属性描述
定义为PropertyInfo的扩展方法
/// <summary>/// 获取属性描述/// </summary>/// <param name="t"></param>/// <returns></returns>public static string GetDesc(this PropertyInfo t){string des = ((DescriptionAttribute)Attribute.GetCustomAttribute(t, typeof(DescriptionAttribute)))?.Description ?? null;// 属性描述return des;}
属性相关操作
是否拥有某属性，获取某属性值，设置某属性值，是否拥有某字段，获取某字段值，设置某字段值，获取实体层描述

枚举描述
定义为扩展方法
/// <summary>/// 获取枚举描述/// </summary>/// <param name="value"> 枚举值 </param>/// <returns> </returns>public static string GetDescription(this Enum value){DescriptionAttribute attribute = value.GetType().GetField(value.ToString()).GetCustomAttributes(typeof(DescriptionAttribute), false).SingleOrDefault() as DescriptionAttribute;return attribute == null ? value.ToString() : attribute.Description;}/// <summary>/// 知道枚举,传入枚举英文,获取描述/// </summary>/// <param name="value"> </param>/// <param name="Name"> </param>/// <returns> </returns>public static string GetDescription(this Type value, string Name){DescriptionAttribute attribute = value.GetField(Name).GetCustomAttributes(typeof(DescriptionAttribute), false).SingleOrDefault() as DescriptionAttribute;return attribute == null ? value.ToString() : attribute.Description;}
C# .NET Core获取类属性/属性值 是否有属性/属性值 获取实体层描述 枚举描述 枚举英文获取枚举描述[Description(“xxx“)]
