            {
                Console.WriteLine(idStrings[i]);
            }

        }

我在这里做错了什么？我评论了http 500.error处理请求的位置，但是我不知道如何修复它。该代码通过终端工作，但不能通过网页进行... ???

我可能会写很多东西，并且可能有一种更简单的方法，但是我以前没有在ASP.NET环境中工作，所以我是新手。

任何帮助将不胜感激！

另外，如果有人可以告诉我如何进行下一步获取输入并从艺术家搜索结果中获取ID，这也会有所帮助！

您的按钮没有绑定到它的单击事件，因此单击它永远不会触发button1Clicked。

<asp:Button id="button1" runat="server" Text="Search" OnClick="button1Clicked" />

，此行public static void Main(string[] args)没有参考文献(GetClientCredentialsAuthToken也是如此(，看起来像是winform方法。您确定您不混合WebForms和Winforms代码吗？
