ConnectionManager-Member

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.

Der ConnectionManager-Typ macht die folgenden Member verfügbar.

Methoden

	Name	Beschreibung
	AcquireConnection	Creates an instance of the connection type.
	Dispose	Releases the resources used by the ConnectionManager.
	Equals	Determines whether two object instances are equal. (Geerbt von DtsObject.)
	Finalize	(Geerbt von Object.)
	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. (Geerbt von DtsObject.)
	GetPackagePath	Gets or sets the path of the package that the connection applies to.
	GetType	(Geerbt von Object.)
	LoadFromXML	This method is not callable by your application code. To load a package that has been saved as .xml, use the Application..::..LoadPackage method.
	MemberwiseClone	(Geerbt von Object.)
	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 nullNothingnullptrunitein NULL-Verweis (Nothing in Visual Basic) 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	(Geerbt von Object.)
