I am getting an error message and I have not been able to figure hot
how to fix it. I have done some research with no answers yet.

I found this code that may help? Not sure what to do with it.
using (StreamWriter sw = new StreamWriter (fullAddress , false,
Encoding.UTF7))


Error message::::::::::::::::::::::::::::::::::::::::::::::
Code:
Compilation Error

an assembly reference?)

StreamWriter(@"G:\Inetpub\wwwroot\csf\Tutorials\Exec\fileIO.txt",true);

//This will append the given input to the file since arg2 is true
sw.Write("I love C# and I don't care who knows it!~~" + "<br>");

//Cleanup
sw.Close();

StreamWriter is part of System.IO, so you need a reference to it.

Try putting

using System.IO;

at the top of your code.

HTH,

rex64,

The reason for this is that you are using the shorthand for the
StreamWriter class, and you don't have the appropriate imports statement at
the top. What you want to do is place this at the top of your page:

<%@ Import namespace="System.IO" %>

And it should work.

Hope this helps.
