C# .NET内核如何获取自定义属性的值？

using System;

// 自定义属性
[AttributeUsage(AttributeTargets.Class)]
public class CustomAttribute : Attribute
{
    public string Value { get; set; }

    public CustomAttribute(string value)
    {
        Value = value;
    }
}

// 目标类型
[Custom("Custom Value")]
public class MyClass
{
    // ...
}

class Program
{
    static void Main(string[] args)
    {
        Type type = typeof(MyClass);
        object[] attributes = type.GetCustomAttributes(true);

        foreach (object attribute in attributes)
        {
            if (attribute is CustomAttribute customAttribute)
            {
                Console.WriteLine(customAttribute.Value);
            }
        }
    }
}
