Question

我有一个程序，我有一个.exe文件。 .exe的工作是扫描目录中是否存在损坏的文件。如果通过命令提示符以下列格式访问，我将获得扫描结果

“exe”的位置“”要扫描的文件或文件夹“

我得到的结果是扫描继续进行。喜欢

D:\A scanned
D:\B scanned
D:\C scanned
D:\D scanned

现在我的问题是如何使用c＃逐行获得结果。

我正在使用以下代码集，我只得到最终结果。我需要逐行输出

代码如下：

        string tempGETCMD = null;
        Process CMDprocess = new Process();
        System.Diagnostics.ProcessStartInfo StartInfo = new System.Diagnostics.ProcessStartInfo();
        StartInfo.FileName = "cmd"; //starts cmd window
        StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        StartInfo.CreateNoWindow = true;
        StartInfo.RedirectStandardInput = true;
        StartInfo.RedirectStandardOutput = true;
        StartInfo.UseShellExecute = false; //required to redirect
        CMDprocess.StartInfo = StartInfo;
        CMDprocess.Start();
        System.IO.StreamReader SR = CMDprocess.StandardOutput;
        System.IO.StreamWriter SW = CMDprocess.StandardInput;
        SW.WriteLine("@echo on");
        SW.WriteLine(@"E:\Scanner\Scanner.exe -r E:\Files to be scanned\"); //the command you wish to run.....


        SW.WriteLine("exit"); //exits command prompt window
        tempGETCMD = SR.ReadToEnd(); //returns results of the command window
        SW.Close();
        SR.Close();
        return tempGETCMD;

任何有关这方面的帮助都会受到赞赏

谢谢，

我认为您必须使用专用线程来读取StandardOutput流中的每一个新行，如下所示：

    //This will append each new line to your textBox1 (multiline)
    private void AppendLine(string line)
    {
        if (textBox1.InvokeRequired){
            if(textBox1.IsHandleCreated) textBox1.Invoke(new Action<string>(AppendLine), line);
        }
        else if(!textBox1.IsDisposed) textBox1.AppendText(line + "\r\n");
    }
    //place this code in your form constructor
    Shown += (s, e) => {
      new Thread((() =>
      {          
        while (true){
           string line = CMDProcess.StandardOutput.ReadLine();
           AppendLine(line);    
           //System.Threading.Thread.Sleep(100); <--- try this to see it in action   
       }
     })).Start();
   };
   //Now every time your CMD outputs something, the lines will be printed (in your textBox1) like as you see in the CMD console window.

如何使用c＃使用命令提示符并逐行获取结果？
