When I try to databind an ASP.NET GridView to an IEnumerable<ExpandoObject> using an ObjectDataSource, I get the following exception.

推荐答案

开源框架 Impromptu-Interface 可以做到这一点。它具有通过传入属性名称 - >类型的字典来暴露用于反射的动态对象属性的方法。

The opensource framework Impromptu-Interface can do this. It has a method for exposing dynamic object properties for reflection by passing in a dictionary of property names->types.

IEnumerable<dynamic> tProxiedObject = listOfExpandos.Select(x=>Impromptu.ActLikeProperties(x, x.ToDictionary(k=>k.Key,v=>typeof(object))));
