UrlIdentityPermission Constructor (String)

Initializes a new instance of the UrlIdentityPermission class to represent the URL identity described by site.

Namespace:  System.Security.Permissions
Assembly:  mscorlib (in mscorlib.dll)

public UrlIdentityPermission(
	string site
)

Parameters

site
Type: System.String

A URL or wildcard expression.

ExceptionCondition
ArgumentNullException

The site parameter is null.

FormatException

The length of the site parameter is zero.

ArgumentException

The URL, directory, or site portion of the site parameter is not valid.

The complete URL is considered, including the protocol (HTTP, HTTPS, FTP) and the file, for example: http://www.fourthcoffee.com/process/grind.htm/.

URLs can be matched exactly or by a wildcard in the final position, for example: http://www.fourthcoffee.com/process/*. URLs can also contain a wildcard ("*") prefix at the dot delimiter. For example, the URL name string http://www.fourthcoffee.com/process/grind.htm/ is a subset of http://*.fourthcoffee.com/process/grind.htm/ and http://*.com/process/grind.htm/.

NoteNote:

New in version 2.0, for performance reasons, an invalid URL does not cause an argument exception at the time the new class instance is created. The argument exception will occur when one of the set operations (Union, Intersect, or IsSubsetOf) is executed. A demand on the permission causes IsSubsetOf to be called by the security infrastructure. The demand will fail because of the argument exception, resulting in a SecurityException being thrown. In this case the original ArgumentException exception will not be seen.

The following code example shows the use of the UrlIdentityPermission.UrlIdentityPermission(String) constructor. This example is part of a larger example provided for the UrlIdentityPermission class.

UrlIdentityPermission permIdPerm1 = new UrlIdentityPermission("http://www.fourthcoffee.com/process/");
