我在网络编程课程中，我们当前的任务必须使用ASP.Net完成。我沮丧的问题和原因是由于我的教授缺乏教学，方向不明确，以及过时的“指南”。我正在使用2012版的Visual Studio Ultimate。
我应该制作一个完全不同的程序，而不是这个“指南”，但我不知道当我将所有这些错误/警告完全按照他的指南显示时，我应该怎么做。
在他写得不好的指南中......他说：“在调试时会出现一些错误。修复它们，你的网页就会显示出来。”然而，使用他的代码并遵循他所做的一切......我有52个错误和3个警告。我在Google上搜索了大部分内容，并且只为其他人的程序找到了Q＆amp; A特定问题。
没有太多的代码，我不知道复制我的教授代码/指南有多少错误。我将添加一些错误/警告，然后从下面的文件中添加代码。如果有人可以帮我解决其中的一些错误，我会非常感激。谢谢！

答案 0 :(得分：0)
这里缺少一些代码，等等。
代码隐藏类 - game.aspx.vb - 在game.aspx顶部的页面声明中引用： -
CodeFile="game.aspx.vb" Inherits="game"
但是game.aspx.vb中的类被称为customer？这不行。页面声明的“继承”部分清楚地表明它正在寻找一个名为“游戏”的类。
此外，您的一堆错误与IHttpHandler实现有关： -
Error 3 Class 'game_aspx' must implement 'ReadOnly Property IsReusable As Boolean' for interface 'System.Web.IHttpHandler'... (snip)
显然，这些是在一个名为game_aspx的课程中，而不是你发布的任何内容。
在您了解事情如何正常运作之前，您的讲师正试图让您解决愚蠢和令人困惑的问题。这是一种愚蠢的教学方式，特别是当他向你展示你可能以前从未见过的一大堆概念时。
我为你感到难过。没有人应该遭受如此低质量的教学。
无论如何 - 如果你能挖掘出其余的代码并发布它，我也许可以提供帮助。
