c# - 字符串未被识别为有效的 DateTime，asp.net

Question

,你好,

我有一个 asp.net 和 c# 网站。

在我使用的asp代码中

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"></asp:ScriptManager>

当我运行我的项目时，我得到这个错误:

String was not recognized as a valid DateTime.

我没有在我的网站上使用任何 dataTime 东西。

然后，当我刷新页面时，错误消失了。

堆栈跟踪:

可能是什么问题？

Answer 1

您正在使用传递给它的无效日期的 [TypeLibraryTimeStampAttribute] 引用一个库。

找到那个库并修复或删除它。

一般来说，在 ASP.Net 中使用 WinForms 库是个坏主意。
