JavaScriptSerializer c# 反序列化的时候报错“ 没有为类型“System.String”定义无参数的构造函数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.Web.Script.Serialization;
using System.Runtime.Serialization;

namespace HLSX.Jason
{

//[Serializable]
public class ResultData
{


    public ResultData()
    {

    }
    public ResultData(int res, string strda)
    {
        result = res;
        data = strda;
    }
    public int result { get; set; }
    public string data { get; set; }
}
class DealJson{
   // ResultData rsData;
    public  static int getResult( string strJson )
    {
        ResultData rsData = new ResultData();

        JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();

        rsData = jsonSerializer.Deserialize<ResultData>(strJson);

        return rsData.result;

    }

    public static string getData(string strJson)
    {
        ResultData rsData = new ResultData();

        rsData.result = -2;
        rsData.data = string.Empty;

        JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();

          rsData = jsonSerializer.Deserialize<ResultData>(strJson);【此行报错】

        return rsData.data;

    }
}

}
