uriString is a null reference (Nothing in Visual Basic).

This constructor initializes a WebPermission and grants its target permission to either make a remote host connection or accept a remote host connection using the URI described by the uriString parameter.

The following example creates a new instance of WebPermission with connect rights for the specified URI.

// Create a WebPermission::instance.
WebPermission^ myWebPermission1 = gcnew WebPermission( NetworkAccess::Connect,"http://www.contoso.com/default.htm" );

// Create a WebPermission.instance.
WebPermission myWebPermission1 = new WebPermission(
    NetworkAccess.Connect, "http://www.contoso.com/default.htm");
