推荐答案

当然，当您在列表中传递键入的值时，它将不起作用.

而是使用下面的代码，

Hi,

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

Instead use below code,

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

如果您使用Framework 4.0，则上面的代码将起作用.

如果您希望使用旧版本，则可以使用 List< object> 代替 List< dynamic>

谢谢

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
