I got a program that writes some data to a file using a method like the one below.

```

public void ExportToFile(string filename)
{
     using(FileStream fstream = new FileStream(filename,FileMode.Create))
     using (TextWriter writer = new StreamWriter(fstream))
     {
         // try catch block for write permissions 
         writer.WriteLine(text);

     }
}

```

When running the program I get an error:

> 
> Unhandled Exception: System.UnauthorizedAccessException: Access to the path 'mypath' is denied.
>  at System.IO.\_\_Error.WinIOError(Int32 errorCode, String maybeFullPath)
>  at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access,

>  FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolea
>  bFromProxy)
>

Question: What code do I need to catch this and how do I grant the access?
