Question

I have the following code in C#

if ((l = d.Length) > 0)
{
    for (i = 0; i < l; i++)
    {
        Console.WriteLine(d[i]["id"]);
    }
}

and it puts a little red highlight under l and i and when I hover the mouse over it, it says

The name i does not exist in the current context.

Why is that?

Answer 1

you haven’t declared i properly it should be int i

if ((l = d.Length) > 0)
        {
            for (int i = 0; i < l; i++)
            {
                Console.WriteLine(d[i]["id"]);
            }
        }
