The static Current property uses the Stack.Peek method to return the T instance at the top of the stack if one exists, returning null if the Stack is empty.
静态 Current 属性使用 Stack.Peek 方法返回位于堆栈顶端的 T 实例(如果存在),如果 Stack 为空则返回空。
Perhaps the solution here is to retroactively create base classes for IList that separate the methods that accept a T value from the ones that return one.
或许这里应该针对IList创建一个基类,该类会将接受T与返回T的方法区分开来。
Now return to your test page and find the t: column tag that you added in the earlier steps.
现在返回测试页面,并找到您在前面步骤中添加的t: column标签。
