Property to retreive value from the ArrayList object which supports the .NET frame work

hi,
I thought i can use Item[] property to retrieve the value of array list at a particular index. In my case, I have created an object to ArrayList class and added some values to it. What i want is to retrieve the values randomly. The only problem is, I am unable to use the Item[] property as i am working with my project on .NET frame work. Please help me and solve the problem very soon.
