Craig,
You can get this information using the SHGetFileInfo (like your earlier post
states). Here is an example of how to get the File Description/type that you
are asking about. You should be able to copy and paste this into a C# Console
app. Just be sure that the first parameter to the SHGetFileInfo method is a
valid file.
I hope that this helps you out!

using System;
using System.Runtime.InteropServices;
namespace GetFileTypeAndDescription
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
SHFILEINFO shinfo = new SHFILEINFO();
IntPtr i = Win32.SHGetFileInfo(@"d:\temp\test.xls", 0, ref
shinfo,(uint)Marshal.SizeOf(shinfo),Win32.SHGFI_TY PENAME);
string s = Convert.ToString(shinfo.szTypeName.Trim());
Console.WriteLine(s);
}
}
[StructLayout(LayoutKind.Sequential)]
public struct SHFILEINFO
{
public IntPtr hIcon;
public IntPtr iIcon;
public uint dwAttributes;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]
public string szDisplayName;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 80)]
public string szTypeName;
};
class Win32
{
public const uint SHGFI_DISPLAYNAME = 0x00000200;
public const uint SHGFI_TYPENAME = 0x400;
public const uint SHGFI_ICON = 0x100;
public const uint SHGFI_LARGEICON = 0x0; // 'Large icon
public const uint SHGFI_SMALLICON = 0x1; // 'Small icon
[DllImport("shell32.dll")]
public static extern IntPtr SHGetFileInfo(string pszPath, uint
dwFileAttributes, ref SHFILEINFO psfi, uint cbSizeFileInfo, uint uFlags);
}
}
