推荐答案

您是否将项目创建为服务器场解决方案或沙箱解决方案?

Did you create your project as a Farm Solution or Sandbox Solution?

Microsoft.SharePoint.dll有两个版本.如果您在项目中引用的版本是14 \ UserCode \ assemblies，则您正在使用沙盒版本.沙箱解决方案中不提供LayoutsPageBase类.

There are two versions of Microsoft.SharePoint.dll. If the version you have referenced in your project is from 14\UserCode\assemblies, then you are using the sandbox version. The LayoutsPageBase class is not available in sandbox solutions.
