Question

我正在为一个项目创建一个网站，但不断收到此错误。网站的此部分是注册页面，访问者在此输入他们的信息，然后代码会将其写入我连接的数据库中。我正在使用Visual Studio，并且我的网页是.cshtml文件。我正在使用的execute命令如下：

 db.Execute(insertCommand, name, email, number, address, psw, psw_repeat);

这是完整的数据库代码：

@{
var name = "";
var email = "";
var number = "";
var address = "";
var psw = "";
var psw_repeat = "";

if (IsPost)
{
    name = @Request.Form["name"];
    email = @Request.Form["email"];
    address = @Request.Form["address"];
    psw = @Request.Form["psw"];
    psw = @Request.Form["psw_repeat"];

    var db = Database.Open("UserDetails");
    var insertCommand = "INSERT INTO [dbo.details] (Name, Email, Number, DeliveryAddress, Password, RepeatPassword) VALUES(@name, @email, @number, @address, @psw, @psw_repeat)";
    db.Execute(insertCommand, name, email, number, address, psw, psw_repeat);
}
}

当我尝试运行网页时，一切正常，我可以输入详细信息。当我单击提交按钮时，将显示此错误：

“ /”应用程序中的服务器错误。与网络相关或建立与以下对象的连接时发生特定于实例的错误 SQL Server。服务器未找到或无法访问。校验实例名称正确并且已将SQL Server配置为允许远程连接。（提供者：SQL网络接口，错误：26 -错误定位指定的服务器/实例）

此行以红色突出显示：

db.Execute(insertCommand, name, email, number, address, psw, psw_repeat);

我看过许多类似的问题，并尝试添加：

<system.web>
<customErrors mode="Off"/>

在我的web.config文件中，但这没有帮助。

请帮助我了解问题所在以及可能的解决方案。谢谢。

编辑：经过进一步研究，我尝试在Microsoft SQL Server Management Studio中打开数据库。输入服务器名称：“ RM48-11”时，我再次收到此错误：
