c# – 有关As <>()方法在AutoMapper中的作用的详细信息

我已经做了相当多的谷歌搜索,我查看了AutoMapper维基,我找不到As<>的定义方法在AutoMapper中.

我有一些猜测.我玩了一下.但我觉得我需要看一些文档.

我认为该方法的名称对于有效的谷歌搜索来说太普通了.

如果有人知道这个方法的文档在哪里(或知道它的进出),请发布它.

解决方法

它是映射重定向.以下测试证明了这一点：

[TestFixture]
public class DestinationTypepolymorphismTest
{
    public class Customer
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }

    public class CustomerStubDTO
    {
        public int Id { get; set; }
    }

    public class CustomerDTO : CustomerStubDTO
    {
        public string Name { get; set; }
    }

    public class Order
    {
        public Customer Customer { get; set; }
    }

    public class OrderDTO
    {
        public CustomerStubDTO Customer { get; set; }
    }


    [Test]
    public void Mapper_Should_Allow_Overriding_Of_Destination_Type()
    {
        var order = new Order() { Customer = new Customer() { Id = 1,Name = "A" } };
        Mapper.CreateMap<Order,OrderDTO>();
        Mapper.CreateMap<Customer,CustomerDTO>();
        Mapper.CreateMap<Customer,CustomerStubDTO>().As<CustomerDTO>();
        var orderDto = Mapper.Map<Order,OrderDTO>(order);

        var customerDto = (CustomerDTO)orderDto.Customer;
        Assert.AreEqual("A",customerDto.Name);
        Assert.AreEqual(1,customerDto.Id);

    }

}
