Question

我从Godaddy购买了Windows“最终共享主机”。我已经上传了所有必需的文件，该站点正常工作。当我在myLittleAdmin上创建数据库并从中获取连接字符串时。我将该连接字符串放到了托管在godaddy上的web.config文件中，但是每当我从托管站点向数据库发送查询时，都会出错。该字符串确实可以在localhost上完美运行。

我只是不知道我做错了什么地方。

这是连接字符串：

<connectionStrings>
    <add name="GodaddyString" connectionString="Data Source=IP;Initial Catalog=db108;Integrated Security=False;User ID=USER;Password=PASS"
    providerName="System.Data.SqlClient" />
</connectionStrings>

这是Web.config文件：

<?xml version="1.0" encoding="utf-8"?>

当您的应用程序暂时托管在其他服务器和Godaddy数据库服务器上时，通常会发生此错误。
