I'm using IRelationshipClass.DestinationClass to get an IObjectClass. From here, I want to be able to get the table name, but can only access the AliasName.
UPDATE Aughhh, after searching for ages, and not finding an answer, I ask the question here, only to find it twenty minutes later.
The IObjectClass can be cast to a IDataset, which has the Name property, which is not the same as AliasName. I should say thanks to Kirk, as it was some code he posted elsewhere that pointed me in the right direction.
