注解
连接字符串的格式和内容取决于要创建的数据提供程序、数据源和连接管理器的类型。 若要查看示例连接字符串，请在SQL Server Data Tools中创建包，然后在该包中创建相应类型的连接管理器。 接下来，在属性窗口中，检查ConnectionString刚刚创建的连接管理器的属性。
下面的代码示例添加一个 OLE DB 连接管理器，然后设置连接管理器名称和连接字符串属性。
// Add the OLE DB connection manager.
ConnectionManager adventureWorks = package.Connections.Add("OLEDB");
// Set stock properties.
adventureWorks.Name = "OLEDBConnection";
adventureWorks.ConnectionString = @"Provider=SQLNCLI10;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=AdventureWorks;Data Source=(local);Auto Translate=False;";
' Add the OLE DB connection manager.
Dim adventureWorks As ConnectionManager = package.Connections.Add("OLEDB")
' Set stock properties.
adventureWorks.Name = "OLEDBConnection"
adventureWorks.ConnectionString = "Provider=SQLNCLI10;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=AdventureWorks;Data Source=(local);Auto Translate=False;"
对于 XML 连接字符串，连接字符串值的格式类似于以下内容：
String myConnString = @"C:\Program Files\Microsoft SQL Server\orders.xml";
而对于 OLE DB 连接，连接字符串包含类似于以下连接字符串的值：
String myConnString = "Server=MYSERVER;Provider=SQLOLEDB.1;Pwd= xxxxxxx;User ID= xxxxx;Initial Catalog=mySource;OLE DB Services=-2";
ODBC 连接字符串可能如下所示：
String myConnString = "DSN=LocalServer;DATABASE=MySource;PWD=xxxxxxx;UID=xxxxx";
在 SSIS 设计器中连接的属性对话框中，此值显示为 连接字符串 属性。
