This constructor creates a Uri instance from a URI string. It parses the URI and puts it in canonical format.

The dontEscape parameter controls whether reserved characters are translated into escape sequences. This parameter should be set to true only if you are certain that all reserved characters in the URI have been escaped. Setting the value to true for a URI that has not been completely escaped can cause unexpected behavior. It is strongly recommended that you always set this parameter to false.

If dontEscape is set to false, the constructor escapes any reserved characters by checking that all occurrences of percent (%) are followed by a valid escape sequence. If the character sequence following a percent is not valid, the percent is replaced by %25.

This constructor does not ensure that the Uri refers to an accessible resource.

The following example creates a Uri instance for the URI http://www.contoso.com/Hello%20World.htm. Because the contained URI is completely escaped and is in canonical form, the dontEscape parameter can be set to true.

Uri myUri = new Uri("http://www.contoso.com/Hello%20World.htm", true);


Uri myUri = new Uri("http://www.contoso.com/Hello%20World.htm", true);

var myUri : Uri = new Uri("http://www.contoso.com/Hello%20World.htm", true);
