C# 编写通用的JSON数据进行序列化和反序列化
注意事项:使用JSON系列化和反系列化,必须要添加引用System.Runtime.Serialization。
1.通用类代码如下:
/// <summary>
/// JSON序列化和反序列化辅助类
/// </summary>
public class JsonHelper
{
/// <summary>
/// JSON序列化
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="t"></param>
/// <returns></returns>
public static string JsonSerializer<T>(T t)
{
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
MemoryStream ms = new MemoryStream();
ser.WriteObject(ms, t);
string jsonString = Encoding.UTF8.GetString(ms.ToArray());
ms.Close();
return jsonString;
}
/// <summary>
/// JSON反序列化
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="jsonString"></param>
/// <returns></returns>
public static T JsonDeserialize<T>(string jsonString)
{
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
T obj = (T)ser.ReadObject(ms);
ms.Close();
return obj;
}
}
2.定义调用类,如下:
/// <summary>
/// 定义类
/// </summary>
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
}
3.调用系列化和反系列化的操作如下:
Person p = new Person();
p.Name = "陈磊";
p.Age = 29;
//调用JSON系列化
string strJson = JsonHelper.JsonSerializer<Person>(p);
Console.WriteLine(strJson);
//调用JSON反系列化
string strDJson = "{\"Age\":28,\"Name\":\"陈磊\"}";
Person dp = JsonHelper.JsonDeserialize<Person>(strDJson);
Console.WriteLine(dp.Name + "," + dp.Age);
