推荐答案

您不需要将任何其他信息传递给Timer Tick事件处理程序：只需在表单中的类级别声明变量并正常访问它 - 它将像任何其他类字段一样工作。

You don't need to pass any additional information to the Timer Tick event handler: just declare the variable at class level within your form and access it normally - it will work exactly like any other class field.

这很简单。您无法在Time Tick事件中传递任何其他数据。您必须在事件之外跟踪此附加数据。但是，既然我们不知道你的代码是什么样的，那就不可能告诉你应该做什么了。

It's simple. You can't pass any additional data in the Time Tick event. You have to keep track of this additional data outside the event. But, since we have no idea what you're code looks like, it's impossible to tell you what you should be doing instead.
