要解决这个问题，我们可以使用Automapper内置的Ignore方法来忽略List类型的属性，然后分别映射其他属性。下面是一个示例代码：

//定义源和目标类 public class Source { public string Name { get; set; } public int Age { get; set; } public List Hobbies { get; set; } }

public class Destination { public string Name { get; set; } public int Age { get; set; } public List Hobbies { get; set; } }

//创建AutoMapper配置文件 var config = new MapperConfiguration(cfg => { cfg.CreateMap() .ForMember(dest => dest.Hobbies, opt => opt.Ignore()) // 忽略Hobbies属性 .ForMember(dest => dest.Name, opt => opt.MapFrom(src => src.Name)) .ForMember(dest => dest.Age, opt => opt.MapFrom(src => src.Age));

});

//执行映射 var source = new Source { Name = "John", Age = 30, Hobbies = new List { "Reading", "Swimming" } }; var dest = new Destination { Name = "Tom", Age = 28, Hobbies = new List { "Hiking" } }; dest = config.CreateMapper().Map(source, dest);

//输出 Console.WriteLine(dest.Name); // John Console.WriteLine(dest.Age); // 30 Console.WriteLine(dest.Hobbies); // ["Reading", "Swimming"]

在这个示例中，我们使用了Ignore方法来忽略了List类型的属性Hobbies，然后分别映射其他的属性。这样操作后，不管源类中的Hobbies属性怎么变化，这个属性都不会映射到目标类中。
