PropertyInfo.Attributes 屬性
此屬性工作表示與成員關聯的特性。 所有成員都具有相對於特定成員類型定義的特性集。 屬性特性使使用者能夠知道此屬性是否是預設屬性、SpecialName 屬性等等。
若要擷取 Attributes 屬性,請先擷取類類型。 從 Type 擷取 PropertyInfo。 從 PropertyInfo 擷取特性。
官方樣本:擷取類的特性
1 using System; 2 using System.Reflection; 3 4 public class Myproperty 5 { 6 private string caption = "Default caption"; 7 public string Caption 8 { 9 get{return caption;}10 set {if(caption!=value) {caption = value;}11 }12 }13 }14 15 class Mypropertyinfo16 {17 public static int Main(string[] args)18 {19 Console.WriteLine("\nReflection.PropertyInfo");20 21 // Define a property.22 Myproperty Myproperty = new Myproperty();23 Console.Write("\nMyproperty.Caption = " + Myproperty.Caption);24 25 // Get the type and PropertyInfo.26 Type MyType = Type.GetType("Myproperty");27 PropertyInfo Mypropertyinfo = MyType.GetProperty("Caption");28 29 // Get and display the attributes property.30 PropertyAttributes Myattributes = Mypropertyinfo.Attributes;31 32 Console.Write("\nPropertyAttributes - " + Myattributes.ToString());33 34 return 0;35 }36 }

一個例子: 注意:貌似對欄位無效
先建一個類User
1 namespace ClassLibrary1 2 { 3 public class User 4 { 5 private int userid = 1; 6 public int Userid 7 { 8 get { return userid; } 9 set { userid = value; }10 } 11 private string userName = "jghg"; 12 public string UserName{13 get { return userName; } 14 set { userName = value; }15 }16 private string address = "ghjghj";17 public string Address{ 18 get { return address; } 19 set { address = value; }20 } 21 private string email = "jhgjhg";22 public string Email{23 get { return email; }24 set { email = value; }25 }26 private string phone = "ghjgjg";27 public string Phone28 { 29 get { return phone; }30 set { phone = value; }31 }32 }33 }
接著在主程式中擷取類的屬性,看代碼
1 namespace ConsoleApplication2 { 2 class Program { 3 static void Main(string[] args) 4 { 5 Type type = typeof(ClassLibrary1.User); 6 object obj = Activator.CreateInstance(type); 7 PropertyInfo[] props = type.GetProperties(BindingFlags.Public | BindingFlags.Instance); 8 foreach (PropertyInfo p in props) { 9 Console.WriteLine(p.Name); 10 } 11 Console.ReadLine(); 12 }13 } 14 }
需要引入命名空間:
using System.Reflection;
