項目突然無法構建，錯誤為 0 Xamarin.Forms

Question

我已經在這個項目上工作了大約一個星期，沒有任何構建問題，但突然我的項目無法構建，屏幕上顯示 0 錯誤，但我在輸出窗口中發現了這 2 個警報。 我該如何解決？

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

我已經修復了這個問題“CSC : error CS0006: Metadata file 'C:\\Users\\Lenovo\\source\\repos\\Project11\\Project11\\Project11\\bin\\Debug
找不到 netstandard2.0\\ref\\Project11.dll'”

Visual Studio 沒有向我顯示任何錯誤，但是當我一一瀏覽 PageView 時，我注意到我的“Click_Event_Button”之一在 xaml.cs 文件中的名稱不正確。

希望這可以幫助遇到相同問題的其他用戶。
