System_CAPS_noteNote

The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Creates a new instance of the WebPermission class that passes all demands or fails all demands.

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

Public Sub New (
	state As PermissionState
)

The value of the state parameter is either PermissionState.None or PermissionState.Unrestricted, respectively yielding fully restricted or fully unrestricted access to all security variables. If you specify PermissionState.None, then you can give access to individual URIs using AddPermission.

The following example creates an instance of WebPermission and gives access rights to specific URLs.

' Create a WebPermission instance.  
Dim myWebPermission1 As New WebPermission(PermissionState.None)

' Allow access to the first set of URL's.
myWebPermission1.AddPermission(NetworkAccess.Connect, "http://www.microsoft.com/default.htm")
myWebPermission1.AddPermission(NetworkAccess.Connect, "http://www.msn.com")

' Check whether all callers higher in the call stack have been granted the permissionor not.
myWebPermission1.Demand()
