A collection of all the package-level relationships that are contained in the package.

Exception typeCondition

ObjectDisposedException

The package is not open (Dispose or Close has been called).

IOException

The package is write-only.

GetRelationships will never return a null reference (Nothing in Visual Basic); however the returned collection may contain zero elements if the package contains no package-level relationships.

A package-level relationship defines an association between the package and an associated target part or resource. A package-level relationship can be one of two forms.

  • Between a Package to a target part in the package.

  • Between a Package to a target resource outside the package.

In a package-relationship the package is considered the "owner" of the relationship. When the package is deleted, all the relationships owned by the package are also deleted. The process of creating or deleting the relationship does not physically alter the target part or resource in any way.

For additional information about packaging and package relationships see section 1.3 of the Open Packaging Conventions (OPC) specification available for download at http://go.microsoft.com/fwlink/?LinkID=71255.
