C＃CMDのPingタイムスタンプ

Question

私はまたSystem.DateTime.Today.ToString（ "MM-DD-YYYY"）が、プログラムでそのsayngしようと試みたのC＃

で作業ピングタイムスタンプを取得する方法を把握しようとしています間違ったホスト。

フォームデザイン示すモーメントのpingで

：

私はこのコードを使用しようとしました：

ping -t 127.0.0.1|cmd /q /v /c "(pause&pause)>nul & for /l %a in() do (set /p "data=" && echo(!date! !time! !data!)&ping -n 2 127.0.0.1>nul"

      } 
      log = new StreamWriter(fileStream); 
      log.WriteLine(strLog); 
      log.Close(); 
     } 

     private void checkBox1_CheckedChanged(object sender, EventArgs e) 
     { 

     } 
    } 
} 

私はそれをデバッグしましたが、それは何かエラーや何かを言っていません。

Answer 1

コマンドが実行されたスレッドが例外をスワップするため、エラーは発生しません。

public void thread1() 
    { 
     try 
     { 
      string command = "/c ping -t " + textBox1.Text + "|cmd /q /v /c (pause&pause)>nul & for /l %a in() do (set /p " + "data" + '=' + " && echo(!date! !time! !data!)&ping -n 2" + textBox1.Text + ">nul"; 
      ProcessStartInfo procStartInfo = new ProcessStartInfo("CMD", command); 
      Process proc = new Process(); 
      proc.StartInfo = procStartInfo; 
      procStartInfo.RedirectStandardOutput = true; 
      procStartInfo.RedirectStandardInput = true; 
      procStartInfo.RedirectStandardError = true; 
      procStartInfo.UseShellExecute = false; 
      procStartInfo.CreateNoWindow = true; 
      proc.OutputDataReceived += new DataReceivedEventHandler(proc_OutputDataReceived); 
      proc.ErrorDataReceived+= new DataReceivedEventHandler(proc_ErrorDataReceived); // add error output 
      proc.Start(); 
      proc.BeginOutputReadLine(); 
      proc.BeginErrorReadLine(); // begin read error output 
      proc.WaitForExit(); 
     } 
     catch (Exception ex) // add ex here so you can look into it. 
     { // <== Breakpoint here 
      //if an error occurs with in the try block, it will handled here. 
     } 
    } 

これをデバッグするために、複数の方法があります。

1. 上記の行にブレークポイントを設定します。

2. [すべての例外を有効にする]を選択し、[共通言語ランタイム例外]が完全にチェックされるまでチェックします。

3. また、プロセスはErrorDataReceivedを確認する必要があります。
