.NET Framework 4.5

Other Versions

Note: This API is now obsolete.

Determines the difference between two Uri instances.

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

Syntax

C++

[ObsoleteAttribute("The method has been deprecated. Please use MakeRelativeUri(Uri uri). http://go.microsoft.com/fwlink/?linkid=14202")]
public string MakeRelative(
	Uri toUri
)

Parameters

toUri: Type: System.Uri
The URI to compare to the current URI.

Return Value

Type: System.String
If the hostname and scheme of this URI instance and toUri are the same, then this method returns a String that represents a relative URI that, when appended to the current URI instance, yields the toUri parameter.
If the hostname or scheme is different, then this method returns a String that represents the toUri parameter.

Exceptions

Exception	Condition
ArgumentNullException	toUri is null.
InvalidOperationException	This instance represents a relative URI, and this method is valid only for absolute URIs.

Remarks

The following table shows the URI instance, toUri, and the results of calling MakeRelative.

Current URI instance	toUri	Return value
http://www.contoso.com/	http://www.contoso.com/test/test.htm	test/test.htm
http://www.contoso.com/test1/	http://www.contoso.com/	../
http://www.contoso.com:8000/	http://www.contoso.com/test/test.htm	http://www.contoso.com/test/test.htm
http://username@www.contoso.com/	http://www.contoso.com/test1/test1.txt	test1/test1.txt

User information, if present in the URI, is ignored.

Examples

The following example creates 2 Uri instances. The difference in the path information is written to the console.

C++

// Create a base Uri.
Uri address1 = new Uri("http://www.contoso.com/");

// Create a new Uri from a string.
Uri address2 = new Uri("http://www.contoso.com/index.htm?date=today"); 

// Determine the relative Uri.  
Console.WriteLine("The difference is {0}", address1.MakeRelativeUri(address2));
