private void button1_Click(object sender, EventArgs e)
    {
        string fileLoc = @"c:\wms.txt";

        if (File.Exists(fileLoc))
        {
            using (TextReader tr = new StreamReader(fileLoc))
            {
                MessageBox.Show(tr.ReadLine());
            }
        }
    }

This works perfectly in when I create a Windows Application.

When I use the same code in a Device application - Windows CE i get error:

Your device does not have a c drive. Replace

string fileLoc = @"c:\wms.txt";

with 

string fileLoc = @"wms.txt";

It seems that the root folder is automatically added to your path with a \

    Wouldn't you want the "\" still left in there, or else you will get a relative location? – gunr2171 Sep 30 '13 at 13:55

    @gunr2171 As far as I remember, Windows CE does not have a concept of "current directory" either, so all paths are automatically assumed to start at root, which means that `\\` is really optional. – Andrei Sep 30 '13 at 15:10

Windows CE does not have a concept of drive letters. Your path there should simply be @"\wms.txt".

try

string fileLoc = @"c:\wms.txt";

or 

string fileLoc = "c:\\wms.txt";

    Your first example is exactly what the OP tried, and the second is just another way to escape a backslash. – gunr2171 Sep 30 '13 at 15:13
