asp.net – JSON.NET读取JObject时出错

导读：我通过 AJAX和Web Api将 JSON对象发送到我的服务器： var data = [ ["fdsfsd","Kifdsfa","fsdfsa","fadsf","fasdfsd","fasdfsd"],["2008","-5","11","12","13"],["2009","20","-11","14",["2010","30","15","-12","readOnly"]];$.ajax({ url: '../webapi/Pro

我通过 AJAX和Web Api将 JSON对象发送到我的服务器：

var data = [
  ["fdsfsd","Kifdsfa","fsdfsa","fadsf","fasdfsd","fasdfsd"],["2008","-5","11","12","13"],["2009","20","-11","14",["2010","30","15","-12","readOnly"]
];

$.ajax({
        url: '../webapi/Products',type: 'POST',dataType: "text",data: "="+JSON.stringify( data ),success: function (test) {
                alert(test);
            },error: function (test) {
                alert("Error");
            }

所以我在服务器上获得了我想用JSON.NET解析的值：

public void Post([FromBody]string value )
{
      JObject o = JObject.Parse(@value);
}

这引发了异常：

Error reading JObject from JsonReader. Current JsonReader item is not an object:
StartArray. Path '',line 1,position 1.

为什么？价值似乎对我来说是对的？

解决方法

json.stringify将创建以下json字符串：

[
  ["fdsfsd","readOnly"]
]

哪个是jsonArray而不是JsonObject.所以在服务器端你必须使用JArray a = JArray.Parse(@value)读取它;
