Question

How to get an exit code from an application. Example: I call: System.Diagnostic.Start(“regsvr32”, “mydll.dll”); How to get an exit code from regsvr32?

And how to write an application which returns an exit code (like regsvr32). Thanks.

I’am using .NET 4.0 & C#.

This is actually two separate questions, but… The exit code is the value returned from the program’s Main function. So:

public static int Main()
{
    // code

    return 0;
}

Will return an exit code of 0. Unless the preceding // code does something different.

Use the Process’ ExitCode property to get this value from the application to execute.

0 is typically returned when the program succeeds. Anything else is a failure but this is a matter of interpretation.
