ConnectionManager-Klasse

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 folgende Elemente verfügbar.

Eigenschaften

  Name Beschreibung
Öffentliche Eigenschaft ConnectionString Gets or sets the connection string used to establish a connection to a data source.
Öffentliche Eigenschaft 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.
Öffentliche Eigenschaft DelayValidation Gets or sets a Boolean that indicates whether package validation is delayed until the package runs.
Öffentliche Eigenschaft Description Gets or sets the description of the ConnectionManager object.
Öffentliche Eigenschaft HostType Gets an enumeration that describes the type of host that the connection is being used by. This property is read-only.
Öffentliche Eigenschaft ID Gets the ID of the ConnectionManager. This property is read-only.
Öffentliche Eigenschaft InnerObject Returns the specific connection type that was created. This property is read-only.
Öffentliche Eigenschaft Name Gets or sets the name of the ConnectionManager object.
Öffentliche Eigenschaft 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.
Öffentliche Eigenschaft ProtectionLevel Gets or sets the level of encryption performed on sensitive data that is contained in the package.
Öffentliche Eigenschaft Site Infrastruktur
Öffentliche Eigenschaft SupportsDTCTransactions Returns a Boolean that indicates if the connection supports Microsoft Distributed Transaction Coordinator (MS DTC) transactions.

Methoden

  Name Beschreibung
Öffentliche Methode AcquireConnection Creates an instance of the connection type.
Öffentliche Methode Dispose Releases the resources used by the ConnectionManager.
Öffentliche Methode Equals Determines whether two object instances are equal. (Geerbt von DtsObject.)
Geschützte Methode Finalize (Geerbt von Object.)
Öffentliche Methode GetExpression Returns a String that contains the expression for the specified property. Null means that no expression has been assigned.
Öffentliche Methode GetHashCode Returns the hash code for this instance. (Geerbt von DtsObject.)
Öffentliche Methode GetPackagePath Gets or sets the path of the package that the connection applies to.
Öffentliche Methode GetType (Geerbt von Object.)
Öffentliche Methode 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.
Geschützte Methode MemberwiseClone (Geerbt von Object.)
Öffentliche Methode ReleaseConnection Frees the connection established during AcquireConnection. Called at design time and runtime.
Öffentliche Methode SaveToXML This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
Öffentliche Methode SetExpression Assigns the specified expression to the property. Specify nullNothingnullptrunitein NULL-Verweis (Nothing in Visual Basic) to remove an existing expression from the property.
Öffentliche Methode SetQualifier Changes a qualifier on the connection manager after the connection manager has been created but before it is used in a running package.
Öffentliche Methode ToString (Geerbt von Object.)

Hinweise

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 Extending Packages with Custom Objects.
