C# - 捕获 Windows 应用程序输出
我的应用程序启动“C:\Windows\System32\Msra.Exe”来控制域计算机。有没有办法捕获此 msra.Exe 显示的错误消息。 （即来自 msra.exe 的内部错误消息，而不是来自我的应用程序的错误消息。） 该应用程序本身是一个 Windows 窗体应用程序。
任何帮助表示赞赏。
启动 MSRA 的代码如下...它只是完整应用程序的一个片段。
string msra = "C:\\Windows\\System32\\runas.exe";
string domainname = "**********";
string domaincontroller = "*************";
if (File.Exists(msra) == false)
{
System.Windows.Forms.MessageBox.Show("Runas.exe not found.\n\rPlease contact your internal IT support.", "Fatal Error", System.Windows.Forms.MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Error);
}
else
{
try
{
Process p = new Process();
p.StartInfo.UseShellExecute = true;
p.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
p.StartInfo.ErrorDialog = true;
p.StartInfo.FileName = msra;
p.StartInfo.Arguments = "/noprofile /netonly /user:" + domainname + "\\" + username + " \"cmd /server:" + domaincontroller + " /C msra.exe /offerra " + computerip + "\"";
p.Start();
p.Dispose();
Thread.Sleep(1700);
SendKeys.SendWait(password);
SendKeys.SendWait("{ENTER}");
}
catch
{
System.Windows.Forms.MessageBox.Show("MSRA could not be started for an unknown reason");
}
}
My application launches "C:\Windows\System32\Msra.Exe" to control a domaincomputer. Is there a way I can capture the error messages that this msra.Exe shows. (I.e. internal error messages from the msra.exe and not the ones from my app.)
The app itself is a windows Forms app.
Any help is appreciated.
The Code to start MSRA is below... it is just a snippet of the complete application.
string msra = "C:\\Windows\\System32\\runas.exe";
string domainname = "**********";
string domaincontroller = "*************";
if (File.Exists(msra) == false)
{
System.Windows.Forms.MessageBox.Show("Runas.exe not found.\n\rPlease contact your internal IT support.", "Fatal Error", System.Windows.Forms.MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Error);
}
else
{
try
{
Process p = new Process();
p.StartInfo.UseShellExecute = true;
p.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
p.StartInfo.ErrorDialog = true;
p.StartInfo.FileName = msra;
p.StartInfo.Arguments = "/noprofile /netonly /user:" + domainname + "\\" + username + " \"cmd /server:" + domaincontroller + " /C msra.exe /offerra " + computerip + "\"";
p.Start();
p.Dispose();
Thread.Sleep(1700);
SendKeys.SendWait(password);
SendKeys.SendWait("{ENTER}");
}
catch
{
System.Windows.Forms.MessageBox.Show("MSRA could not be started for an unknown reason");
}
}

您可以将
RedirectStandardOutput或RedirectStandardError设置为true以便能够从进程的标准输出或错误输出中读取。然后，您可以选择如何实际读取数据：
StandardOutput属性OutputDataReceived事件并调用BeginOutputReadLine()或相应的成员对于错误流。
You can set
RedirectStandardOutputorRedirectStandardErrortotrueto be able to read from the standard output or error output of the process.You then have several options how to actually read the data:
StandardOutputpropertyOutputDataReceivedevent and callBeginOutputReadLine()Or the corresponding members for the error stream.

您正在使用 Process，因此请尝试 Process.StandardError 属性。您为其分配一个流并且您将能够使用它。

当您在那里时，您还可以使用 Process.StandardOutput

You are using Process so try the Process.StandardError property. You assign it a stream and you will be able to use it.
http://msdn.microsoft.com/en-us/library/system.diagnostics.process.standarderror.aspx
And while you're there you can also use Process.StandardOutput
