Close the application before loading the form.

I have a program in which I will check if a file exists. If this happens, the form will load. But if not, a message appears informing the user, and then the application should close without showing the form.

How do I do it right? I tried using this code in the constructor:

    Environment.Exit(-1);

He does what I want, but from what I read, this is not a good way to do this. It's right? Or I'll just use the code above.

You do not need to name anything if you put your check before starting the main form application

    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        // Check for file 
        if(!File.Exists("your file to check))             
        {
            MessageBox.Show(.....)
        }
        else
        {
            Application.Run(new frmMain());
        }
    }

Try using this:

yourForm.close();

Or simply do not call the form until you are sure that the file does not exist.

Try the following: a little easier (I think I understood you correctly)

if (File.Exists("somefile.txt"))
{
   //do your operation
}
else
{
    this.Close();
}
