Transferring data between objects in the Responsibility Chain template

When implementing the Chain of Responsibility template, I came across a dilemma on how to transfer data between objects in the chain. The types of data transferred between an object in a chain may vary for each object. As a temporary fix, I created a Static class containing a stack, where each object in the chain can push the results onto the stack, and the next object in the chain can push the results from the stack. Here is an example of the code that I implemented.

public interface IHandler
{        
  IHandler Successor {get; set; }
  void Process();        
}

//Temporary Data Container class to store objects\data    
public static class StackManager
{
  public static Stack DataStack = new Stack();
}

//This class doesn't require any input to operate
public class OpsA : IHandler
{
  public IHandler Successor {get; set; }
  public void Process()
   {
      //Do some processing, store the result into Stack
      var ProcessedData = DoSomeOperation();
      StackManager.DataStack.Push(ProcessedData);

      if(Successor != null) Successor();            
  }
}

//This class require input data to operate upon
public class OpsB : IHandler
{
  public IHandler Successor {get; set; }
  public void Process()
  {
      //Retrieve the results from the previous Operation
      var InputData =  StackManager.DataStack.Pop();

      //Do some processing, store the result into Stack
      var NewProcessedData = DoMoreProcessing(InputData);      
      StackManager.DataStack.Push(NewProcessedData);

      if(Successor != null) Successor();
  }
}

public class ChainOfResponsibilityPattern
{
  public void Process()
  {
       IHandler ProcessA = new  OpsA();  
       IHandler ProcessB = new  OpsB();

       ProcessA.Successor = ProcessB;
       ProcessA.Process();
  }
}

Please help me find the best approach for transferring data between handlers in the chain.
