How to Serialize a Dictionary<string,string> and not surround the value with quotes?

由 假装没事ソ 提交于 2019-12-07 14:06:29
Example model: public class Thing { [JsonProperty("foo")] public string Foo {get;set;} [JsonProperty("bars")] public Dictionary<string,string> Bars {get;set;} } i want the output to look like this: {"foo":"Foo Value", "bars":{"key1":key1Value,"key2":key2Value}} The reason I want the values of the Dictionary to be without quotes is so I can pull the value from the client via jquery: {"foo":"Foo Value", "bars":{"key1":$('#key1').val(),"key2":$('#key2').val()}} Is this possible using Json.Net?

由 拟墨画扇 提交于 2019-12-07 09:25:05
问题 I have a question on a MVC4 (beta) issue I have been struggling with for some time now. The issue is that I want to create a json with the object name added for my webapi.

I tried searching on the subject, but as MVC4 is still in beta it's difficult to find good info on this subject. I have already imported the JSON.NET formatter in my solution, but this does not add
