Question

我正在使用计时器和数组创建基于Windows窗体的多点击（旧手机键盘）类型系统。但是，每当我单击一个按钮将文本附加到文本框时，菜单条会垂直复制，我不知道为什么看起来像我已经注意到我的CS中的菜单字符串。代码本身没有完成，我只是想阻止这种重复发生，并且数组中的字符实际上附加到Rich Text Box。任何帮助都将不胜感激，谢谢！

                appendChar(ref keyPad2);
            }

            public void appendChar(ref string[] key)
            {
                runTimer();
                if (currentIndex == -1)
                {
                    currentIndex++;
                    rtbCurrentString.AppendText(key[currentIndex]);
                }
            }
        }
    }

这是我之前制作过的形式的重新编码有同样的错误，我决定从头开始修复它，但事实并非如此。

更新：关闭模式按钮不再有效，在发生这种情况之前一切正常。

删除InitializeComponent();中的runTimer。它应该在构造函数中调用一次。

您当前的流程是：

appendChar - ＆gt; runTimer - ＆gt;的InitializeComponent

C＃ - 菜单条复制无明显原因
