直接获取匿名对象属性

创建匿名对象：

var objUser = new {Name="Lilei",Age=18 };

一般在一个代码块中，可以直接获取匿名对象属性

Console.WriteLine("Name:" + objUser.Name);

提出问题

当匿名对象转换成 object 后，就 无法 直接读取属性值了

static object GetObj()
{
    var obj = new { Name = "Lilei", Age = 18 };
    return obj;
}

通过扩展方法，将object转成对应的匿名对象

class Program
{
    static void Main(string[] args)
    {
        var obj = GetObj();
        var user = obj.ObjCast(new { Name = "", Age = 0 });
        Console.WriteLine("Name:{0},Age:{1}", user.Name, user.Age);// Name:Lilei,Age:18

          var objList = GetObjList();
          var userList = objList.Select(p => p.ObjCast(new { Name = "", Age = 0 })).ToList();
          userList.ForEach(p =>
          {
            Console.WriteLine("Name:{0},Age:{1}", p.Name, p.Age);
          });
          // Name:Lilei,Age:18
          // Name:HanMeimei,Age:20
    }
    static object GetObj()
    {
        var obj = new { Name = "Lilei", Age = 18 };
        return obj;
    }
    static List<object> GetObjList()
    {
        List<object> objList = new List<object>();
        objList.Add(new { Name = "Lilei", Age = 18 });
        objList.Add(new { Name = "HanMeimei", Age = 20 });
        return objList;
    }
}
static class Extensions
{
    public static T ObjCast<T>(this object obj, T sample)
    {
        return (T)obj;
    }
}
