Increment i inside for loop of foreach loop

Question

I need to produce an output as below. For each item in @ViewBag.Table, duplicate 3 times and then increment the value i by 1 for each foreach iteration

eg: Values return by @ViewBag.Table { "Test", "AA", "Hello" }
Output:

Test   1
Test   2
Test   3
AA     4
AA     5
AA     6
Hello  7
Hello  8
Hello  9

How could this be done?

@foreach(var item in @ViewBag.Table)
{
  for (int j = 1; j <= 3; j++)
  {       
    @item.Column1 + " " + i;
  }
}

@FarhadJabiyev changing the i to j will keep repeat the value 1, 2, 3. I need the next one to be 4, 5, 6, etc. What the expectation is increment the i as shown in the sample above. And i can't declare variable i outside of the foreach loop. — vincentsty

You can increment i the same way as you already showing for j... Not sure what stops you from doing that... — Alexei Levenkov

Why can't you declare i outside the loops? If not, where did you declare it? — Sam Axe

Oh, missed the bit about not declaring i outside the loop. Although that just sounds wrong anyway. — Ceisc

You can increment i anywhere inside the foreach loop, you can even do it on the same line where you assign it's value:

@{int i = 1;}
@foreach(var item in @ViewBag.Table)
{
  for (int j = 1; j <= 3; j++)
  {       
    @item.Column1 + " " + i++;
  }
}

PS. As Ceisc mentioned, a standard way to start begin the loop is to start it from 0.

Given that the value of j isn't used, I'd probably have gone with for (int j = 0; j < 3; j++) as I prefer to have everything start at zero.

@Ceisc that's how the OP does it, so I've decided to leave it like this.

Ceisc Over a year ago

Yeah, I appreciate that is how the OP had it. My comment was more to suggest to them that it's more standard to do zero-based rather than a complaint that your answer didn't.

Vsevolod Goloviznin Over a year ago

@Ceisc yeah, that's true, I will include the comment about it :)

Correct answer but it's woth noting that, in general, a View shouldn't be doing so much.
