Form1 form

I need when open my application to check IF Excel file exist or not

IF Excel file not exist go to form CreateDatabase Form if excel file not exist

And

IF excel file database exist before open form1

How to do that please

in form1 load event i write following code

CreateDatabase frm = new CreateDatabase();
var fileName = string.Format("{0}\\Book3105.xlsx", Directory.GetCurrentDirectory());
if (!File.Exists(fileName))
{
Form1 frm1 = new Form1();
frm.Show();
frm1.Hide();
}
else
{
frm.Hide();
this.Show();
}

Accepted answer
Goto Program.cs from Solution explorer.
// Replace the line
// Application.Run (new Form1 ());

If (File.Exists (excelfile.xlsx))
   Application.Run (new Form1 ());
else
    Application.Run (new Form2 ());
Change your form accordingly.

Instead checking the file on form load event, it would be more convenient if you check file existence inside main method (under program.cs) then load appropriate form.
