HashTable error in VB.NET

[MKP]

Hi,

"""" I am getting the error Item has already been added. Key in Dictionary "0". Key being Added "0". """"

From form i have loaded a series of numbers to Class1. In Class1 i am using HashTable to store the values.

Then i am passing the values from Class1 to Class2 for doing some operations. Here also in Class2 i am stroing the values in HashTable.

But getting the above error while debugging.

Please Advice.

Thanx in Advance.

a hashtable can't contain one more equal key

for example you can't add 2 keys saying "keytwo"

So how to get around this problem.

How can i take say 10 numbers out of a series of 100 numbers stored in a Hashtable in Class1 and do some mathematical operation (the operational logic is in Class2).

Or is there any better way of doing it?

i didnt quite get what you meant.
why can't you use a regular array? or a collection?
