写在这里,以备遗忘!!!
准备一个特性类
1 [AttributeUsage(AttributeTargets.Property, AllowMultiple = true)] 2 internal class NickNameAttribute : Attribute 3 { 4 public string NickName { get; set; } 5 6 public NickNameAttribute(string nickName) 7 { 8 this.NickName = nickName; 9 } 10 }
准备一个普通类 在属性上面加了特性
public class Test { [NickName("大写简称")] public string CName { get; set; } [NickName("简称")] [NickName("无意义简称")] public string Name { get; set; } [NickName("小写简称")] public string TName { get; set; } }
准备一个获取特性的方法类
1 public class NickNameAttributeHelper 2 { 3 /// <summary> 4 /// 获取特定特性的方法,可改写成泛型方法 5 /// </summary> 6 /// <param name="obj"></param> 7 /// <returns></returns> 8 public static List<string> GetPropertyAtrribute(object obj) 9 { 10 var list = new List<string>(); 11 12 var type = obj.GetType(); 13 var properties = type.GetProperties();//获取所有的属性 14 foreach (var property in properties) 15 { 16 if (property.IsDefined(typeof(NickNameAttribute), true))//判定属性是否定义了特定特性 17 { 18 var propertyName = property.Name + "-"; 19 var attributes = property.GetCustomAttributes(typeof(NickNameAttribute), true);//获取当前属性上面的指定特性 20 string value = default; 21 foreach (NickNameAttribute item in attributes) 22 { 23 value += item.NickName + "-"; 24 } 25 propertyName += value; 26 list.Add(propertyName); 27 } 28 } 29 30 return list; 31 } 32 }
运行
1 internal class Program 2 { 3 private static void Main(string[] args) 4 { 5 var test = new Test(); 6 7 var attributeValues = NickNameAttributeHelper.GetPropertyAtrribute(test); 8 9 attributeValues.ForEach(a => Console.WriteLine($"{a}")); 10 } 11 }
结果
