Question

我从一个循环调用rest API，我的对象名在运行时决定。我可以在这里使用反射作为一个对象，但如何获取对象列表？

  foreach (CloudDBTableList table in cloudDBTableList)
            {                
               string uri = string.Format(table.URI, "1-Jan-2011");
               string result  = _dataPullSvcAgent.GetData (baseURI + uri);


               string tableClassType = table.TableName + ", " + namespacePrefix;//namespacePrefix is same as assembly name.
               Type t = Type.GetType(tableClassType);
               JavaScriptSerializer jsonDeserializer = new JavaScriptSerializer();
//t is only type of object whereas below method returns List<t> how to put it?
               var objectList = jsonDeserializer.Deserialize(result, t);

            }
            return true;
        }

Stack Overflow Rocks。从这个问题找到答案（虽然下面的问题与我的有点不同）： -

How to dynamically create generic C# object using reflection? 我修改了我的代码： -

 foreach (CloudDBTableList table in cloudDBTableList)
            {                
               string uri = string.Format(table.URI, "1-Jan-2011");
               string result  = _dataPullSvcAgent.GetData (baseURI + uri);


               string tableClassType = namespacePrefix + "." + table.SchemaName + "." + table.TableName + ", " + namespacePrefix;//namespacePrefix is same as assembly name.
               Type t = Type.GetType(tableClassType);
               JavaScriptSerializer jsonDeserializer = new JavaScriptSerializer();
               var L1 = typeof(List<>);
               Type listOfT = L1.MakeGenericType(t);
               var objectList = jsonDeserializer.Deserialize(result, listOfT);


            }

你应该可以这样做：

JavaScriptSerializer jsonDeserializer = new JavaScriptSerializer();
List<CloudDBTableList > list= jsonDeserializer.Deserialize<List<CloudDBTableList>>(cloudDBTableList);

使用JavaScriptSerializer在C＃中反序列化通用对象的数组
