我做了一个静态。
第一种形式是欢迎形式,包含2个县:登记和开始测试。 当你点点击启动试验时,纽特州的点击事件将使用该代码。
Quiz_interface obj1 = new Quiz_interface();
obj1.Visible = true;
打开显示问题的新表格。
现在的问题是:
如果在座右边部分加上另一个 but子或图像,则用该代码添加点击事件
result obj2 = new result();
obj2.Visible = true;
我收到这一错误<代码>。 无效行动 处理例外。 由于散列名称缺失,未能开始使用。
如何做到这一点?
我猜测,你的“结果”目标可能没有“可能”成员。
明确跨过浮桥,并核实其坠毁的正确线端。 如果是“obj2.Visible = 真的”,那么确保实际的切除率为has“Visible”。
