成员后的C＃自定义属性声明

Question

是否有人知道是否可以在成员之后而不是之前声明属性，因为它通常显示在引用/代码示例中？

示例：

public class MarkerAttribute: Attribute
{
    public MarkerAttribute(): base() { }
}

public class TheClass
{
    public int PropertyWithNoAttribute1 { get; set; }

    [Marker]
    public int PropertyWithAttribute { get; set; }

    public int PropertyWithNoAttribute2 { get; set; }
}

在这里，出于各种不感兴趣的原因，我想像这样代表同一个类（这相当于标准表示）：

public class TheClass
{
    public int PropertyWithNoAttribute1 { get; set; }

    [Marker] public int PropertyWithAttribute { get; set; } 

    public int PropertyWithNoAttribute2 { get; set; }
}

有没有人知道是否有一些特殊的语法指示，以便可以像这样编写同一个类？

public class TheClass
{
    public int PropertyWithNoAttribute1 { get; set; }

    public int PropertyWithAttribute { get; set; } [Marker]

    public int PropertyWithNoAttribute2 { get; set; }
}

我已经在以下计划中对此进行了测试，不幸的是它无法正常工作。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ScratchPad
{
    public class MarkerAttribute: Attribute
    {
        public MarkerAttribute(): base() { }
    }

    public class TheClass
    {
        public int PropertyWithNoAttribute1 { get; set; }

        public int PropertyWithAttribute { get; set; } [Marker]

        public int PropertyWithNoAttribute2 { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            TheClass a = new TheClass();

            System.Reflection.PropertyInfo PropertyWithNoAttribute1_Info =  a.GetType().GetProperty("PropertyWithNoAttribute1");
            System.Reflection.PropertyInfo PropertyWithAttribute_Info =     a.GetType().GetProperty("PropertyWithAttribute");
            System.Reflection.PropertyInfo PropertyWithNoAttribute2_Info =  a.GetType().GetProperty("PropertyWithNoAttribute2");

            object[] attributes = PropertyWithNoAttribute1_Info.GetCustomAttributes(typeof(MarkerAttribute), false);
            if (attributes.Length > 0)
            {
                System.Console.WriteLine("{0} has attribute {1}", PropertyWithNoAttribute1_Info.Name, attributes[0].GetType().Name);
            }

            attributes = PropertyWithAttribute_Info.GetCustomAttributes(typeof(MarkerAttribute), false);
            if (attributes.Length > 0)
            {
                System.Console.WriteLine("{0} has attribute {1}", PropertyWithAttribute_Info.Name, attributes[0].GetType().Name);
            }

            attributes = PropertyWithNoAttribute2_Info.GetCustomAttributes(typeof(MarkerAttribute), false);
            if (attributes.Length > 0)
            {
                System.Console.WriteLine("{0} has attribute {1}", PropertyWithNoAttribute2_Info.Name, attributes[0].GetType().Name);
            }
        }
    }
}

谢谢
