Remarks
The design of the IMetaDataImport interface is intended primarily to be used by tools and services that will be importing type information (for example, development tools) or managing deployed components (for example, resolution/activation services). The methods in IMetaDataImport fall into the following task categories:
Enumerating collections of items in the metadata scope.
Finding an item that has a specific set of characteristics.
Getting properties of a specified item.
The Get methods are specifically designed to return single-valued properties of a metadata item. When the property is a reference to another item, a token for that item is returned. Any pointer input type can be NULL to indicate that the particular value is not being requested. To obtain properties that are essentially collection objects (for example, the collection of interfaces that a class implements), use the enumeration methods.
