基于自定义属性筛选的C# return [Description]属性

using System;
using System.ComponentModel;

public class MyClass
{
    [Description("This is a sample method.")]
    public void SampleMethod()
    {
        // Method implementation
    }
    
    [Description("This is another method.")]
    public void AnotherMethod()
    {
        // Method implementation
    }
}

public class Program
{
    public static void Main()
    {
        var myClass = new MyClass();
        
        // 获取MyClass中标记有[Description]特性的方法
        var methods = myClass.GetType().GetMethods();
        
        foreach (var method in methods)
        {
            var attribute = Attribute.GetCustomAttribute(method, typeof(DescriptionAttribute)) as DescriptionAttribute;
            
            if (attribute != null && attribute.Description == "This is a sample method.")
            {
                // 执行特定的逻辑
                Console.WriteLine("Found a method with the specified description!");
                method.Invoke(myClass, null);
            }
        }
    }
}
