WebPermissionAttribute.Accept Property

Gets or sets the URI string accepted by the current WebPermissionAttribute.

Namespace:  System.Net
Assembly:  System (in System.dll)
'Declaration
Public Property Accept As String

Property Value

Type: System.String
A string containing the URI accepted by the current WebPermissionAttribute.
ExceptionCondition
ArgumentException

Accept is not Nothing when you attempt to set the value. If you wish to specify more than one Accept URI, use an additional attribute declaration statement.

When applying WebPermissionAttribute to your class, this property specifies what URI string will be accepted for use within your class. This permission is applied when the security system calls CreatePermission. This property is write-once.

The following example demonstrates how to use WebPermissionAttribute to specify an allowable Accept string.


 ' Deny access to a specific resource by setting the Accept property.

<WebPermission(SecurityAction.Deny, Accept := "http://www.contoso.com/Private.htm")>  _
   Public Shared Sub CheckAcceptPermission(uriToCheck As String)
   Dim permissionToCheck As New WebPermission()
   permissionToCheck.AddPermission(NetworkAccess.Accept, uriToCheck)
   permissionToCheck.Demand()
End Sub 'CheckAcceptPermission


Public Shared Sub demoDenySite()
   ' Pass the security check when accessing allowed resources.
   CheckAcceptPermission("http://www.contoso.com/Public.htm")
   Console.WriteLine("Public page has passed Accept permission check")
   Try 
      'Throw a SecurityException when trying to access not allowed resources.
      CheckAcceptPermission("http://www.contoso.com/Private.htm")
      Console.WriteLine("This line will not be printed")
   Catch e As SecurityException
      Console.WriteLine(("Exception trying to access private resource:" + e.Message))
   End Try 
End Sub 'demoDenySite
