NOT creating new .txt file

[Toboe]

I have a slight problem. The idea with this part is that the program open a .txt file witch name you type in. It works. The problem is, if you type in a name of file that does not exist, it still opens notepad and ask if I want to create a new document with the name you gave. If the file does not exist, a message box or something similar should show up. Please advice. Thanks :)

private void button3_Click(object sender, EventArgs e)
        {
            if (TextBox1.Text != "")
            {
                try
                {
                    System.Diagnostics.Process.Start("notepad.exe", TextBox1.Text);
                }
                catch (Exception excep)
                {
                    MessageBox.Show(excep.ToString());
                }
             }

Try using the System.IO.File.Exists method to see if the file does exist before starting the process.

Check to see if the file exists before you try to pass it off to Notepad.

System.IO.File.Exists(string PathToFile)
