How to retrieve a single ‘Default Value’ for a parameter in a Crystal report using Crystal Reports .NET SDK?

• Visual Studio 2008 / Visual Studio 2010
• Crystal Reports 2008 / Crystal Reports for Visual Studio 2010

• Currently, there is an API available in Crystal Report for Visual Studio 2010 Service Pack 3 .NET SDK to access the single value which is set as a ‘Default value’ in parameter properties.
• Refer to below snapshot. 

• Code to get the Default Value:

  private void getDiscreteValues(CrystalDecisions.ReportAppServer.DataDefModel.ISCRParameterField paramfield)
  {
      string textBox1 = String.Empty;
      string name = paramfield.Name;
      int currValCount = paramfield.InitialValues.Count;
      int defValCount = paramfield.DefaultValues.Count;

      if (defValCount > 0) //this parameter has default values
      {
          foreach (ParameterFieldDiscreteValue discreteDefaultVal in paramfield.DefaultValues)
          {
              MessageBox.Show("Discrete default value1 " + discreteDefaultVal.Value.ToString());
              if (discreteDefaultVal.Description != null)
              {
                  discreteDefaultVal.Description.ToString();
                      MessageBox.Show("Discrete description value " + discreteDefaultVal.Description.ToString());
              }

             // This is the new API to get the Default value
              foreach (ParameterFieldDiscreteValue CurrentInitialVal in paramfield.InitialValues)
              { // Always only going to be 1
                  MessageBox.Show("Default Value: " + CurrentInitialVal.Value.ToString());
              }

          }
      }
      Else
