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

'Declaration
Public Property Connect As String
'Usage
Dim instance As WebPermissionAttribute 
Dim value As String 

value = instance.Connect

instance.Connect = value

Property Value

Type: System.String
A string containing the URI connection controlled by the current WebPermissionAttribute.

ExceptionCondition
ArgumentException

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

When applying WebPermissionAttribute to your class, this property specifies what URI connection is accepted for use within your class. This property is write-once.

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


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


Public Shared Sub demoDenySite()
   'Pass the security check.
   CheckConnectPermission("http://www.contoso.com/Public.htm")
   Console.WriteLine("Public page has passed Connect permission check")
   Try 
      'Throw a SecurityException.
      CheckConnectPermission("http://www.contoso.com/Private.htm")
      Console.WriteLine("This line will not be printed")
   Catch e As SecurityException
      Console.WriteLine(("Expected exception" + e.Message))
   End Try 
End Sub 'demoDenySite
// Set the WebPermissionAttribute  Connect property.
[method:WebPermission(SecurityAction::Deny, Connect=S"http://www.contoso.com/Private.htm")]
static void demoDenySite() {
   //Pass the security check.
   CheckConnectPermission(S"http://www.contoso.com/Public.htm");
   Console::WriteLine(S"Public page has passed connect permission check");

   try {
      //Throw a SecurityException.
      CheckConnectPermission(S"http://www.contoso.com/Private.htm");
      Console::WriteLine(S"This line will not be printed");
   } catch (SecurityException* e) {
      Console::WriteLine(S"Expected exception {0}", e->Message);
   }
}

static void CheckConnectPermission(String* uriToCheck) {
   WebPermission* permissionToCheck = new WebPermission();
   permissionToCheck->AddPermission(NetworkAccess::Connect, uriToCheck);
   permissionToCheck->Demand();
}
