C# 在ConnectionInfo中使用Web.Config的连接字符串

我想在我的类代码中使用Web.Config文件中定义的连接字符串，该类代码使用

ConnectionInfo

关键字

我已在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>

但是我想从定义在Web.Config文件中的连接字符串中使用它。

这会帮助您：

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;

然后在您的

连接信息中

：

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

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