在 ConnectionInfo 中使用 Web.Config 的连接字符串

Question

我想在使用ConnectionInfo 关键字的类代码中使用定义在 Web.Config 文件中的连接字符串。

我在 Web.Config 文件中将我的连接字符串定义为::

 <connectionStrings>
  <add name="Connection_Report" connectionString="metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=servername;initial catalog=dbName;user id=username;password=password;multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>

在我的类代码中，我想将它用于ConnectionInfo 目前我必须在控制器中将其定义为::

ConnectionInfo ConnInfo = new ConnectionInfo { ServerName = "servername", UserID = "UserID", Password = "Password", DatabaseName = "DatabaseName" };

但我想从定义到 Web.Config 文件中的连接字符串中使用它。

这对您有帮助吗：

var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["yourConnectionString"].ConnectionString;

        SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(connectionString);
        string dbName = builder.InitialCatalog;
        string dbDataSource = builder.DataSource;
        string userId = builder.UserID;
        string pass = builder.Password;

然后在你的ConnectionInfo:

ConnectionInfo ConnInfo = new ConnectionInfo { ServerName = "dbDataSource", UserID = "userId", Password = "pass", DatabaseName = "dbName" };
