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

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 */
public String get_Connect ()

/** @property */
public void set_Connect (String value)

public function get Connect () : String

public function set Connect (value : String)

Property Value

A string containing the URI connection controlled by the current WebPermissionAttribute.

Exception typeCondition

ArgumentException

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.


' 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.
/** @attribute WebPermission(SecurityAction.Deny, Connect = 
    "http://www.contoso.com/Private.htm")
 */
public static void 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 (SecurityException e) {
        Console.WriteLine("Expected exception" + e.get_Message());
    }
} //DemoDenySite

public static void CheckConnectPermission(String uriToCheck)
{
    WebPermission permissionToCheck = new WebPermission();
    permissionToCheck.AddPermission(NetworkAccess.Connect, uriToCheck);
    permissionToCheck.Demand();
} //CheckConnectPermission
