Assembly: System (in system.dll)
Property ValueA String containing the exact URI specified when this instance was constructed; otherwise, Empty.
This instance represents a relative URI, and this property is valid only for absolute URIs.
If the URI specified to the constructor contained leading or trailing spaces, these spaces are preserved.
When International Resource Identifier (IRI) and Internationalized Domain Name (IDN) support are enabled, OriginalString returns the original non normalized string with Punycode host name if one was used to initialize the Uri instance. Punycode names contain only ASCII characters and always start with the xn-- prefix.
For more information on IRI support, see the Remarks section for the Uri class.
The following example creates a new Uri instance from a string. It illustrates the difference between the value returned from OriginalString, which returns the string that was passed to the constructor, and from a call to ToString, which returns the canonical form of the string.
// Create a new Uri from a string address. Uri uriAddress = new Uri("HTTP://www.ConToso.com:80//thick%20and%20thin.htm"); // Write the new Uri to the console and note the difference in the two values. // ToString() gives the canonical version. OriginalString gives the orginal // string that was passed to the constructor. // The following outputs "http://www.contoso.com/thick and thin.htm". Console.WriteLine(uriAddress.ToString()); // The following outputs "HTTP://www.ConToso.com:80//thick%20and%20thin.htm". Console.WriteLine(uriAddress.OriginalString);
