我试图通过在代码中输入事件来使日历正常工作。我对ASP.NET还不熟悉，所以我不知道如何解决这个问题。我一直得到的错误是：“事件”不包含一个带7个参数的构造函数。事件错误：参考事件构造函数

anEvent[1] = new Event("Event2", "Event two", "08/15/2014", "80.00", "Cathryn", "555-555-5555", "[email protected]");
anEvent[2] = new Event("Event3", "Event three", "09/05/2014", "50.00", "Charles", "888-888-8888", "[email protected]");

错误很明显 - “Event”类没有一个构造函数需要7个参数。发布'Event'的代码（如果它是你自己的课程），我们可以告诉你更多。 – Tim 2014-09-28 20:03:05

我不太确定要发布哪些代码。我是否发布主aspx页面？ – 2014-09-28 20:12:53
