asp.net - ASP.NET 中的奇怪错误

Question

每隔一段时间，我的 asp.net 应用程序就会出现大约 10 - 20 个相同的错误。它总是一样的，我想知道是否有人试图入侵(大约每月发生一次)。

Source: System.Web

Message: The file '/~/Default.aspx' does not exist.

User IP: 89.122.29.80

User Browser: Unknown 0.0

User OS: Unknown

为什么会有人试图访问 "/~/Default.aspx"？

如果您在页面生命周期中太晚尝试在 HyperLink 控件上设置 NavigateUrl，有时会发生这种情况。确保在生成相关 Url 后，您没有在代码中创建超链接。
