Mapster在映射隐藏属性时提供不明确的映射

Question

添加了一个小提琴手：https://dotnetfiddle.net/RgcDUF

{
public static void Main()
{
Console.WriteLine("Hello World");
TypeAdapterConfig<B, ADto>.NewConfig().Map(dest => dest.Id, src => src.Id);
var b = new B(){Id = 1};
var aDto = b.Adapt<ADto>();
Console.WriteLine(aDto.Id.ToString());
}
}
public class A{
public virtual long Id {get;set;}   
}
public class B : A{
public new int Id {get;set;}
}
public class ADto{
public int Id {get; set;}
}

因为我们将Id隐藏在B中，所以当将B映射到ADto时，Mapster会给出不明确的映射：

source=B
destination=ADto
type=Map

我知道这不是一个非常漂亮的代码，但在我清理代码之前，我需要这个代码。有没有一个设置可以让Mapster接受它应该只看Id，而不是偷看B.的引擎盖下面

Answer 1

找到了一个变通方法(不漂亮(

using Mapster;
public class Program
{
public static void Main()
{
Console.WriteLine("Hello World");
TypeAdapterConfig<B, ADto>.NewConfig()
.Map(dest => dest.Id, src => int.Parse(src.GetId()));
var b = new B(){Id = 1};
var aDto = b.Adapt<ADto>();
Console.WriteLine(aDto.Id.ToString());
}
}
public class A{
public virtual long Id {get;set;}   
}
public class B : A{
public new int Id {get;set;}
public int GetId(){
return Id;
}
}
public class ADto{
public int Id {get; set;}
}

从本质上讲，对src属性调用.ToString((似乎可以让mapster看起来不那么隐蔽，而且它很有效。

编辑：更改以反映Luke Briggs的建议，即使用方法返回Id而不是ToString((，这确实有效，而且很可能更快、更安全。
