我怎樣才能找到一個動態創建的按鈕？

Question

我正在製作一個包含Tic Tac Toe遊戲的客戶端/服務器應用程序，其中兩個連接的客戶端可以玩遊戲。 3 x 3網格由9個動態創建的按鈕組成。 當第一個客戶端單擊網格上的按鈕時，該按鈕被禁用，並且內容顯示「X」。值被髮送到服務器，然後發送到其他連接的客戶端。根據客戶收到的價值，我希望禁用同一個按鈕，並將內容更改爲'X'。

我遇到的問題是找到在客戶端動態創建的按鈕。 任何幫助表示讚賞！

//Dynamically created 9 buttons on the client 
private void initBoard(int rank) 
    { 

     board = new tttBoard(rank); 
     boardGrid.Children.Clear(); 
     boardGrid.Rows = rank; 
     for (int i = 0; i < rank; i++) 
     { 
      for (int j = 0; j < rank; j++) 
      { 
       newButton = new Button(); 
       newButton.Tag = new Point(i, j); 
       newButton.Name = "b" + i.ToString() + j.ToString(); 
       newButton.Content = newButton.Tag; 
       boardGrid.Children.Add(newButton); 
      } 
     } 
    } 

//Method that receives data - CheckButton called method within this 
public void OnDataReceived(IAsyncResult ar) 
    { 
     try 
     { 
      SocketPacket sckID = (SocketPacket)ar.AsyncState; 
      int iRx = sckID.thisSocket.EndReceive(ar); 
      char[] chars = new char[iRx]; 
      Decoder d = Encoding.UTF8.GetDecoder(); 
      int charLen = d.GetChars(sckID.dataBuffer, 0, iRx, chars, 0); 
      szData = new String(chars); 
      this.Dispatcher.Invoke((Action)(() => 
      { 
       if(szData.Contains("Clicked button : ")) 
       { 
        return; 
       } 
       else 
        lbxMessages.Items.Add(txtMessage.Text + szData); 
      })); 

      ClickButton(); 

      WaitForData(); 
     } 
     catch (ObjectDisposedException) 
     { 
      Debugger.Log(0, "1", "\n OnDataRecieved: Socket has been closed\n"); 
     } 
     catch(SocketException se) 
     { 
      MessageBox.Show(se.Message); 
     } 
    } 

//based on the message received from the server, I check to see if 
//it contains "Clicked button: " and a value that I use to locate the correct 
//button to disable and change content to 'x' to represent the move made by the 
//other client 

public void ClickButton() 
    { 
     if (szData.Contains("Clicked button : ")) 
     { 
      value = szData.Substring(17, 1); 
     } 
     this.Dispatcher.Invoke((Action)(() => 
     { 
      btnName = "b0" + value; 
      object item = grdClient.FindName(btnName);//boardGrid.FindName(btnName); 
      if (item is Button) 
      { 
       Button btn = (Button)item; 
       btn.IsEnabled = false; 
      } 
     })); 
    }

您是否擁有客戶端代碼？如果是這樣，這聽起來像你讓它比它需要更困難。你爲什麼不簡化3x3數組的實現，該數組包含對每個井字頭位置按鈕的引用。然後，您只需從客戶端消息中提取按鈕的座標，並在另一個客戶端上的相同位置更新該按鈕。

例如，消息「點擊按鈕：2,1」將轉化爲：

buttonArray[2,1].Enabled = false; 

，或者你需要的任何其他做的按鈕。
