Reflection can also be so?

Today saw a blog mentioned the use of reflection, did not think you can use this: you can use after reflection by putting a prefix "*" Find members include prefixes:

 1 MemberInfo[] members  =   typeof (A).GetMember( " hidden* " , 
 2     BindingFlags.NonPublic  |  BindingFlags.Instance);
 3
 4 //  members now contains three members: hiddenFlag1, hiddenFlag2 and hiddenMethod
 5
 6 //  
 7
 8 public   class  A
 9 {
10    private bool hiddenFlag1;
11    private bool hiddenFlag2;
12
13    private void hiddenMethod()
14    {
15    }
16
17    private void reallyHiddenMethod()
18    {
19    }
20}
