如何解析json?
请告诉我在asp.net c#中反序列化json数据的方法。事实上,我有一个json数据,其中有两个对象,比如:
{
"errstr": "All downloded vedios ",
"errcode": 0,
"result": {
"videos": [
{
"id": "22",
"name": "Ashley",
"price": "0.49",
"size": "3712310"
}
],
"trailer": [
{
"id": "1",
"trailer_name": "charl1",
"status": "1"
},
{
"id": "2",
"trailer_name": "charl2",
"status": "1"
}
]
}
}
这里我有两个对象视频和预告片。请告诉我在代码中获取这些数据的过程。
您需要创建一个具有嵌套成员的类例如json文件
{
"GeminiURL":"https://gemini.com/Gemini"
,"Language":"en"
,"Log":{"Debug":true,"Info":true,"Warn":true,"FileName":"d:''temp''tfsgemini.log"}
}
使用c#类进行序列化和反序列化
public class Settings
{
public string GeminiURL;
private LogSettings _log;
public LogSettings Log
{
get { return _log = _log ?? new LogSettings(); }
set { _log = value; }
}
public string Language;
public Settings()
{
// defaule settings can be assigned here;
}
}
public class LogSettings
{
public bool Debug;
public bool Info = true;
public bool Warn = true;
public string FileName;
}
反序列化代码看起来像:
public static T Load(string fileName)
{
T t = new T();
if (File.Exists(fileName))
t = (new JavaScriptSerializer()).Deserialize<T>(File.ReadAllText(fileName));
else
Save(t);
return t;
}
