我試圖通過遷移更新我的數據庫。 當我手工刪除所有表格然後用手重新創建時，我可能會搞砸了。EF遷移：參數@objname不明確或聲明的@objtype（COLUMN）錯誤
我使用代碼首先，和Add-遷移命令給了我這個：

}
我用括號（「[」和「]」），這顯然幫助了一些人在周圍每一個名字我的情況。 我發佈是因爲，你猜對了，它不適合我。
我總是得到：
無論是參數@objname不明確或所要求的@objtype（列）是錯誤的。
會有人有一個關於什麼是不能更新我的數據庫，禁止我猜？我應該從另一個項目重新開始嗎？
謝謝！
編輯：評論poiting我的支架放置在錯誤的方式後，我更新爲：

這並不遺憾的是解決我的問題。
您的括號內容不正確。例如'[dbo.Users]'應該是'[dbo]。[Users]' – DavidG
哦，這很有道理，我會嘗試。謝謝 ！ –
沒有運氣，沒有改變我的問題。感謝您的嘗試。 –
