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

Quote：

| 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");
