Efficiently Getting Indices in C# Iterations
The foreach loop in C# is a convenient way to iterate over collections, but it doesn’t inherently provide the index of the current iteration. This can be inconvenient when you need both the element and its index. This article explores two effective methods to retrieve the index within a foreach-like…
