我正在一家新公司开始工作,我应该开始使用其他人在.net核心MVC中开发的系统。
我有数据库的本地副本和代码的本地副本。 我可以访问SQL Server数据库并在SQL Server 2014中发出自己的SQL请求,不幸的是,我无法将Visual Studio代码连接到我的数据库并使所有内容在本地运行。
我尝试加载“ Views \ Home \ Index.cshtml”,页面开始在“ localhost:45896”加载,几秒钟后出现以下错误:
似乎该路径未正确写入json文件中,但我不确定如何以其他方式写入它。
也许还有其他东西。
连接字符串:
“ ConnectionStrings”:{ “ DefaultConnection”:“服务器= / SQLExpress;数据库= something_article;用户 Id = admins; Password = Admin;“, “ EntityFrameworkConnection”:“数据源= 172.16.10.5;初始目录=公司名_通用;持久性安全信息= True;用户 id = admin; password = azerty; MultipleActiveResultSets = True; App = EntityFramework“” }
谢谢
最好的问候 瑞

在网络配置中添加连接字符串
在configuration
标记内
<connectionStrings>
<add name="connectionname"
connectionString="Server=localhost; Database=dbname;
Integrated Security=True"; providerName="System.Data.SqlClient" />
</connectionStrings>
并使用以下命令读取该连接字符串:-
System.Configuration.ConfigurationManager.
ConnectionStrings["connectionname"].ConnectionString;
