Automapper忽略嵌套属性

// 定义源对象
public class SourceObject
{
    public int Id { get; set; }
    public string Name { get; set; }
    public NestedObject Nested { get; set; }
}

// 定义嵌套对象
public class NestedObject
{
    public int NestedId { get; set; }
    public string NestedName { get; set; }
}

// 定义目标对象
public class DestinationObject
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string NestedName { get; set; }
}

// 创建映射配置
var config = new MapperConfiguration(cfg =>
{
    cfg.CreateMap<SourceObject, DestinationObject>()
        .ForMember(dest => dest.NestedName, opt => opt.Ignore());
});

// 执行映射
var mapper = config.CreateMapper();
var source = new SourceObject
{
    Id = 1,
    Name = "Source",
    Nested = new NestedObject
    {
        NestedId = 2,
        NestedName = "Nested"
    }
};
var destination = mapper.Map<SourceObject, DestinationObject>(source);

// 输出结果
Console.WriteLine(destination.Id); // 1
Console.WriteLine(destination.Name); // "Source"
Console.WriteLine(destination.NestedName); // null
