Problem executing a simple command line statement using C#

Hi,

I am using Windows7 system and if I go to Command line and run the following command, it works fine.
C:\WINDOWS\System32\MSG [windowsusername] "Hello"

Open in new window

So, I thought of executing the same statement from a C# program and copied this code from Internet.
            System.Diagnostics.Process process = new System.Diagnostics.Process();

            System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
            startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
            startInfo.FileName = "cmd.exe";
            startInfo.Arguments = @" /C MSG Amit.Jain Hello"; 
            process.StartInfo = startInfo;
            process.Start();
            process.WaitForExit(100);
            process.Close();
            process.Dispose();

Open in new window

When I run the above code, unfortunately nothing happens. Does anyone have any idea what is going wrong here?

Thanks in advance.

What are you expecting to see happen? Currently you have the command window style set to System.Diagnostics.ProcessWindowStyle.Hidden which means you won't see anything on screen as the window is hidden.

Secondly, you will probably need to quote the arguments. So:
 startInfo.Arguments = @" /C MSG Amit.Jain Hello"; 

Open in new window

Should be:
 startInfo.Arguments = @" /C MSG Amit.Jain \"Hello\""; 

Open in new window

On my system, I had to switch the "Platform Target" to "x64" in Project --> Properties --> Build for it to work.  Then your code worked with no changes at all.

Carl, I changed ProcessWindowStyle.Hidden to ProcessWindowStyle.Normal and used
startInfo.Arguments = @" /C MSG Amit.Jain \"Hello\"";

Open in new window

but that did not work.

And Mike, just changing the Project Properties "Platform Target" to x64 worked like a charm. Thanks a lot.
