Check Registry Entry if it Exists

Anyone know of a better way of testing to see if a reg key exists? Currently I am just catching the nullreferenceexception and using that … but I would prefer a “exists” method or the like …

Anyway, here is what I am doing …

Imports Microsoft.Win32 

Public Class cRegistry 

    Public Shared Function TestForKey(ByVal Reg_Key_Path As String, _ 
                ByVal Reg_Value As String) As Boolean 
        Dim s As String 
        Dim reg_key As RegistryKey 
        Dim reg_hive As RegistryHive 

        Try 

            reg_key = Registry.LocalMachine.OpenSubKey(Reg_Key_Path) 
            If reg_key.ValueCount = 0 Then 
                Return False 
            Else 
                Return True 
            End If 
        Catch nre As NullReferenceException 
            Return False 
        Catch e As Exception 
            Throw New Exception("The following error occured while testing the Registry Key", e) 
        End Try 


    End Function 

End Class
