WebPermission Constructor (NetworkAccess, Regex^)
Initializes a new instance of the WebPermission class with the specified access rights for the specified URI regular expression.
Assembly: System (in System.dll)
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 uriRegexparameter.
Note |
|---|
It is recommended that you create uriRegex using the RegexOptions::IgnoreCase, RegexOptions::Compiled, and RegexOptions::Singleline flags. |
Note |
|---|
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.
// Create an instance of 'Regex' that accepts all URL's containing the host // fragment 'www.contoso.com'. Regex^ myRegex = gcnew Regex( "http://www.contoso.com/.*" ); // Create a WebPermission that gives the permissions to all the hosts containing // the same fragment. WebPermission^ myWebPermission = gcnew WebPermission( NetworkAccess::Connect,myRegex ); // Checks all callers higher in the call stack have been granted the permission. myWebPermission->Demand();
