DisplayAttribute应用——根据PropertyName自动获取对应的UI显示名
作者:互联网
model定义,使用DisplayAttribute
public class AddressSetInfo { /// <summary> /// invoiceAddress.Id /// </summary> [Display(Name = "Id")] public virtual Int64 Id { get; set; } }
enum定义,使用DisplayAttribute
public enum CustomerFinancialStatementCurrencyType { /// <summary> /// 人民币,CNY /// </summary> [Display(Name = "CNY")] RMB = 1, /// <summary> /// 美元 /// </summary> [Display(Name = "USD")] USD = 2 }
解析DisplayAttribute for class
/// <summary> /// GetPropertyNameDic /// </summary> /// <typeparam name="T">dictionary. key:PropertyName; value:PropertyDetail /// </typeparam> /// <returns></returns> public static Dictionary<string, PropertyDetail> GetPropertyNameDic<T>() { var result = new Dictionary<string, PropertyDetail>(); try { var typeOfObject = typeof(T); var pds = typeOfObject.GetProperties(); if (pds == null) { return result; } foreach (var p in pds) { var propertyItem = new PropertyDetail() { BelongToClassFullName=typeOfObject.FullName, PropertyName=p.Name }; var attr = p.GetCustomAttribute(typeof(DisplayAttribute)) as DisplayAttribute; if (attr != null) { propertyItem.DisplayName = attr.Name; } result.Add(p.Name, propertyItem); } } catch (Exception ex) { throw ex; } return result; }
解析DisplayAttribute for enum
/// <summary> /// GetEnumNameDicForDisplayAttr /// </summary> /// <param name="enumClassType">dictionary. key:enum Value; value:PropertyDetail</param> /// <returns></returns> public static Dictionary<string, PropertyDetail> GetEnumNameDicForDisplayAttr(Type enumClassType) { if (enumClassType == null) { throw new Exception("request is null"); } if(!enumClassType.IsEnum) { throw new Exception("request not enum type"); } var result = new Dictionary<string, PropertyDetail>(); try { var enumValues = enumClassType.GetEnumValues(); foreach (var value in enumValues) { MemberInfo memberInfo = enumClassType.GetMember(value.ToString()).First(); var valueItem = new PropertyDetail() { BelongToClassFullName = enumClassType.FullName, PropertyName = memberInfo.Name }; var descriptionAttribute = memberInfo.GetCustomAttribute<DisplayAttribute>(); if (descriptionAttribute != null) { valueItem.DisplayName = descriptionAttribute.Name; } result.Add(value.ToString(), valueItem); } } catch (Exception ex) { throw ex; } return result; } }
辅助model定义
/// <summary> /// PropertyDetail /// </summary> public class PropertyDetail { /// <summary> /// BelongToClassName /// </summary> public string BelongToClassFullName { get; set; } /// <summary> /// PropertyName /// </summary> public string PropertyName { get; set; } /// <summary> /// DisplayName /// </summary> public string DisplayName { get; set; } }
