WebPermission::AddPermission Method (NetworkAccess, String)

Adds the specified URI string with the specified access rights to the current WebPermission.

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

void AddPermission(
	NetworkAccess access, 
	String^ uriString


Type: System.Net::NetworkAccess

A NetworkAccess that specifies the access rights that are granted to the URI.

Type: System::String

A string that describes the URI to which access rights are granted.


uriString is nullptr.

If you have specified None as the PermissionState, use AddPermission to permit the use of uriString in the target class. The way that uriString can be used by the target class is specified by access. Specify Accept as the access parameter to add the URI specified by the uriString parameter to the list of URI accept strings, or specify Connect as the access parameter to add the URI to the list of URI connect strings.


Calling AddPermission on Unrestricted WebPermission will have no effect, because permission is granted to all URIs.


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 demonstrates how to add access rights to particular URL strings.

// Allow access to the first set of resources.
myWebPermission1->AddPermission( NetworkAccess::Connect, "http://www.contoso.com/default.htm" );
myWebPermission1->AddPermission( NetworkAccess::Connect, "http://www.adventure-works.com/default.htm" );

// Check whether if the callers higher in the call stack have been granted 
// access permissions.
// Allow access to the first set of resources.

// Check whether if the callers higher in the call stack have been granted
// access permissions.
