前端之家收集整理的这篇文章主要介绍了
对象和XML,JSON格式字符串的相互转换,
前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
- 对象和Json格式数据互转。这里用到了JSON.NET(Newtonsoft.json)需要应用外部dll,可自行下载
/// <summary>
/// 把对象序列化 JSON 字符串
/// </summary>
/// <typeparam name="T">对象类型</typeparam>
/// <param name="obj">对象实体</param>
/// <returns>JSON字符串</returns>
public static string ToJsonString<T>(this T obj)
{
var json = new DataContractJsonSerializer(typeof(T));
using (var ms = new MemoryStream())
{
json.WriteObject(ms,obj);
string szJson = Encoding.UTF8.GetString(ms.ToArray());
return szJson;
}
}
/// <summary>
/// 把JSON字符串还原为对象
/// </summary>
/// <typeparam name="T">对象类型</typeparam>
/// <param name="szJson">JSON字符串</param>
/// <returns>对象实体</returns>
public static T ParseFormJson<T>(this string szJson)
{
T obj = Activator.CreateInstance<T>();
using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(szJson)))
{
var dcj = new DataContractJsonSerializer(typeof(T));
return (T)dcj.ReadObject(ms);
}
}
- 对象和xml格式字符串互转。as作用:强制转换为引用类型,所以T要限制为class。
/// <summary>
/// 把对象转换为XML字符串
/// </summary>
/// <typeparam name="T">对象类型</typeparam>
/// <param name="obj">对象实体</param>
/// <returns>xml格式的字符串</returns>
public static string ToXmlString<T>(this T obj)
{
string xmlString;
var xmlSerializer = new XmlSerializer(typeof(T));
using (var ms = new MemoryStream())
{
var streamWriter = new StreamWriter(ms);
xmlSerializer.Serialize(streamWriter,obj);
xmlString = Encoding.UTF8.GetString(ms.ToArray());
}
return xmlString;
}
/// <summary>
/// 把XML格式的字符串还原为对象
/// </summary>
/// <typeparam name="T">对象类型</typeparam>
/// <param name="xml">xml格式字符串</param>
/// <returns>对象实体</returns>
public static T XmlToObject<T>(this string xml) where T : class
{
var xmlSerializer = new XmlSerializer(typeof(T));
using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
{
return xmlSerializer.Deserialize(ms) as T;
}
}
