Advice on using StackFrame and reflection in BLL to return property values

Just for fun I was playing around with creating an interface to a
permissions object and ended up with this.  Just wondering if C# community
thought this is a good solution or not.  What I ended up doing was instead
of writing a lot of non-generic redundant code peppered with literals to
access some permission settings I used the stack frame to figure out which
defined property was getting called by the client and than querying the
cached dataset for the results.  I fully understand that just because I can
doesn't mean I should but I was impressed by what I could do with C# to cut
down on what could have been a lot of messy and redundant code.  What do you
think?

thanks for your time!

public class Permissions
{
  protected Nimbus.PermissionsDataTable thePerms = null;
  public Permissions( string aUsername )
  {
    thePerms = (new PermissionsTableAdapter()).GetData(aUsername);
  }
  protected bool getPerm()
  {
    System.Diagnostics.StackTrace st = new System.Diagnostics.StackTrace(1);
    System.Diagnostics.StackFrame sf = st.GetFrame(0);
    string perm = sf.GetMethod().Name.Replace("get_","");

    bool rv = false;
    try
    {
       DataRow[] rows = thePerms.Select(
String.Format("Permission='{0}'",perm) );
       // etc...
     }
     catch( Exception  )
     {
     }
     return rv;
  }
  public bool Admin            { get { return getPerm(); } }
  public bool CreateBudget { get { return getPerm(); } }
  public bool EditLineItem   { get { return getPerm(); } }
  // etc...
};
