问题描述

好吧，所以我运行了一个打开.bat的程序，读取了它的输出，显示了它，并通过winform获得了给定的输入

Ok so im running a program that opens a .bat, reads its output, displays it and gets given input by the winform

这是我的代码:

      Process p = new Process();
        private void button1_Click(object sender, EventArgs e)
        {

 
  
            p.StartInfo.FileName = @"run.bat";

            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;
            p.EnableRaisingEvents = true;

            p.OutputDataReceived += new DataReceivedEventHandler(p_OutputDataReceived);
            p.Exited += new EventHandler(p_Exited);
            p.Start();
            p.BeginOutputReadLine();
        }




        void p_Exited(object sender, EventArgs e)
        {
            if (this.InvokeRequired)
            {
                Invoke(new EventHandler(p_Exited), new object[] { sender, e });
                return;
            }
            textBox1.Text += "Server Has Shutdown Sucessfully ";
        }

        void p_OutputDataReceived(object sender, DataReceivedEventArgs e)
        {
            if (this.InvokeRequired)
            {
                Invoke(new DataReceivedEventHandler(p_OutputDataReceived), new object[] { sender, e });
                return;
            }
            textBox1.Text += (e.Data ?? string.Empty) + Environment.NewLine;
            textBox1.SelectionStart = textBox1.Text.Length;
            textBox1.ScrollToCaret();    

        }

    



    



     



        private void button2_Click(object sender, EventArgs e)
        {
            p.StandardInput.WriteLine("shutdown");
            p.Close();


        }


    }
}

我遇到的第一个问题是读取输出仅给我3行，然后连续给我:

First problem i get is the read output only gives me 3 lines then it continually gives me this: 

>

>

>

> 

> 

ect .. 

ect..  

第二个问题，我尝试按我的停止"按钮，然后按注视的按钮(有效地重新启动)

Second problem, i try to press my stop button and then the stard button (effectivly re starting)

我收到此错误:

异步读取操作已在流上开始."

"An async read operation has already been started on the stream."

第三我想知道如何将textBox4的文本发送到正在运行的.bat

3rd   I would like to know how i could get textBox4's Text to the .bat that im running

类似的东西应该可以正常工作:

something like this should work right:

   private void textBox4_TextChanged(object sender, EventArgs e)
        {
if (keydown == enter) {

            p.StandardInput.WriteLine(textBox4.Text);

}
        }

任何代码，摘要或帮助都将不胜感激

Any code, snippets or help would be much appreciated

推荐答案

它在

It says in the documentation for Process.OutputDataReceived Event that:

正在处理异步输出的应用程序应调用 WaitForExit 方法，以确保已清除输出缓冲区.

The application that is processing the asynchronous output should call the WaitForExit method to ensure that the output buffer has been flushed.

有一个 这里有个合理的例子.  请注意，它将调用WaitForExit.

There's a reasonable example here.  Note that it calls WaitForExit.
