If I send a dataset to a dataadapter to update a database...

char myChar = something;
 
      switch(myChar)       
      {         
         case (char)88:   
            // code
            break;                  
 
         case (char)98:            
            // code
            break;
 
         case (char)100:
         case (char)101:
         case (char)102:
            // code
            break;
 
         default:            
            // code
            break;      
      }

void UCOMIPersistFile.GetClassID(out Guid pClassID)
{
  /// ...
}

((UCOMIPersistFile)this).GetClassID(out someGuid);
