I am trying to use Shell32 to get extended file properties in c#.
My code for this is as follows.
var file = FileUpload1.PostedFile;
List<string> arrHeaders = new List<string>();
Shell shell = new ShellClass();
//Exception is thrown at next line
Folder rFolder = shell.NameSpace(Path.GetDirectoryName(file.FileName));
FolderItem rFiles = rFolder.ParseName(Path.GetFileName(file.FileName));
for (int i = 0; i < short.MaxValue; i++)
{
string value = rFolder.GetDetailsOf(rFiles, i).Trim();
arrHeaders.Add(value);
}
I am getting exception as follows.
Message - Unable to cast COM object of type 'Shell32.ShellClass' to interface type 'Shell32.IShellDispatch6'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{286E6F1B-7113-4355-9562-96B7E9D64C54}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

How to fix this?
Thanks.
