Question

我目前正在完成本教程 - https://www.asp.net/web-forms/overview/getting-started/getting-started-with-aspnet-45-web-forms/introduction-and-overview

一切正常，但是当我将其复制并粘贴到那里时，一页填充错误。本教程是在Visual Studio 2013中完成的，我在2015年，但我认为不会产生那么大的差异，我假设语法保持不变。这是我粘贴446错误时的代码 -

Answer 1

复制代码时似乎存在问题，因为它将描述字段拆分为多行，这就是您看到错误的原因。

您可以尝试这样，它仍然允许多行

  Description = @"This convertible car is fast! The engine is
    powered by a neutrino based battery (not included).
    Power it up and let it go!"

Answer 2

万一其他人需要这个。粘贴它时，将描述放在两行上。如果你把描述放在一行上就行了。
