Uri Constructor (String, UriKind)

Initializes a new instance of the Uri class with the specified URI. This constructor allows you to specify if the URI string is a relative URI, absolute URI, or is indeterminate.

Namespace:  System
Assembly:  System (in System.dll)

public Uri(
	string uriString,
	UriKind uriKind
)

Parameters

uriString
Type: System.String
A string that identifies the resource to be represented by the Uri instance.
uriKind
Type: System.UriKind
Specifies whether the URI string is a relative URI, absolute URI, or is indeterminate.

ExceptionCondition
ArgumentException

uriKind is not valid (possible values are Absolute, Relative, or RelativeOrAbsolute).

ArgumentNullException

uriString is null.

UriFormatException

uriString contains a relative URI and uriKind is Absolute.

or

uriString contains an absolute URI and uriKind is Relative.

Relative and absolute URIs have different restrictions on their format. For example, a relative URI does not require a scheme or an authority. The value you specify in uriKind must match the type of URI passed in uriString. However, if RelativeOrAbsolute is specified, the URI string can be relative or absolute.

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 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, Uri(String, UriKind) does not convert backslashes in the uriString parameter to forward slashes in the Uri on Apple Mac OS X.


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