在asp中有多种方法保存数据库连接串，asp+提供了另一种新方式:config.web。quickstart中的许多demo都是直接将连接串写在程序中。这对于demo用途是没有问题，但在实际使用中是不行的。<br> <br> 本文示范如何使用config.web来存储连接串。在每页asp.net中你只需用<br> 调出来就可以直接使用了。这样做的好处一是安全，二是方便，改密码时只需改一个地方即可。<br> <br> 废话少说，这里就是code:(放在该application的根目录下)<br> <br> Config.web<br> <configuration> <br> <appsettings><br> <add key="MyConn" value="server=localhost;uid=sa;pwd=mypassword;Database=somedatabase"/><br> </appsettings><br> </configuration><br> <br> <br> Somepage.aspx<br> <%@ Import Namespace="System.Data" %><br> <%@ Import Namespace="System.Data.SQL" %><br> <br> <script language="VB" runat="server"><br> <br> Sub Page_Load(Src As Object, E As EventArgs) <br> <br> 'This is the meat of calling the DSN out of the config.web<br> <br> 'Setting a local variable to hold the connection string variable<br> Dim MyConnection As SQLConnection<br> Dim Config as HashTable<br> <br> 'Setting a local variable to hold the connection string<br> Config = Context.GetConfig("appsettings")<br> MyConnection = New SQLConnection(Config("MyConn"))<br> <br> 'Setting a command object to insert some data into a database<br> Dim MyCommand As SQLCommand<br> <br> dim parm1 as string = "SomeTextValue"<br> dim parm2 as string = "SomeTextValue2"<br> <br> Dim InsertCmd As String = "Insert into tablename values (@parm1, @parm2)"<br> <br> 'Using the connection string<br> MyCommand = New SQLCommand(InsertCmd, MyConnection)<br> <br> MyCommand.Parameters.Add(New SQLParameter("@Parm1", SQLDataType.VarChar, 50))<br> MyCommand.Parameters("@Parm1").Value = Parm1<br> <br> MyCommand.Parameters.Add(New SQLParameter("@Parm2", SQLDataType.VarChar, 50))<br> MyCommand.Parameters("@Parm2").Value = Parm2<br> <br> MyCommand.ActiveConnection.Open()<br> MyCommand.Execute()<br> MyCommand.ActiveConnection.Close()<br> <br> End Sub<br> </script><br> <br> 讨饭猫 翻译自aspfree.com<br>
