ISponsor Interface

Indicates that the implementer wants to be a lifetime lease sponsor.

Namespace: System.Runtime.Remoting.Lifetime
Assembly: mscorlib (in mscorlib.dll)

public interface class ISponsor
/** @attribute ComVisibleAttribute(true) */ 
public interface ISponsor
public interface ISponsor

An object must implement the ISponsor interface if it needs to request a lease renewal for a particular object. An object that implements the ISponsor interface can become a sponsor by registering itself with the lease manager. The ISponsor interface is used by the lifetime service to call back to the sponsor.

public ref class MyClientSponsor: public MarshalByRefObject, public ISponsor
   DateTime lastRenewal;

      lastRenewal = DateTime::Now;

   virtual TimeSpan Renewal( ILease^ /* lease */ )
      Console::WriteLine( "Request to renew the lease time." );
      Console::WriteLine( "Time since last renewal: {0}",
         DateTime::Now - lastRenewal );

      lastRenewal = DateTime::Now;
      return TimeSpan::FromSeconds( 20 );
