如何阻止 asp.net 尝试加载共享点？答案

【问题标题】：How to stop asp.net from trying to load sharepoint?如何阻止 asp.net 尝试加载共享点？

【问题描述】：

我有一个充当代理的 ASP.net 表单页面。

我的网站正在从另一个网站 companyX.com 下载一些内容。

companyX.com 的网站正在使用 sharePoint。

我的网站正在从 companyX.com 下载 HTML 并成功将其添加到我的页面，但是，在 Page_Init, Page_Load 和 Page_Unload 之后但在 Render 之前，我的页面抛出粘贴在下面的错误。

我的站点没有安装任何共享点。但是，asp.net 中似乎有一些东西正在处理我页面中的 HTML 内容，识别一些共享点标签，然后尝试加载共享点。我很想把它关掉！

我的页面确实有EnableViewState="false" EnableViewStateMac="false" ValidateRequest="false"

错误：

【问题讨论】：

我将添加到 web.congig。仍然得到同样的错误。还覆盖了页面的 Validate 功能，但这没有效果。我怎样才能真正禁用视图状态？

标签： asp.net .net sharepoint

【解决方案1】：

ASP.net 没有绑定加载 Sharepoint，它试图理解您正在检索的页面中包含的 ViewState，但不能，因为它是由具有不同机器密钥等的另一台服务器构建的。

我会在渲染阶段之前亲自从检索到的 HTML 中删除 ViewState 隐藏字段，否则您可能会遇到持续存在的问题，这些问题可能会随机混淆问题。

【讨论】：

感谢 Moo 的反馈。我宁愿不删除视图状态数据。无论如何我可以告诉asp.net将页面视为文本而不尝试解析视图状态吗？此外，如果它没有尝试加载共享点，为什么会出现错误： FileNotFoundException：无法加载文件或程序集 'Microsoft.SharePoint

【解决方案2】：

我终于通过在我的页面中添加以下内容来修复它：

Protected Overrides Function LoadPageStateFromPersistenceMedium() As Object
    Return Nothing
End Function
