In .NET, which loop runs faster, 'for' or 'foreach'?

Question

In C#/VB.NET/.NET, which loop runs faster, for or foreach?

Ever since I read that a for loop works faster than a foreach

Answer 1

This should save you:

public IEnumerator For(int start, int end, int step) {
    int n = start;
    while (n <= end) {
        yield n;
        n += step;
    }
}

Use:

foreach (int n in For(1, 200, 4)) {
    Console.WriteLine(n);
}

For greater win, you may take three delegates as parameters.
