WebPermissionAttribute.Connect Property

Gets or sets the URI connection string controlled by the current WebPermissionAttribute.

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

public function get Connect () : String 
public function set Connect (value : String)

Property Value

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


Connect is not a null reference (Nothing in Visual Basic) 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.

No code example is currently available or this language may not be supported.
// Set the WebPermissionAttribute  Connect property.
[method:WebPermission(SecurityAction::Deny, Connect=S"")]
static void demoDenySite() {
   //Pass the security check.
   Console::WriteLine(S"Public page has passed connect permission check");

   try {
      //Throw a SecurityException.
      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);
