Complex Data Structures

misterqj · March 18th, 2005, 05:17 PM

I have been programming perl for a few years, and am used to being able to build and access complex data structures like hashes of hashes, arrays of hashes, hashes of arrays, etc.

I am trying to do the same in VB.NET, and eventually in C#, but I am finding very little on how to do this. Building these structures seems to be easy. For example

Code:

myHash.Add("key", myArray) 'myArray is an arraylist of strings

to make a hashtable entry that is an array.

I just can't seem to figure out how to get at the array once it is in the hash. Any direction/documentation would be greatly appreciated.

Thanks.

Never mind,

I was able to use the debugger to see how the array is being stored, and then use that info to figure out how to reference it.

you give the key and hashtable gives the entry(according to the GetHashCode which is implemented in the keys,in your case String.GetHashCode)

Code:

//C#
ArrayList ar=(ArrayList)myHash["key"];
