JSON格式转换

代码1：

引用：System.ServiceModel.Web程序集（系统内置）

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

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

代码2：
引用：System.Text.RegularExpressions; System.Runtime.Serialization.Json;

public static string ObjectToJson<T>(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<T>(string json)
{
string p = @"\d{4}-\d{2}-\d{2}\s\d{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();
return (T)json1.ConvertStringToValue(json, typeof(T));
T data = (T)serializer.ReadObject(ms);
return data;
}
}
