How to Write/Read a Text File in windows mobile emulator?

Hi,
In windows mobile file path as "\\Program Files\\Projectname\\filename "(ex:"Program Files\\jsonstringpra\\jsonstring.txt"). I add a text file jsonstring to my project and select file and property ser as Copy if newer.
just look at my code:

StreamReader resposeStream = new StreamReader("Program Files\\jsonstringpra\\jsonstring.txt");
parsingstring = resposeStream.ReadToEnd();
label5.Text = parsingstring;

it excutes correctly.
