string file path is not working c#

Okay I have spent an inordinate amount of time trying to solve what the posts i've read say is a simple fix.

I want to write to a file in my documents and here is my code.

        string st = @"C:\Users\<NAME>\Documents\Sample1.txt";

        System.IO.StreamWriter file = new System.IO.StreamWriter(st);
        file.WriteLine(Convert.ToString(Sample1[0]));
        file.Close();

Where is the user name. I am getting the following error

"A first chance exception of type 'System.IO.DirectoryNotFoundException' occurred in mscorlib.ni.dll. An exception of type 'System.IO.DirectoryNotFoundException' occurred in mscorlib.ni.dll but was not handled in user code"

I am using Visual Studio Express for Windows Phone Development.

If anyone can point out what i am doing wrong i would be grateful.

Thanks.

To get MyDocuments use:

    Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)

This will return the path to MyDocuments on the host computer.

You can see a list of SpecialFolders on MSDN: http://msdn.microsoft.com/en-us/library/system.environment.specialfolder.aspx

EDIT: I just noticed you were developing for Windows Phone. Read up on the other SpecialFolders on MSDN.

You should take advantage of the Environment.SpecialFolder enumeration and use Path.Combine(...) to create a path:

var path = Path.Combine(
    Environment.GetFolderPath(Environment.SpecialFolder.Personal),
    "Sample1.txt");

using (var sw = new StreamWriter(path))
{
    sw.WriteLine(Convert.ToString(Sample1[0]));
}

Also, StreamWriter should be placed within a using statement since it is disposable.

I assuming you're using the string as you've posted it. If thats the case you should use the SpecialFolder Enum instead.

var st = string.format(@"{0}\Sample1.txt", 
             Environment.GetFolderPath(Environment.SpecialFolder.Personal));
