对它的引用。或者，
\u connector.datareceived
如何连接到按钮单击…？是的上次单击的按钮。如果接收到来自服务器的数据，Datareceived将触发。因此，将
clickedButton
存储在类中的一个字段中：
private Button\u clickedButton；
好的。我想我必须使用事件，但存储单击的按钮是正确的方法吗？
