我难以从枚举描述属性进行映射。我一直在寻找一个有用的例子,运气很少。我知道还有其他一些例子,但我仍然在努力应对这种特殊情况。
这是我的枚举:
public enum ResolveCodeEnum
{
[Description("Resolved - Workaround")]
ResolvedWorkaround = 1,
[Description("Resolved - Permanently")]
ResolvedPermanently = 2,
[Description("Resolved - Unknown")]
ResolvedUnkown = 3,
[Description("Cannot Reproduce")]
CannotReproduce = 4,
[Description("Invalid")]
Invalid = 5,
[Description("Cancelled")]
Cancelled = 6
}
这是我的Enum Helper课程:
public class EnumHelper
{
public static string GetEnumDescription(Enum value)
{
FieldInfo fi = value.GetType().GetField(value.ToString());
DescriptionAttribute[] attributes =
(DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);
if (attributes != null && attributes.Length > 0)
return attributes[0].Description;
else
return value.ToString();
}
}
我的目标是通过枚举说明属性
将源映射到目标以下是我目前在映射配置中所拥有的内容:
Mapper.CreateMap<Result, Incident>()
.ForMember(dest => dest.Status,
opts => opts.MapFrom(src => src.state));
这是缩写的Result类:
public class Result
{
public string sys_id { get; set; }
public string state { get; set; }
}
这是简短的Incident类:
public class Incident
{
public string Id{ get; set; }
public string Status{ get; set; }
}
注意:Result类的state属性是一个字符串
例如:
我的目标是获得
Incident.Status = "Resolved - Workaround"
来自
Result.state = "1"
我一直在努力使用自动播放器语法来与我的EnumHelper类一起使用
如果有人可以帮我解决这个问题,我们将不胜感激:)
答案 0 :(得分:2)
两种方法:
与stdio: [0, 'pipe', 'pipe']
内联:
ResolveUsing
使用自定义 Mapper.CreateMap<Result, Incident>()
.ForMember(
dest => dest.Status,
opt => opt.ResolveUsing(src =>
{
var value = (ResolveCodeEnum)Enum.Parse(
typeof(ResolveCodeEnum), src.state);
return EnumHelper.GetEnumDescription(value);
}));
:
ValueResolver
用法:
public class EnumValueResolver : ValueResolver<Result, string>
{
protected override string ResolveCore(Result src)
{
var value = (ResolveCodeEnum)Enum.Parse(typeof(ResolveCodeEnum), src.state);
return EnumHelper.GetEnumDescription(value);
}
}
我推荐#2,因为它更干净。
