JQuery扩展提交JSON数据 

 1 $.fn.extend({
 2     // $(that).children() 只读取 id 以 "json_" 开始的元素,
 3     // 且 id 的命名规则一定是 json_[id]_[dataType]
 4     // [id] 是不能包含 _ 的任何有意义的名称
 5     // [dataType] 是该元素的数据类型,根据 c# 的基本数据类型命名,用途待续...
 6     toSubmitJSON: function (url) {
 7 
 8         var that = this;
 9         var elementIdPattern = /^json_[a-zA-Z0-9]+_[a-z]+$/;  //!important
10 
11         var jsonEntity = function (elementId, elementValue) {
12             var splitFrom = elementId.split("_");
13             this.id = splitFrom[1];
14             this.dataType = splitFrom[2];
15             this.value = elementValue;
16             this.toJSONString = function () {
17                 return '{"id":"' + this.id + '","dataType":"' + this.dataType + '","value":"' + this.value + '"}';
18             };

21         var getJSONData = function () {
22             var jsonBuilder = "";
23             var child = $(that).children();
24             child.each(function (index) {

42                 jsonBuilder = "[" + jsonBuilder + "]";
43             }
44             return jsonBuilder;
45         }
46

48         var jsondata = getJSONData();

50             alert("missing json data element.");
51         }
52         else {
53             $.ajax({
54                 url: url,
55                 type: "POST",
56                 dataType: "json",
57                 contentType: "application/json",
58                 data: jsondata,
59                 cache: false,
60                 error: function (jqXHR) {
61                     alert(jqXHR.statusText);
62                 },
63                 success: function (data) {
64                     alert(data);

66                 complete: function () {
67                     alert("complete");
68                 }
69             });
70         }
71     }
72 });


结合 Newtonsoft.json 获取数据

public ActionResult JsonData(){
            string json = new System.IO.StreamReader(this.HttpContext.Request.InputStream).ReadToEnd();

            var result=Newtonsoft.Json.JsonConvert.DeserializeObject(json);

            return Json(result.ToString());
}

    ViewBag.Title = "Index";
