我有一个匿名课程:

var someAnonymousClass = new
{
    SomeInt = 25,
    SomeString = "Hello anonymous Classes!",
    SomeDate = DateTime.Now
};

无论如何将属性附加到此类？反思,其他？我真的希望这样的事情:

var someAnonymousClass = new
{
    [MyAttribute()]
    SomeInt = 25,
    SomeString = "Hello anonymous Classes!",
    SomeDate = DateTime.Now
};

如何将MarshalAsAttribute应用于下面代码的返回类型？

public ISomething Foo()
{
    return new MyFoo();
}
