C# Arrays - Conversion/Copy

Question

I need an array of the same dimensions (to hold values 0 or 1) as an argument to a function which may be of any rank and any type. The result array will contain 0 for failure and 1 for success (I could use Boolean) arising from a process. How can I create the result array?

What is the specific requirement? Did you try anything? Creating a boolean array of a specific size maybe? — Arghya C

This seems like an insane requirement. For failure, you should throw an exception. — Ian Newson

@IanNewson: It's not insane. There are times when you have a list of things you want to do, and you want to report which of them could be done. Exceptions are often the best solution for failure situations, but not always. — StriplingWarrior

Use Array.CreateInstance:

private static Array CreateArray(Array array)
{
    List<int> dimensions = new List<int>();
    for (int i = 0; i < array.Rank; i++)
    {
        dimensions.Add(array.GetLength(i));
    }
    return Array.CreateInstance(typeof(bool), dimensions.ToArray());
}
