 ## Remarks
  A URI is a compact representation of a resource available to your application on the intranet or internet. The <xref:System.Uri> class defines the properties and methods for handling URIs, including parsing, comparing, and combining. The <xref:System.Uri> class properties are read-only; to create a modifiable object, use the <xref:System.UriBuilder> class.
 
- Relative URIs (for example, "/new/index.htm") must be expanded with respect to a base URI so that they are absolute. The <xref:System.Uri.MakeRelative%2A> method is provided to convert absolute URIs to relative URIs when necessary.

  The <xref:System.Uri> constructors do not escape URI strings if the string is a well-formed URI including a scheme identifier.
