推荐答案

代码看起来正确 - 所以要做的第一件事就是遵循代码并查看实际发生的情况。

在事件处理程序的第一行放置一个断点，然后单步执行通过，随时查看变量。



很抱歉，但是有了这些小信息，那就是我现在能给出的最好的建议。请记住，我无法访问您的代码，因此无法在原地运行以检查...

The code looks right - so the first thing to do is to follow the code and see what is actually happening.
Put a breakpoint on the first line in the event handler, and single step through, looking at the variables as you go.

Sorry, but with that little info, that's about the best advice I can give at the moment. And remember, I don't have access to your code so I can't run it in situ to check...
