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)
'Declaration Public Sub New ( _ access As NetworkAccess, _ uriRegex As Regex _ )
- 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.
- 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.
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.
