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.
