objects

Okay, I have what I think is a simple question.. or just a case of me being a C# beginner.

I have an array of custom objects (clsScriptItem) that I am populating from a database. Once the items are loaded, I want to back them up to "backup" array so I can revert the information back after changing the main array. However, when I use CopyTo to copy the array and then alter the original array, the backup array is also being altered... I though CopyTo merely copied values + structure from one array to another.

    private void backupItems()
    {
        lastSavedItems = new clsScriptItem[items.Length];

        items.CopyTo(lastSavedItems, 0);

        //items[0].nexts[0] is 2
        //lastSavedItems[0].nexts[0] is 2

        items[0].nexts[0] = "-1";

        //items[0].nexts[0] is -1
        //lastSavedItems[0].nexts[0] is also -1


    }

How do I backup this data without having the two arrays be 'linked'??

The following is 2 different definitions of the problem: How can I process 2 arrays so that I can keep the data of duplicate array[key] values. I have arrays A and B. I want to create array C with the children that their id/key values exist in both A and B arrays. Thank you >>> More

I'm going through a Fortran code, and one bit has me a little puzzled. There is a subroutine, say SUBROUTINE SSUB(X,...) REAL*8 X(0:N1,1:N2,0:N3-1),... ...
