无法打开登录'Database1'中请求的数据库。登录失败。用户'sa'登录失败

Question

当我将我的web应用程序部署到Windows Server 2003时，出现了上述错误。我该如何解决？

Login.aspx.vb

Dim connection As String = System.Configuration.ConfigurationManager.ConnectionStrings("database").ConnectionString() 

Dim mycon As New SqlConnection(connection) 

的Web.config

<connectionStrings> 
    <add name="database" connectionString="Data Source='172.20.145.67';Initial Catalog='Database1';User ID='sa';Password='321'"/> 
</connectionStrings>

Answer 1

您不需要在连接字符串内引用字符串。

<add name="database" connectionString="Data Source=172.20.145.67;Initial Catalog=Database1;User ID=sa;Password=321"/>

Answer 2

试试这个

<add name="database" connectionString="Data Source=172.20.145.67;Initial Catalog=Database1;User ID=sa;Password=321"/> 

删除单引号
