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.
Below programs illustrate the use of Uri.MakeRelativeUri(Uri) Method:
Example 1:
using System;
using System.Globalization;
class GFG {
public static void Main()
{
Uri uri = address1.MakeRelativeUri(address2);
Console.WriteLine( "relative uri is : {0}" , uri);
}
}
|
Output:
relative uri is : index.htm?date=today
Example 2: For ArgumentNullException
using System;
using System.Globalization;
class GFG {
public static void Main()
{
try {
Uri address2 = null ;
Uri uri = address1.MakeRelativeUri(address2);
Console.WriteLine( "relative uri is : {0}" , uri);
}
catch (ArgumentNullException e)
{
Console.WriteLine( "uri should not be null" );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
}
|
Output:
uri should not be null
Exception Thrown: System.ArgumentNullException
Example 3: For UriFormatException
using System;
using System.Globalization;
class GFG {
public static void Main()
{
try {
Uri uri = address1.MakeRelativeUri( new Uri( "http:://www.contoso.com/??index.htm?date=today" ));
Console.WriteLine( "relative uri is : {0}" , uri);
}
catch (ArgumentNullException e) {
Console.WriteLine( "uri should not be null" );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (UriFormatException e) {
Console.WriteLine( "uri should be in correct format" );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
}

Output:
uri should be in correct format
