How Do I Exit a Windows Form Application?

I have a Windows Form Application that searches a directory for the existence of a file. If the file doesn't exist, I want to close the Application completely.

I tried using "Application.Exit()" from a function I created called "Init()", which searches for the file in question. I got an error message "ObjectDisposedExcetion was unhandled".

I replaced the "Application.Exit()" with a "Close()" call, but got the same error message.

Here's my code:

        private void Init()
        {
            bValidFile = true;
            strDataFileName = "aPIP.dat";
            strDataPath = Directory.GetCurrentDirectory() + "\\Data";
            MessageBox.Show(strDataPath);
            try
            {
                Directory.SetCurrentDirectory(strDataPath);
            }
            catch(DirectoryNotFoundException e)
            {
                MessageBox.Show("***ERROR***\nFile Not Found");
                bValidFile = false;                
            }
            if(!bValidFile)
            {
                Close();
//Application.Exit();
                

            }
        }
