枚举描述，如果数据没有在枚举里面则会报错

[yccool]

public class Dto { public string Name { get; set; } public Type UserType { get; set; } }

public enum Type { [Description("General User")] V1, [Description("General Administrator")] V2, [Description("Super Administrator")] V3 }

当源数据，没有在枚举Type的Description里面的值时，会报错，导入导出都报错
