PackUriHelper.ComparePartUri Method

.NET Framework 4.5

Other Versions

Returns a value that indicates whether two package part URIs are equivalent.

Namespace: System.IO.Packaging
Assembly: WindowsBase (in WindowsBase.dll)

Syntax

C++

public static int ComparePartUri(
	Uri firstPartUri,
	Uri secondPartUri
)

Parameters

firstPartUri: Type: System.Uri
The URI of the first PackagePart.

secondPartUri: Type: System.Uri
The URI of the second PackagePart.

Return Value

Type: System.Int32
A value that indicates the relationship between firstPartUri and secondPartUri.

Value	Meaning
Less than 0	firstPartUri is less than secondPartUri.
0	firstPartUri is equivalent to secondPartUri.
Greater than 0	firstPartUri is greater than secondPartUri.

Exceptions

Exception	Condition
ArgumentException	firstPartUri or secondPartUri is not a valid part URI syntax.

Remarks

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.
