Question

I have a dot net MVC 4 application in which I user creates a request using “create” view and based on the params from view, the controller should execute windows batch scripts asynchronously.

I’m using following code to run the batch script:

Process process = new Process();

ProcessStartInfo ProcessInfo;
ProcessInfo = new ProcessStartInfo("cmd", "/c  batchfile");
ProcessInfo.CreateNoWindow = true;
ProcessInfo.UseShellExecute = false;
ProcessInfo.RedirectStandardError = true;
ProcessInfo.RedirectStandardOutput = true;
ProcessInfo.Arguments = string.Format("{0} {1} {2}", arg1, arg2, arg3); ;

process = Process.Start(ProcessInfo);
process.WaitForExit();

The console app process is started but it always hangs/waits endlessly. The standard output logs show:

Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.

C:\Program Files (x86)\IIS Express>

The process exits only when I manually kill it. I tried running Visual Studio administrator mode but it didn’t help.

Can anyone please suggest how I can get around this?

Here’s a reference article about command line parameters passed to cmd.exe I would recommend you checking.

Then try like this:

var psi = new ProcessStartInfo("cmd.exe")
{
    Arguments = string.Format("/k \"\"batchfile.bat\" \"{0}\" \"{1}\" \"{2}\"\"", arg1, arg2, arg3),
    CreateNoWindow = true,
    UseShellExecute = false,
    RedirectStandardError = true,
    RedirectStandardOutput = true
};

using (var process = Process.Start(psi))
{
    process.WaitForExit();
}
