C# OpenFileDialog Lock To Directory

Question

I am making a software that needs to ONLY be able allow people to select files and folders using the OpenFileDialog that are in the same directory as the program and that are in deeper folders. I don't want the OpenFileDialog to be able to select stuff outside of the program's current directory. Is this possible to do in C# using the OpenFileDialog?

Please let me know

Thanks

This is how I did it.

   openFileDialog1.InitialDirectory = Path.Combine(Path.GetDirectoryName(Application.StartupPath), "FolderName");

        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {            
                while(Path.GetDirectoryName(openFileDialog1.FileName) != Path.Combine(Path.GetDirectoryName(Application.StartupPath), "FolderName")){

                    MessageBox.Show("Please select .EXE which is in the default folder", "Wrong folder", MessageBoxButtons.OK, MessageBoxIcon.Information);
                openFileDialog1.ShowDialog();

            }                       
        }
