Question

我正在为控制台程序制作GUI。有时需要输入密码，因此如果输出包含“密码”，则会打开一个对话框。

问题是输出不会打印“输入密码”这一行，而是会运行控制台。

打开...
  阅读配置......
  输入您的密码：＆lt; - 它出现在控制台中，但不出现在GUI中。

过程：

this.ASFProcess.StartInfo.Arguments = "--server";
this.ASFProcess.StartInfo.CreateNoWindow = true;
this.ASFProcess.StartInfo.Domain = "";
this.ASFProcess.StartInfo.FileName = "ASF.exe";
this.ASFProcess.StartInfo.LoadUserProfile = false;
this.ASFProcess.StartInfo.Password = null;
this.ASFProcess.StartInfo.RedirectStandardError = true;
this.ASFProcess.StartInfo.RedirectStandardInput = true;
this.ASFProcess.StartInfo.RedirectStandardOutput = true;
this.ASFProcess.StartInfo.StandardErrorEncoding = null;
this.ASFProcess.StartInfo.StandardOutputEncoding = null;
this.ASFProcess.StartInfo.UserName = "";
this.ASFProcess.StartInfo.UseShellExecute = false;
this.ASFProcess.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
this.ASFProcess.SynchronizingObject = this;
this.ASFProcess.OutputDataReceived += new System.Diagnostics.DataReceivedEventHandler(this.ASFProcess_OutputDataReceived);
this.ASFProcess.ErrorDataReceived += new System.Diagnostics.DataReceivedEventHandler(this.ASFProcess_ErrorDataReceived);

方法：

private void BackgroundWorker_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    ASFProcess.Start();
    ASFProcess.BeginOutputReadLine();
    ASFProcess.BeginErrorReadLine();
    ASFProcess.WaitForExit();
}

private void ASFProcess_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
    rtbOutput.AppendText(e.Data + Environment.NewLine);
    rtbOutput.SelectionStart = rtbOutput.Text.Length;
    rtbOutput.ScrollToCaret();
    if (e.Data.Contains("password"))
    {
        var enterPassword = new EnterPassword();
        enterPassword.ShowDialog();
    }
}

根据这个：https://msdn.microsoft.com/en-us/library/system.diagnostics.process.outputdatareceived(v=vs.110).aspx

OutputDataReceived事件表示关联的进程具有   写了一个

行，以换行符结尾，重定向   StandardOutput流。

所以我建议ASF.exe程序的问题在于它提示输入密码的行，它在预期输入之前没有发送换行符。

我建议改变你的ASF程序的工作方式，或尝试阅读标准版和标准版。错误输出以另一种方式输出。

进程输出不写最后一行
