C＃WPF讀取控制檯輸出

Question

我正在編寫一個應用程序，顯示您在Ethereum（像比特幣這樣的加密貨幣）中的當前哈希率，並且我需要以某種方式從正在運行的命令行獲取連續輸出。這是我到目前爲止，但它不打印到程序輸出：

pProcess.OutputDataReceived += new DataReceivedEventHandler((sender, e) => 
{ 
    // Prepend line numbers to each line of the output. 
    if (!String.IsNullOrEmpty(e.Data)) 
    { 
     System.Console.Write(e.Data); 
    } 
}); 

//Wait for process to finish 
pProcess.WaitForExit(); 

什麼是不適用於此代碼？我猜測事件處理程序有些東西搞砸了，但我不知道是什麼。

複製並粘貼到您的代碼，我修改爲你：

     public partial class MainWindow : Window 
     {

       InitializeComponent(); 
      } 

      private void MineButton_Click(object sender, RoutedEventArgs e) 
      { 
       Task.Run(() => { startMining(); }); 
      } 

      public void startMining()

       //strCommand is path and file name of command to run 
       pProcess.StartInfo.FileName = @"E:/Documents/ETH/ETHMinerVisualiser/ethminer-cuda-0.9.41-new/ethminer.exe"; 

       //strCommandParameters are parameters to pass to program

       pProcess.StartInfo.UseShellExecute = false; 


       //Set output of program to be written to process output stream 
       pProcess.StartInfo.RedirectStandardOutput = true; 

       //Optional 
       pProcess.StartInfo.WorkingDirectory = ""; 

       //Start the process 
       pProcess.Start(); 

       //pProcess.StartInfo.CreateNoWindow = true; 

       //pProcess.BeginOutputReadLine(); 

       pProcess.OutputDataReceived += new DataReceivedEventHandler((sender, e) => 
       { 
        // Prepend line numbers to each line of the output. 
        if (!String.IsNullOrEmpty(e.Data)) 
        { 
         //System.Console.Write(e.Data);     
         Debug.WriteLine(e.Data); 
        } 
       }); 

       //Wait for process to finish 
       pProcess.BeginOutputReadLine(); 

       pProcess.WaitForExit(); 
      } 
     } 
    }
