Enable "Analyze" function for enum members

• 
  Hi Ronald,
  
  Thanks for the suggestion. There is a slight ambiguity which worries me about analyzing a single member - if you have a look at System.Windows.Forms.ComboBox.ComboBoxStyle.GetDropdownStyle(); There is a cast in there from an int to a comboboxstyle - it theory this uses every part of the enum although ComboBoxStyle.DropDown is the only one mentioned explicitly in there - would you expect this to be a use of ComboBoxSyle.Simple?
  
  Thanks,
  
  James

  The intention for the requsted analyse method is to find places where specifically one single member (e.g. ComboBoxStyle.Simple) is used and *not* the other members.
  Places where all enum members could potentially be used are already sufficiently covered through the analyse method on the enum type.
  
  A small test program shows that even source code like

  private static ComboBoxStyle Foo()
  {
      const int value = 1;
      return (ComboBoxStyle)value;
  }
  

  is already disassembled as

  private static ComboBoxStyle Foo()
  {
      return ComboBoxStyle.DropDown;
  }

  The problem is that enum members aren't really used. They're compiled to integers in code. For example, with this enum:
  public enum MyEnum{
  Zero, One, Two
  }
  
  to assign MyEnum.Two to an MyEnum local variable the following IL is generated:
  
  ldc.i4.2
  
  This doesn't give reflector a specific identifier to search for, it would have to search either for all uses of MyEnum then see if 2 is assigned to it, or vice versa. Obviously this would be very slow.
