ConnectionManager 클래스

Provides the information that you must have to connect to a data source. All classes that inherit from the ConnectionManager contain the same properties and methods. The ConnectionManager class isolates the implementation details of the different connection types from the runtime. This enables the runtime to interact with each connection manager in a consistent and predictable manner. Connection managers contain a set of stock properties that all connections have in common, such as the Name, ID, Description, and ConnectionString. However, each connection type has additional properties that are specific to that connection type. These can be accessed through the Properties collection.This class cannot be inherited.

속성

	이름	설명
	ConnectionString	Gets or sets the connection string used to establish a connection to a data source.
	CreationName	Returns the string that is used by the runtime to create an instance of the ConnectionManager object and to add the object to the Connections collection. This property is read-only.
	DelayValidation	Gets or sets a Boolean that indicates whether package validation is delayed until the package runs.
	Description	Gets or sets the description of the ConnectionManager object.
	HasExpressions	Gets a value that indicates whether the connection manager has properties set through expressions.
	HostType	Gets an enumeration that describes the type of host that the connection is being used by. This property is read-only.
	ID	Gets the ID of the ConnectionManager. This property is read-only.
	InnerObject	Returns the specific connection type that was created. This property is read-only.
	Name	Gets or sets the name of the ConnectionManager object.
	OfflineMode	Gets or sets a value that indicates whether the connection manager is in offline mode.
	Properties	Gets a collection of property objects for the ConnectionManager. This is the method of accessing the properties of the specific connection that is being hosted by the connection manager. This property is read-only.
	ProtectionLevel	Gets or sets the level of encryption performed on sensitive data that is contained in the package.
	Qualifier	Gets or sets the qualifier for the connection manager.
	Scope	Gets the scope of the connection manager.
	Site	인프라입니다. Gets or sets the site of the connection manager.
	SupportsDTCTransactions	Returns a Boolean that indicates if the connection supports Microsoft Distributed Transaction Coordinator (MS DTC) transactions.
	VariableDispenser	Gets the dispenser of the variables in the connection manager.
	Variables	Gets the collection of variables in the connection manager.

	이름	설명
	AcquireConnection	Creates an instance of the connection type.
	Dispose	Releases the resources used by the ConnectionManager.
	Equals	Determines whether two object instances are equal. (DtsObject에서 상속됨)
	GetExecutionPath	Returns the execution path of the connection manager.
	GetExpression	Returns a String that contains the expression for the specified property. Null means that no expression has been assigned.
	GetHashCode	Returns the hash code for this instance. (DtsObject에서 상속됨)
	GetPackagePath	Gets or sets the path of the package that the connection applies to.
	GetType	(Object에서 상속됨)
	LoadFromXML(String, IDTSEvents)	This method is not callable by your application code. To load a package that has been saved as .xml, use the Application.LoadPackage method.
	LoadFromXML(XmlNode, IDTSEvents)	This method is not callable by your application code. To load a package that has been saved as .xml, use the Application.LoadPackage method.
	ReleaseConnection	Frees the connection established during AcquireConnection. Called at design time and runtime.
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.
	SetExpression	Assigns the specified expression to the property. Specify nullnull 참조(Visual Basic에서는 Nothing) to remove an existing expression from the property.
	SetQualifier	Changes a qualifier on the connection manager after the connection manager has been created but before it is used in a running package.
	ToString	(Object에서 상속됨)

주의

A connection manager is a logical representation of a connection. At design time, in the graphical user interface, you use a connection manager to describe the physical connection that the runtime creates when the package runs. Integration Services provides different types of connection managers that enable packages to connect to a variety of data sources. For example, there is an ActiveX Data Objects (ADO) connection manager, an ADO.NET connection manager, an ODBC connection manager, and so on. For more information, see 사용자 지정 개체를 사용한 패키지 확장.
