在C＃中，如果程序不断输出，您如何从DOS程序中读取？
我找到了很多关于如何执行cmd.exe并执行命令的编码示例，甚至执行nslookup和交互，但我遇到的问题是使用特定的dos程序，当它启动时，它不会停止“输出” 。 这里有一些代码，我会发表评论和我从C＃得到的错误
这是我如何以更高级的方式设置它，以便我可以从事件的程序接收输出
public void StartApplication(string appNameAndPath) { StreamReader outputStream; Process p = new Process(); p.StartInfo.FileName = appNameAndPath; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.UseShellExecute = false; p.StartInfo.CreateNoWindow = false;//for now just so I can see it p.Start(); //here is my advanced example if(advanced == true) { outputStream = p.StandardOutput; DoReadOutPut(); } else {//here is a simple example while (p.StandardOutput.ReadLine() != null) //this hangs here until the application exists { txt += (p.StandardOutput.ReadLine()); } } } void DoReadOutput() { outputStream.BaseStream.BeginRead( readOutputBuffer, 0, readOutputBuffer.Length, new AsyncCallback( OnReadOutputCompleted ), null ); //this does sometimes fire but only with 0 bytes, on other dos programs it would say Memory read not allowed } void OnReadOutputCompleted( IAsyncResult result ) { int cbRead = outputStream.BaseStream.EndRead( result ); ProcessOutput( readOutputBuffer, cbRead ); DoReadOutput(); } private void ProcessOutput(byte[] buffer, int cbRead) { string text = p.StartInfo.StandardOutputEncoding.GetString(buffer, 0, 10000); //this is where it hangs until the program exits or is not writing anymore this.Invoke((Action)delegate { SetTextBoxValue(text);//im doing this because im on another thread otherwise textBox1.Text - text" }); } 我不想使用API和GetText并为ReadLastLine创建引擎，任何人都可以帮助我吗？ 我想你会想要一个示例exe，创建一个C＃应用程序， while(true){Console.WriteLine("bla");}就足够作为示例exe而不是我遇到麻烦的exe。 exe接管dos窗口并具有“旧学校界面”
async / await可以帮助….
await Exec(yourExe,parameters);
Task Exec(string exe,string args) { var tcs = new TaskCompletionSource
您需要处理回调事件以读取流：
startInfo.UseShellExecute = false; startInfo.CreateNoWindow = true; startInfo.RedirectStandardOutput = true; startInfo.RedirectStandardError = true; Process proc = new Process(); proc.StartInfo = startInfo; proc.ErrorDataReceived += new DataReceivedEventHandler(DataReceiveHandler); proc.OutputDataReceived += new DataReceivedEventHandler(DataReceiveHandler); proc.Start(); proc.BeginErrorReadLine(); proc.BeginOutputReadLine(); proc.WaitForExit();
