我收到此错误

在解析值

意外遇到性格：S.路径'，行0，0

解决方案

信息是JSON对象没有列出。您必须具有集成串行器或手动操作序列化JSON对象。
我想那一定是这样的：

 公众的ActionResult动作（对象消息）
{
    // deserialise如果对象消息是一个字符串
    VAR串行=新的JavaScriptSerializer（）;
    变种C = serializer.Deserialize＆LT; YourClass＆GT;（消息）;    // deserialise如果对象消息是一个JSONObject
    VAR串行=新DataContractJsonSerializer（typeof运算（YourClass））;
    变种C =（YourClass）serializer.ReadObject（消息）;    返回PartialView（消息）;
}
 

或另一种解决方案：

我使用的库 Newtonsoft.Json 。如果你想在你的情况下使用它，它看起来像：

  ...
MyClass的M = JsonConvert.DeserializeObject＆LT;消息＆GT;（message.ToString（））;
VAR状态= m.Status; //...等等

View Model

public class EbayEarnings_Temp
{
    public String Program { get; set; }
    public DateTime Date { get; set; }
    public DateTime TimePlus { get; set; }
    public String Campaign { get; set; }
    public int Clicks { get; set; }
    public decimal EPC { get; set; }
    public decimal Earnings { get; set; }
    public String CampaignID { get; set; }
    public String Impression { get; set; }
    public string Status { get; set; }
}

var serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(typeof(EbayEarnings_Temp));
var c = (EbayEarnings_Temp)serializer.ReadObject(jsonString);

I am getting this error

Unexpected character encountered while parsing value: S. Path '', line 0, position 0.

解决方案

Message is json object not list. You must have integrated serializer or serialize json object in action manually. I think it must look like this:

public ActionResult action(Object Message)
{    
    // deserialise if Object Message is a string
    var serializer = new JavaScriptSerializer();
    var c = serializer.Deserialize<YourClass>(Message);

    // deserialise if Object Message is a JsonObject
    var serializer = new DataContractJsonSerializer(typeof(YourClass));
    var c = (YourClass)serializer.ReadObject(Message);

    return PartialView(Message);
}

or another solution:

I use library Newtonsoft.Json. If you're going to use it in your case it would look like:

...    
MyClass m = JsonConvert.DeserializeObject<Message>(message.ToString());
var status = m.Status; //...and so on
