如何将.net属性应用于返回类型

using System;

public class ExampleAttribute : Attribute
{
    public string Description { get; set; }

    public ExampleAttribute(string description)
    {
        Description = description;
    }
}

public class MyClass
{
    [Example("This is a sample description")]
    public string MyMethod()
    {
        return "Hello, World!";
    }
}

public class Program
{
    public static void Main()
    {
        var myClass = new MyClass();
        var result = myClass.MyMethod();
        Console.WriteLine(result);
    }
}
