Hi,

Ofcourse that will not work as you are passing typed value in list.

Instead use below code,

C#

List<dynamic> _PhysicalResult = new List<dynamic>();
_PhysicalResult.AddRange(_contacts);

Above code will work if you are using Framework 4.0.

If you want it in older version then you can use List<object> instead List<dynamic>

Thanks
