屬性描述

定義為PropertyInfo的擴展方法

/// <summary> /// 獲取屬性描述 /// </summary> /// <param name="t"></param> /// <returns></returns> public static string GetDesc(this PropertyInfo t) {string des = ((DescriptionAttribute)Attribute.GetCustomAttribute(t, typeof(DescriptionAttribute)))?.Description ?? null;// 屬性描述return des; }

屬性相關操作

是否擁有某屬性，獲取某屬性值，設置某屬性值，是否擁有某字段，獲取某字段值，設置某字段值，獲取實體層描述

private static BindingFlags _bindingFlags { get; }= BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Public | BindingFlags.Static; /// <summary> /// 是否擁有某屬性 /// </summary> /// <param name="obj"> 對象 </param> /// <param name="propertyName"> 屬性名 </param> /// <returns> </returns> public static bool ContainsProperty(this object obj, string propertyName) {return obj.GetType().GetProperty(propertyName, _bindingFlags) != null; }/// <summary> /// 獲取某屬性值 /// </summary> /// <param name="obj"> 對象 </param> /// <param name="propertyName"> 屬性名 </param> /// <returns> </returns> public static object GetPropertyValue(this object obj, string propertyName) {return obj.GetType().GetProperty(propertyName, _bindingFlags).GetValue(obj); }/// <summary> /// 設置某屬性值 /// </summary> /// <param name="obj"> 對象 </param> /// <param name="propertyName"> 屬性名 </param> /// <param name="value"> 值 </param> /// <returns> </returns> public static void SetPropertyValue(this object obj, string propertyName, object value) {obj.GetType().GetProperty(propertyName, _bindingFlags).SetValue(obj, value); }/// <summary> /// 是否擁有某字段 /// </summary> /// <param name="obj"> 對象 </param> /// <param name="fieldName"> 字段名 </param> /// <returns> </returns> public static bool ContainsField(this object obj, string fieldName) {return obj.GetType().GetField(fieldName, _bindingFlags) != null; }/// <summary> /// 獲取某字段值 /// </summary> /// <param name="obj"> 對象 </param> /// <param name="fieldName"> 字段名 </param> /// <returns> </returns> public static object GetGetFieldValue(this object obj, string fieldName) {return obj.GetType().GetField(fieldName, _bindingFlags).GetValue(obj); }/// <summary> /// 設置某字段值 /// </summary> /// <param name="obj"> 對象 </param> /// <param name="fieldName"> 字段名 </param> /// <param name="value"> 值 </param> /// <returns> </returns> public static void SetFieldValue(this object obj, string fieldName, object value) {obj.GetType().GetField(fieldName, _bindingFlags).SetValue(obj, value); }/// <summary> /// 獲取某字段值 /// </summary> /// <param name="obj"> 對象 </param> /// <param name="methodName"> 方法名 </param> /// <returns> </returns> public static MethodInfo GetMethod(this object obj, string methodName) {return obj.GetType().GetMethod(methodName, _bindingFlags); } /// <summary> /// 獲取實體層描述 /// </summary> /// <param name="value"> </param> /// <param name="Name"> </param> /// <returns> </returns> public static string GetEntityDescription(this Type value, string Name) {PropertyDescriptor s = TypeDescriptor.GetProperties(value)[Name];DescriptionAttribute description = s == null ? null : s.Attributes[typeof(DescriptionAttribute)] as DescriptionAttribute;return description == null ? "" : description.Description; }/// <summary> /// 獲取實體層描述 /// </summary> /// <param name="s"> </param> /// <returns> </returns> public static string GetEntityDescription(this PropertyDescriptor s) {DescriptionAttribute description = s == null ? null : s.Attributes[typeof(DescriptionAttribute)] as DescriptionAttribute;return description == null ? "" : description.Description; }

枚舉描述

定義為擴展方法

/// <summary>/// 獲取枚舉描述/// </summary>/// <param name="value"> 枚舉值 </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>/// 知道枚舉,傳入枚舉英文,獲取描述/// </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;}
