在ConnectionInfo中使用Web.Config的連接字符串

Question

我想在使用ConnectionInfo關鍵字的類代碼中使用Web.Config文件中定義的連接字符串。

我在Web.Config文件中將連接字符串定義為：

 <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>

在我的類代碼中，我想將其用於ConnectionInfo目前，我必須在conroller中將其定義為：

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

但是我想從連接字符串定義為Web.Config文件中使用它。

這會幫助您：

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ConnectionInfo ：

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