Automapper公约 [英] Automapper Convention

问题描述

时，可以使用 Automapper 设置一个惯例，这样的地图不必被手的情况下创建，其中实体您。被映射到刚刚已经说视图模型追加

Is is possible with Automapper to setup a convention so that maps do not have to be created by hand for situations where the entity you are mapping to just has say "ViewModel" appended.

作为一个例子，我宁可不要设置如下图：

As an example I would rather not have to setup the following map:

Mapper.CreateMap<Error, ErrorViewModel>();

我明白，如果投影需要，我需要创建一个自定义的地图，但有一个约定， 。创建地图将是很好的。

I understand if projection is required that I would need to create a custom map, but having a convention to create maps would be nice.

推荐答案

您需要使用 Mapper.DynamicMap< TDest>（源）映射。

正如你可以在下面的例子中看到，它会自动从源匹配属性映射到目的地。

As you can see in the example below, it automatically maps the matching properties from source to destination.

using AutoMapper;
using System.Diagnostics;

class Program
{
    static void Main(string[] args)
    {
        var source = new Foo {Value = "Abc"};
        var destination = Mapper.DynamicMap<FooViewModel>(source);

        Debug.Assert(source.Value == destination.Value);
    }
}

public class Foo
{
    public string Value { get; set; }
}

public class FooViewModel
{
    public string Value { get; set; }
}
