推荐答案

如果您不想使用此事件.然后只需删除事件处理程序即可.

If you do not want to use this event. then just remove the event handler.

有时，您可以通过在输入代码时设置一个布尔值来解决此问题.但是，首先您要检查该布尔值是否正确.如果是，请跳过代码.一旦传递了if语句，请将变量设置为true.在退出代码之前，请清除bool.

Sometimes you can deal with this problem by having a bool that you set when you enter the code. However, first you check if this bool is true. If it is, skip the code. Once pass the if statement, set the variable to true. Before you exit the code, clear the bool.
