Process ExitCode 1 for batch file execution from C#

[Zeya]

I have created a very simple batch file and trying to retrieve the
standard output but everytime I run the code it returns ExitCode as 1.

I have created a batch file as simple as ping localhost or echo hello
world and neither have worked. Note: This is from ASP.Net code. Also,
the batch file runs just fine from command line.

I am running another Exe process with arguments from the same method
and that runs just fine too.

Am I missing on something?

Here is the code:
Calling code:

ExecuteProcess( Server.MapPath( pathofbatchfile ), string.Empty, null,
null, out OutputVal );


Method implementation:

public static int ExecuteProcess ( string ProcessName, string
ProcessArguments, NameValueCollection Variables, string
WorkingDirectory ,out string Log )
{
//Clear log.
Log = "";
using ( Process DOSProcess = new Process() )
{
ProcessStartInfo StartInfo = new ProcessStartInfo();

StartInfo.FileName = ProcessName;

if ( Variables != null )
{
foreach( string Key in Variables.Keys )
{
StartInfo.EnvironmentVariables.Add( Key, Variables[ Key ] );
}
}

StartInfo.RedirectStandardError = false;
StartInfo.RedirectStandardOutput = true;
StartInfo.RedirectStandardInput = false;

StartInfo.UseShellExecute = false;
StartInfo.CreateNoWindow = true;

if ( ProcessArguments != string.Empty & ProcessArguments != null )
StartInfo.Arguments = ProcessArguments;

if ( WorkingDirectory != string.Empty & WorkingDirectory != null )
StartInfo.WorkingDirectory = WorkingDirectory;

DOSProcess.EnableRaisingEvents = true;

DOSProcess.StartInfo = StartInfo;

DOSProcess.Start();

do
{
Log += DOSProcess.StandardOutput.ReadToEnd();
}
while ( !DOSProcess.HasExited );

int ProcessExitCode = DOSProcess.ExitCode ;

return ProcessExitCode;
}

}

Hi,

I'm having a similar problem. Did you find a solution?

 

[Zeya]

Yes.

Set Shell execute to true.

StartInfo.UseShellExecute = true;

This MAY stop standard output.

HTH.

It didn't work for me. Thanks anyway I'll try to send a new post with the
specific problem.
