c# - 从连接转换为对象

Question

我有一个返回三重对象列表的连接。我能以某种方式转换为这个对象的列表吗？

var result = entities.Join(...).Join(...).Join(.. new {a=a, b=b, c=c}).ToList();
//how to cast like:
var multipleList = (List<{ObjectA, ObjectB, ObjectC}>)result;

Answer 1

var multipleList = 
    result.SelectMany(x => new object[] { x.a, x.b, x.c })
          .ToList();
