使用DataContractJsonSerializer进行JSON序列化的JSONHelper类

public static class JSONHelper
{
/// 

/// 将对象转化为Json字符串
/// 
/// 对象类型
/// 对象本身
/// JSON字符串
public static string Serializer(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;
}
}
/// 

/// 将字符串转化为JSON对象，如果转换失败，返回default(T)
/// 
/// 对象类型
/// 字符串
/// 转换值
public static T Deserializer(this string s)
{
try
{
DataContractJsonSerializer js = new DataContractJsonSerializer(typeof(T));
using (MemoryStream ms = new MemoryStream())
{
StreamWriter sw = new StreamWriter(ms);
sw.Write(s);
sw.Flush();
ms.Seek(0, SeekOrigin.Begin);
return (T)js.ReadObject(ms);
}
}
catch
{
return default(T);
}
}
}
