The Uri and UriBuilder classes both represent a Uniform Resource Identifier (URI). Instances of the Uri type are immutable: once the underlying URI is specified, neither it nor its components, or constituent parts, can be changed. The UriBuilder type permits modifications to the components of the URI it represents. The UriBuilder.Uri property provides the current contents of a UriBuilder as a Uri instance.

All public static members of this type are safe for multithreaded operations. No instance members are guaranteed to be thread safe.
