Namespace: System
Assembly: System (in System.dll)

Syntax

'Declaration
Public Shared Function Compare ( _
    uri1 As Uri, _
    uri2 As Uri, _
    partsToCompare As UriComponents, _
    compareFormat As UriFormat, _
    comparisonType As StringComparison _
) As Integer

public static int Compare(
    Uri uri1,
    Uri uri2,
    UriComponents partsToCompare,
    UriFormat compareFormat,
    StringComparison comparisonType
)

Parameters

uri1
Type: System.Uri
The first Uri.

uri2
Type: System.Uri
The second Uri.

partsToCompare
Type: System.UriComponents
A bitwise combination of the UriComponents values that specifies the parts of uri1 and uri2 to compare.

compareFormat
Type: System.UriFormat
One of the UriFormat values that specifies the character escaping used when the URI components are compared.

comparisonType
Type: System.StringComparison
One of the StringComparison values.

Return Value

Type: System.Int32
An Int32 value that indicates the lexical relationship between the compared Uri components.

Value	Meaning
Less than zero	uri1 is less than uri2.
Zero	uri1 equals uri2.
Greater than zero	uri1 is greater than uri2.

Exceptions

Exception	Condition
ArgumentException	comparisonType is not a valid StringComparison value.

Remarks

If both uri1 and uri2 are nulla null reference (Nothing in Visual Basic), this method returns 0. When comparing URI values, a relative URI is always less than an absolute URI, and a non-null URI is always greater than a null URI. For cases where both uri1 and uri2 are not nulla null reference (Nothing in Visual Basic) and are both relative URIs or both absolute URIs, the String.Compare(String, String, StringComparison) method performs the comparison.
