How to execute this command in cmd prompt using C#

Hello!

I am trying to execute a command in cmd.exe using C#.

Normally, I would open the cmd.exe prompt manually and I would go the the directory: "C:\myproject" which is the directory I need to first select.

Secondly, I would manually run the command: "node fileWithCommands.js" which is a ".js" file which exists in the "C:\myproject" directory. I would then VISUALLY see commands executing in the actual cmd window that is opened.

So now I am trying to emulate this above manual task by executing that using C#. But the cmd window is only opening with "C:\myproject" selected and the below command is not executing?

Thank you!

Code not executing?

p.StartInfo.Arguments = "node fileWithCommands.js";

Complete code:

            Process p = new Process();
            p.StartInfo.FileName = "C:\\Windows\\system32\\cmd.exe";
            p.StartInfo.WorkingDirectory = @"C:\myproject";
            p.StartInfo.Arguments = "node fileWithCommands.js";
            p.Start();

    Try the following

    var p = new Process  
    {  
        StartInfo =  
        {  
            FileName = "node",   
            WorkingDirectory = @"C:\myproject",   
            Arguments = "fileWithCommands.js"  
        }  
    };
