假如我想得到c里面的id这个的值 如何做？
如何用Newtonsoft.Json来解析？？

[wuyq11]

string jsonText = "";
JsonReader reader = new JsonReader(new StringReader(jsonText));
while (reader.Read())
{
Console.WriteLine(WriteValue(reader.ValueType) + "\t\t" + WriteValue(reader.Value))
}
定义实体类
public class A
{

}

string jsonText = @""；
List <A> lst= new List <A>();
lst=JavaScriptConvert.DeserializeObject <List <A>>(jsonText );
foreach(A a in lst)
{
}
