exit application error

I developed a simple windows application on .NET 4. I'd like to pass a parameter to my application and if this parameter was empty the application should not continue running and quit.

I add an input parameter in the main method. It works fine when I debug it in my Visual Studio but when I execute my application directly Windows gave me this error:

"application has stopped working"

How can i handle it? I tested some codes but it doesn't work

 Application.ExitThread();
 Application.Exit();

This is may main method:

 [STAThread]
 static void Main(string[] args)
 {
     if(args.Count()==0)
      Thread.CurrentThread.Abort(); 

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.Run(new Form1());
 }

I looked at Windows Event Viewer and found this error events

Application: WindowsFormsApplication1.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Threading.ThreadAbortException
Stack:

I don't get the reason for your code above.

if this parameter was empty application do not continue running and exit works.

You could easily code in this way

 [STAThread]
 static void Main(string[] args)
 {
     if(args.Length > 0)
     {

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.Run(new Form1());
     }
 }

I would expect this with the code you have supplied. Calling Thread.Abort() raises an exception on the thread (ThreadAbortException, which will be uncaught).

If all you want to do is stop processing with no arguments, simply return:

[STAThread]
 static void Main(string[] args)
 {
     if(args.Length ==0) return; // Will leave and end the application

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.Run(new Form1());
 }

You also are using Count() on the array when Length will simply do. Minor detail though.
