使用DataContractJsonSerializer进行JSON序列化的JSONHelper类

public static class JSONHelper

/// <summary>
/// 将对象转化为Json字符串
/// </summary>
/// <typeparam name="T">对象类型</typeparam>
/// <param name="instanse">对象本身</param>
/// <returns>JSON字符串</returns>
public static string Serializer<T>(this T instanse)
{
try
{
DataContractJsonSerializer js = new DataContractJsonSerializer(typeof(T));
using (MemoryStream ms = new MemoryStream())
{
js.WriteObject(ms,instanse);
ms.Flush();
ms.Seek(0,SeekOrigin.Begin);
StreamReader sr = new StreamReader(ms);
return sr.ReadToEnd();
}
}
catch
{
return String.Empty;
}
}
/// <summary>
/// 将字符串转化为JSON对象，如果转换失败，返回default(T)
/// </summary>
/// <typeparam name="T">对象类型</typeparam>
/// <param name="s">字符串</param>
/// <returns>转换值</returns>
public static T Deserializer<T>(this string s)
{
try
