unit1.DestinationActivityInstanceID = 
       ... // destination activity instance ID
unit1.SourceActivityInstanceIDs = 
       new string[] { ... }; // array of source activity instance ID
WFPartialRollbackInstruction.PartialRollbackUnit unit2 = 
       new WFPartialRollbackInstruction.PartialRollbackUnit();
unit2.DestinationActivityInstanceID = 
        ... // destination activity instance ID
unit2.SourceActivityInstanceIDs = 
       new string[] { … }; // array of source activity instance ID
WFPartialRollbackInstruction instruction = 
       new WFPartialRollbackInstruction();
instruction.PartialRollbackUnits = 
       new WFPartialRollbackInstruction.PartialRollbackUnit[] 
       {unit1,unit2};

try
