Determining if file exists

[dannytan]

hi all. i am currently writing a simple program. in my program, before the form loads, i would need to determine if a file named "abc.mdb" exists in the current directory of the running program. so below is what i did:

		private void MainFrm_Load(object sender, System.EventArgs e)
		{
			string curDir = Directory.GetCurrentDirectory();
			FileInfo fi = new FileInfo(curDir+"\\Abc.Mdb");
			string fp = fi.FullName;
            
			if(fi.Exists == false)
			{
				MessageBox.Show("System file Abc.Mdb is not found.", "File not found", MessageBoxButtons.OK, MessageBoxIcon.Error);
				Application.Exit();
			}
			else
			{
			}
		}

The problem is that EVEN the file EXISTS in the current directory fi.Exists is still false. Can anyone help? Thanks.
