Méthodes
Nom | Description | |
---|---|---|
AcquireConnection | Creates an instance of the connection type. | |
CanUpdate | Gets or sets a Boolean that determines whether a connection manager supports upgrading the connection XML to a newer version. | |
Equals | Determines whether two object instances are equal. (hérité de DtsObject.) | |
Finalize | (hérité de Object.) | |
GetHashCode | Returns the hash code for this instance. (hérité de DtsObject.) | |
GetType | (hérité de Object.) | |
MemberwiseClone | (hérité de Object.) | |
ReleaseConnection | Frees the connection established during AcquireConnection. Called at design time and run time. | |
SetQualifier | Changes a qualifier on the connection manager after the connection manager has been created, but before it is run. | |
ToString | (hérité de Object.) | |
Update | Updates the XML persisted by a previous version of the connection manager. | |
Validate | Validates the connection and returns an enumeration that indicates success or failure. |

Notes
You create a managed connection manager by deriving a managed class from the ConnectionManagerBase, and then marking it with DtsConnectionAttribute attribute.
When creating a managed connection manager, you must ensure that the threading model is Both for the connection manager to work properly with the Integration Services runtime.
