当我传递数组到WebMethod与字典

Answer 1

如果它是一个webap的web方法然后，我不能将列表或字典类型的对象传递给方法，只会传递字符串参数，传递此对象以将它们序列化为字符串，然后将其反序列化为列表或字典对象那个字符串。

WEBMETHOD消耗代码：

Dictionary<string,int> objstring = new Dictionary<string,int> 
var serializer = new JavaScriptSerializer(); 
var serializedstring = serializer.Serialize(objstring); 

，然后通过在参数的serializedstring。

做同样的反序列化只是从webapi方法中的序列化对象调用deserialize方法。

我希望这可以帮助你。
