C#遍历类的属性 PropertyInfo.Attributes（转）

PropertyInfo.Attributes 属性

此属性表示与成员关联的特性。 所有成员都具有相对于特定成员类型定义的特性集。 属性特性使用户能够知道此属性是否是默认属性、SpecialName 属性等等。

若要获取 Attributes 属性，请先获取类类型。 从 Type 获取 PropertyInfo。 从 PropertyInfo 获取特性。

官方示例：获取类的特性

using System;
using System.Reflection;

public class Myproperty
{
    private string caption = "Default caption";
    public string Caption
    {
        get{return caption;}
        set {if(caption!=value) {caption = value;}
        }
    }
}

class Mypropertyinfo
{
    public static int Main(string[] args)
    {
        Console.WriteLine("\nReflection.PropertyInfo");

        // Define a property.
        Myproperty Myproperty = new Myproperty();
        Console.Write("\nMyproperty.Caption = " + Myproperty.Caption);

        // Get the type and PropertyInfo.
        Type MyType = Type.GetType("Myproperty");
        PropertyInfo Mypropertyinfo = MyType.GetProperty("Caption");

        // Get and display the attributes property.
        PropertyAttributes Myattributes = Mypropertyinfo.Attributes;

        Console.Write("\nPropertyAttributes - " + Myattributes.ToString());

        return 0;
    }
}

一个例子： 注意：貌似对字段无效

先建一个类User

namespace ClassLibrary1
{
    public class User    
    {       
        private int userid = 1;
        public int Userid
        { 
            get { return userid; }
            set { userid = value; }
        }  
        private string userName = "jghg";       
        public string UserName{
            get { return userName; } 
            set { userName = value; }
        }
        private string address = "ghjghj";
        public string Address{ 
            get { return address; } 
            set { address = value; }
        }        
        private string email = "jhgjhg";
        public string Email{
            get { return email; }
            set { email = value; }
        }
        private string phone = "ghjgjg";
        public string Phone
        { 
            get { return phone; }
            set { phone = value; }
        }
    }
}

接着在主程序中获取类的属性，看代码

namespace ConsoleApplication2 { 
    class Program { 
        static void Main(string[] args) 
        { 
            Type type = typeof(ClassLibrary1.User); 
            object obj = Activator.CreateInstance(type); 
            PropertyInfo[] props = type.GetProperties(BindingFlags.Public | BindingFlags.Instance); 
            foreach (PropertyInfo p in props) { 
                Console.WriteLine(p.Name); 
            } 
            Console.ReadLine(); 
        }
    } 
}

需要引入命名空间：

using System.Reflection;
