Automapper仅忽略一个集合属性

// 定义源对象和目标对象
public class SourceObject
{
    public List<string> CollectionProperty { get; set; }
    // 其他属性...
}

public class DestinationObject
{
    public List<string> CollectionProperty { get; set; }
    // 其他属性...
}

// 配置Automapper映射规则
var config = new MapperConfiguration(cfg =>
{
    cfg.CreateMap<SourceObject, DestinationObject>()
        .ForMember(dest => dest.CollectionProperty, opt => opt.Ignore());
});

// 创建映射器
var mapper = config.CreateMapper();

// 执行映射
var source = new SourceObject { CollectionProperty = new List<string> { "item1", "item2" } };
var destination = mapper.Map<SourceObject, DestinationObject>(source);

// 输出结果
Console.WriteLine(destination.CollectionProperty); // null
