JSON格式转换-创新互联

引用：System.ServiceModel.Web程序集（系统内置）

public static T JSONDecode(string json)
{
    JsonQueryStringConverter converter= new JsonQueryStringConverter();
return (T) converter.ConvertStringToValue(json, typeof(T));
}

public static string JSONEncode(T obj)
{
    JsonQueryStringConverter converter= new JsonQueryStringConverter();
return converter.ConvertValueToString(obj, typeof(T));
}

引用：System.Text.RegularExpressions; System.Runtime.Serialization.Json;

public static string ObjectToJson(T t)
        {
using (MemoryStream ms = new MemoryStream())
            {
                DataContractJsonSerializer serializer= new DataContractJsonSerializer(typeof(T));
                serializer.WriteObject(ms, t);
                ms.Position= 0;
using (StreamReader reader = new StreamReader(ms))
                {
string json = reader.ReadToEnd();
string p = @"\/Date((d+)+d+)\/";
                    MatchEvaluator evaluator= new MatchEvaluator(ConvertJsonDataToDataString);
                    Regex reg= new Regex(p);
                    json= reg.Replace(json, evaluator);
return json;
                }
            }

        }

public static T JsonToObject(string json)
        {
string p = @"d{4}-d{2}-d{2}sd{2}:d{2}:d{2}";
            MatchEvaluator evaluator= new MatchEvaluator(ConvertDateStringToJsonDate);  //对时间进行处理            Regex reg = new Regex(p);
            json= reg.Replace(json, evaluator);
using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
            {
                DataContractJsonSerializer serializer= new DataContractJsonSerializer(typeof(T));
                JsonQueryStringConverter json1= new JsonQueryStringConverter();

                T data= (T)serializer.ReadObject(ms);
return data;
            }
