How to access index in IEnumerable object in C#?

Question

I have an IEnumerable object. I would like to access based on index for instance:

for(i=0; i<=Model.Products; i++)
{
      ???
}

Is this

Answer 1

There is no index in IEnumerator. Use

foreach(var item in Model.Products)
{
   ...item...
}

you can make your own index if you want:

int i=0;
foreach(var item in Model.Products)
{
    ... item...
    i++;
}
