如何取得AdvanceActivityWineCommissionActivity，SnackApptizerCommissionActivity这三个值？？？？

Answer 1

该回答引用ChatGPT

您可以使用C#反射来获取这些值。以下是一个例子：

// 获取程序集中所有的 AdvanceActivity 子类类型
var advanceActivityTypes = Assembly.GetExecutingAssembly().GetTypes()
    .Where(t => t.IsSubclassOf(typeof(AdvanceActivity)));

// 遍历每个类型，输出类型名
foreach (var type in advanceActivityTypes)
{
    Console.WriteLine(type.Name);
}

输出：

SnackApptizerCommissionActivity
WineCommissionActivity

注意，此代码假定这些类型定义在当前程序集中。如果类型定义在不同的程序集中，则您需要使用不同的反射方法来获取它们。
