How to get the array cell position when using foreach across an array?

Question

I'm still stuck with using arrays in XSD generated classes, as my XML schema is too complex for xsd2code, which created generics-based generated classes.

Is their any way to tell the cell number of an array when using foreach across it? Is there any way to do so in LINQ?

Answer 1

I assume that by "cell number" you mean the index of the current item in the array.

If so, the answer is yes.

For a for loop, you can declare an integer variable and increment it in each iteration to track the index.

For example:

int index = 0;
foreach(var thing in things) {
    //...

    index++;
}

In LINQ, you can call the overloads of Select and Where that take 2-parameter lambdas, like this:

array.Select((elem, index) => whatever);

Answer 2

You can certainly do it in LINQ:

foreach (var item in Items.Select((elem, index) => new { Item = elem, Index = index }))
{
    DoStuff(item.Item, item.Index);
}
