Cannot retrieve records from Hash table

[cmrhema]

Hi
I have added datas into a hash table as below

 For I = 0 To RowCount - 1
                                        
RegNo = (Ds.Tables("chktable").Rows(I)(0))
                    
                    
dataTime = (Ds.Tables("chktable").Rows(I)(1))
                                      
ht.Add(Ds.Tables("chktable").Rows(I)(0), Ds.Tables("chktable").Rows(I)(2))Id = (Ds.Tables("chktable").Rows(I)(2))

'I have added only two fields the first and the last one
Next

Now my problem is i cannot retrieve anything
when i put the code as
If ht.ContainsKey( "dfd")Then
Console.WriteLi ne("found")
End If

i do not get either reply or error

Help me out
