推荐答案

C#没有全局变量.您可能是说一个类成员变量吗?

在重置"按钮中，您声明(并初始化)变量的新实例，从而遮盖(可能的)类成员变量.

您必须从以下位置更改(在重置"按钮命令处理程序中):

C# has no global variables. Possibly do you mean a class member variable?

In the reset button you are declaring (and initializing) a new instance of the variable and thus shadowing the (possible) class member variable.

You have to change (in the reset button command handler) from:

int i = 0;

到

to

i = 0;

仅在重置按钮上写入

write on reset button only

i=0;
