This constructor creates a Uri instance from a URI string. It parses the URI, puts it in canonical format, and makes any required escape encodings.
This constructor assumes that the string parameter references an absolute URI and is equivalent to calling the Uri constructor with UriKind set to Absolute. If the string parameter passed to the constructor is a relative URI, this constructor will throw a UriFormatException.
The uriString can be poorly formed and can still be used to construct a Uri instance. The Silverlight runtime will try to correct some minor issues with a poorly-formed string when this constructor is called to create a Uri instance.
This constructor allows a Silverlight application to create a Uri instance for many schemes as described in the Scheme property. However, only Uri instances for the UriSchemeHttp or UriSchemeHttps schemes are supported by the WebClient and HTTP classes in the System.Net namespace.
This constructor does not ensure that the Uri refers to an accessible resource.
Silverlight-based applications are cross-platform, so they run in most modern Web browsers, including Apple Safari version 2.0 and later on Apple Mac OS X. However, does not convert backslashes in the uriString parameter to forward slashes in the Uri on Apple Mac OS X.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
