我已经在这个项目上工作了大约一个星期，没有任何构建问题，但突然我的项目无法构建，屏幕上显示 0 错误，但我在输出中发现了这 2 个警报 window.我该如何解决这个问题？

CSC : error CS0006: Metadata file
'C:\Users\Lenovo\source\repos\Project11\Project11\Project11\bin\Debug\
netstandard2.0\ref\Project11.dll' could not be found

Answer 1

我已修复此问题“CSC：错误 CS0006：元数据文件 'C:\Users\Lenovo\source\repos\Project11\Project11\Project11\bin\Debug
netstandard2.0\ref\Project11.dll' 无法找到

Visual Studio 没有显示任何错误，但是当我一个一个地浏览 PageView 时，我注意到我的“Click_Event_Button”中的一个 [=19] 的名称不正确=] 文件.

希望这对遇到同样问题的其他用户有所帮助。
