Public Shared Function ComparePackUri (firstPackUri As Uri, secondPackUri As Uri) As Integer

Parameters

firstPackUri

Uri

The first pack URI.

secondPackUri

Uri

The second pack URI.

Returns

Int32

A signed integer indicating the relationship between firstPackUri and secondPackUri.

Value	Meaning
Less than 0	firstPackUri is less than secondPackUri.
0	firstPackUri is equivalent to secondPackUri.
Greater than 0	firstPackUri is greater than secondPackUri.

Exceptions

ArgumentException

Either firstPackUri or secondPackUri is not an absolute URI.

-or-

Either firstPackUri or secondPackUri do not begin with a "pack://" scheme.

Remarks

If both firstPackUri and secondPackUri are null, ComparePackUri returns 0. When comparing pack URIs, a null URI is always less than a non-null URI. For cases where firstPackUri and secondPackUri are both absolute pack URIs, ComparePackUri performs the comparison.
