C# | Uri.MakeRelativeUri(Uri) Method

Uri.MakeRelativeUri(Uri) Method is used to determine the difference between two Uri instances.

Syntax: public Uri MakeRelativeUri (Uri uri);
Here, it takes the URI to compare to the current URI.

Return Value: If the hostname and scheme of this URI instance and uri are the same, then this method returns a relative Uri that, when appended to the current URI instance, yields uri. If the hostname or scheme is different, then this method returns a Uri that represents the uri parameter.

Exceptions:

  • ArgumentNullException: If uri is null.
  • UriFormatException: If this instance represents a relative URI, and this property is valid only for absolute URIs.
