ExceptionCondition
ArgumentException

firstPartUri or secondPartUri is not a valid part URI syntax.

If both firstPartUri and secondPartUri are null, ComparePartUri returns 0. When comparing PackagePart URIs, a null URI is always less than a non-null URI. For cases where firstPartUri and secondPartUri are both relative PackagePart URIs, ComparePartUri performs the comparison.
