C#读取匿名对象

通过new出匿名对象，可以直接调用该匿名对象的属性名，获取属性值。

var objUser = new {Name="Lilei",Age=18 };
//此时可直接读取匿名类属性
Console.WriteLine("Name:" + objUser.Name);// Name:Lilei

但当将匿名对象转换成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;
}
static void Main(string[] args)
{
    var obj = GetObj();//此时已无法通过obj.Name的方式获取属性值了
}

1、通过反射的方式获取属性值

static object GetObj()
{
    var obj = new { Name = "Lilei", Age = 18 };
    return obj;
}
static void Main(string[] args)
{
    var obj = GetObj();
    //此时可通过反射的方式获取属性值
    string objName = obj.GetType().GetProperty("Name").GetValue(obj).ToString();
    Console.WriteLine(objName);// Lilei
}

 var Data = this.GetWorkHours(QueryDto);
 var Result = Data.GetType().GetProperty("Result").GetValue(Data); // 反射获取获取 Result
 var dtoList = Result.GetType().GetProperty("dtoList").GetValue(Result); //再通过Result获取dtoList

2、新建个扩展方法，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;
    }
}
