请求正文列表 <KeyValuePair<string,string> &gt;

Question

I have WebService with the following method's:

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
string PostList(List<string> arr);

The RequestBody of the method is:

{"arr" : ["somestring1", "somestring2"]}

Now, I want another web method like that:

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
string PostListKVP(List<KeyValuePair<string, string>> arr);

How does the JSON RequestBody should be for this WebMethod?

Thanks.

As @Dmytro Shevchenko suggest i replace to Dictionary<string,string> like the follow:

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
string PostDictionary(Dictionary<string, string> arr);

And the requestbody is:

{"str" : [{"Key":1,"Value":2},{"Key":2,"Value":3}]}
