新旧变量 [英] old and new variables

问题描述

Hello Everyone，

如果我总是发生一件事，

Hello Everyone,
If i have an event that happens always,

Application.Idle += Myevent;

如果在此活动中每次都有变化，

and if there is a variable that changes every time in this event,

Myevent()
{
   var = value;
}

如何捕获此变量的旧值和新值，然后比较，



在此先感谢，

How can i capture old value and new value of this variable and then compare between,

Thanks in advance,
z3ngew

推荐答案

试试这个：

Hi,

Try this:

int oldVar = aVar; // I use int in this example
                   // I also use aVar instead of var, because var is a keyword
int newVar = value;
// compare

aVariable = newVar;

希望这会有所帮助。

Hope this helps.
