C# -- 把json字符串转为对象并读取各属性的值

前面2种方法是不需要声明一个Json字符串的类型即可把Json字符串转换为Dictionary对象

而第3种方法则是声明一个Json字符串的强类型对象，然后反序列化为该对象的数据。

 

   List< 
  string> list =  
  new List< 
  string>(); 
  
             
  string json = JsonConvert.SerializeObject( 
  new { Name =  
  " 
  jeff 
  ", Age =  
  23, Code =  
  " 
  f04536a3-832c-4ebd-95d0-15af82dbb1a2 
  ", PhoneNumber =  
  " 
  15902104019 
  " }); 
  
            IDictionary< 
  string, JToken> data = JsonConvert.DeserializeObject<JObject>(json); 
  
             
  foreach ( 
  var i  
  in data) 
  
            { 
  
                 
  string key = i.Key; 
  
                 
  var value = i.Value; 
  
                 
  if (value.Type.ToString() ==  
  " 
  String 
  ") 
  
                { 
  
                    list.Add(value.ToString()); 
  
                } 
  
            } 
  
 
  
 
  
             
  var result = JsonConvert.DeserializeObject<IDictionary< 
  string,  
  object>>(json); 
  
             
  var name = result[ 
  " 
  Name 
  "]; 
  
             
  var age = result[ 
  " 
  Age 
  "]; 
  
 
  
             
  foreach ( 
  var p  
  in result.Keys) 
  
            { 
  
                 
  var value = result[p]; 
  
            } 
  
 
  
             
  int j =  
  0; 
  
             
  foreach ( 
  var p  
  in result) 
  
            { 
  
                 
  var key = p.Key; 
  
                 
  var value = p.Value; 
  
                 
  var type = p.Value.GetType(); 
  
                 
  if (type ==  
  typeof( 
  string)) 
  
                { 
  
                    j +=  
  1; 
  
                } 
  
            } 
  
 
  
            clsTest obj = JsonConvert.DeserializeObject<clsTest>(json); 
  
             
  var name1 = obj.GetType().GetProperty( 
  " 
  Name 
  "); 
  
             
  foreach ( 
  var p  
  in obj.GetType().GetProperties()) 
  
            { 
  
                 
  var type = p.GetType().Name; 
  
                 
  var key = p.Name; 
  
                 
  var value = p.GetValue(obj); 
  
            }
