WebPermission Constructor (NetworkAccess, Regex)

Initializes a new instance of the WebPermission class with the specified access rights for the specified URI regular expression.

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

public function WebPermission(
	access : NetworkAccess, 
	uriRegex : Regex
)

Parameters

access
Type: System.Net.NetworkAccess

A NetworkAccess value that indicates what kind of access to grant to the specified URI. Accept indicates that the application is allowed to accept connections from the Internet on a local resource. Connect indicates that the application is allowed to connect to specific Internet resources.

uriRegex
Type: System.Text.RegularExpressions.Regex

A regular expression that describes the URI to which access is to be granted.

This constructor initializes a WebPermission and grants its target permission to either make a remote host connection or accept a remote host connection using the URI described by the uriRegex parameter.

NoteNote:

It is recommended that you create uriRegex using the RegexOptions.IgnoreCase, RegexOptions.Compiled, and RegexOptions.Singleline flags.

NoteNote:

A candidate URI string is checked against the list of relevant regular expressions (AcceptList or ConnectList) in two ways. First, the candidate URI string is checked against the appropriate list; then, if there is no match, the candidate URI string is converted into a Uri and checked against the appropriate list.

The following example creates a new instance of WebPermission with connect rights for the specified System.Text.RegularExpressions.Regex.

No code example is currently available or this language may not be supported.
// Create an instance of 'Regex' that accepts all  URL's containing the host
// fragment 'www.contoso.com'.
Regex* myRegex = new Regex(S"http://www.contoso.com/.*");

// Create a WebPermission that gives the permissions to all the hosts containing
// the same fragment.
WebPermission* myWebPermission = new WebPermission(NetworkAccess::Connect, myRegex);

// Checks all callers higher in the call stack have been granted the permission.
myWebPermission->Demand();
