Hinweise
The ExtendedProperties collection lets custom information be stored with a package. For example, SSIS Designer itself stores package layout information in extended properties. Although the extended properties of the package are hidden at design time and ignored at run time, they are persisted with the package and provide a convenient way to attach user-defined information or metadata to a package for possible use by an automated process or custom tool.
Each ExtendedProperty has a Name, a Description, a DataType, and a Value. Use the ExtendedProperties property of the Package to access its extended properties collection, and use the Add method of the collection to add a new extended property.
