SocketPermission::ConnectList Property

Gets a list of EndpointPermission instances that identifies the endpoints that can be connected to under this permission instance.

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

public:
property IEnumerator^ ConnectList {
	IEnumerator^ get ();
}

Property Value

Type: System.Collections::IEnumerator
An instance that implements the IEnumerator interface that contains EndpointPermission instances.

The following example uses the ConnectList property to return a list of endpoints to which connection privileges are granted.
