我是這個世界的新手,坦率地說,我不喜歡它的複雜性,除此之外怎麼樣。連接到.sdf
我創建了一個名爲Sample.sdf
的新數據庫,然後我創建了一個新的ASP.NET MVC3應用程序。我在讀,你必須將.sdf
數據庫複製到項目的根目錄。所以我這樣做了,我試圖創建一個新的ADO.net連接到這個緊湊的數據庫,但我應該這樣做嗎?
我不能在web.config中使用連接字符串對象並將其配置爲指向該數據庫嗎?如果有,有沒有辦法測試連接?
我很好奇,因爲我打算在實體框架中使用它。
更新:
所以我想通了一些東西出來:
其中.sdf
已進入App_Data
文件夾,然後從他們的基礎上創建的一個ADO.net實體模型現有數據庫。它會自動查看數據庫,併爲您完成剩下的工作,或者至少在我的情況下它已經完成。
然而,它拋出一個錯誤,當點擊下一個實體數據模型嚮導,艇員選拔我的數據連接後,我得到了:
Unable to create new database.

我真的不知道如何着手。
發生'SqlException'是因爲您嘗試使用* full-blown * SQL Server類連接到您的SQL Server ** Compact **數據庫 - 這是行不通的。當你創建實體數據模型時,你沒有選擇'SQL Server Compact'作爲你的數據庫類型,或者你的連接字符串被其他方式弄壞了。 – 2013-04-10 16:12:23
