Trying to understand Collections

[Poppa Mintin]

Hi Guys,

After being admonished yet again by jmcilhinney I'm trying to understand Collections.

I can use the code: -

 Dim Col1 As New Microsoft.VisualBasic.Collection()

without much of a problem.

But now I'm trying to use 'Pairs' of data. Collection as above will accept a pair of data, but I can't find how to retrieve both.

So I looked at: -

Dim Col2 As New Hashtable()

Which it seems is more designed towards 'Pairs', but again, I can submit a pair of data and they're accepted, but again I can't find how to retrieve 'em.

Setting a breakpoint after adding a pair of data to either type of collection I can see in the 'Locals' window that both data are there, in my case they're listed as 'Key' and 'Value' although the 'key' is an integer and the 'Value' is a string... They're listed as such, so something must be right.

So I'm asking how to retrieve both data, I can only retrieve the 'Key' at the moment.

With a string data and an integer data in Col1 and using : -

Dat1 = Col1.Item(1)

For example will put the 'String' into the string variable Dat1.
I tried: -

Dat2 = Col.Item(1)

But that failed at runtime... Dat2 as an Int32 was the wrong variable type. I thought maybe it was cleaver and know which data type I was asking for, I did wonder what would happen in that case if both data types were the same.

I tried the same with Col2 with the same result.

Poppa.
