reference a windows shell interface using .net 4.0

Question

I am using the following code to reference a shell dll

            Type t = Type.GetTypeFromProgID(\"Shell.Application\");

            Shell s = (Shell)Acti         


        

Answer 1

Instead of

Type t = Type.GetTypeFromProgID("Shell.Application");

dynamic shell = Activator.CreateInstance(t);

I used

var shell = (IShellDispatch4) new Shell();

shell.Namespace then works as expected.

Turns out that reference for a shell object defaults to IShellDispatch5, which can't be used in XP or 2003.

Answer 2

Ok,this is how I got through the problem incase it helps someone

This is how my new code looks like

Type t = Type.GetTypeFromProgID("Shell.Application");

dynamic shell = Activator.CreateInstance(t);

//This is browse through all the items in the folder
var objFolder = shell.NameSpace(@"\\fileshares\Files\test");

foreach (var item in objFolder.Items())
{
    //This is to get the file's comments for each files in the folderitem

    string file_version = objFolder.GetDetailsOf(item, 14).ToString();

     Console.WriteLine(file_version);

}
