推荐答案

它位于Web应用程序的App_Data文件夹中 It is located in App_Data folder of your web application

它位于App_Data目录中。 您可以将AttachDBFilename更改为指向正确的文件夹。 例如AttachDBFilename = C：\\ \\ Database\aspdotnet.mdf It is located in App_Data directory. You can change AttachDBFilename to point to the right folder. For e.g AttachDBFilename=C:\Database\aspdotnet.mdf

| DataDirectory | 是替换字符串所以你可以单独配置数据库文件的位置。 所以代替：

|DataDirectory| is a substitution string so you can configure the location of your database file separately. So instead of:

SqlConnection c = new SqlConnection ( @"Data Source=.\SQLDB; AttachDbFilename=C:\MyDB\Database.mdf;Initial Catalog=Master");

您执行以下操作：

you do the following:

// Set |DataDirectory| value AppDomain.CurrentDomain.SetData("DataDirectory", "C:\myDB"); // SQL Connection String with |DataDirectory| substitution string SqlConnection c = new SqlConnection ( @"Data Source=.\SQLDB; AttachDbFilename=|DataDirectory|\Database.mdf;Initial Catalog=Master");
