convert from foreach to for loop

Question

below code working perfectly . but i need to convert it from foreach to for loop .please help me to iteration by for loop. because i have to introduce some if else statement in entire code

@foreach (var item in ViewData["productSl_1"] as IEnumerable<Nazmulkp.Models.Product>)
{      
    <div class="col-md-3 ">
      <div class="thumbnail">
          <a href="#" class=""><img src="@Url.Content(item.ImagePath)" alt="Image" style="max-width:100%;"></a>
          <div class="caption">  
             <h5>@item.ProductName</h5>
             <h4>Tk.@item.Price</h4>
          </div>
        </div>
    </div>
}

Example:

I have to make sure if index number 2 than execute <div class="col-md-3>"

Thank you

You do not need to convert your foreach to a for loop for adding a conditional css class. Simply add a counter variable to your code and use that for your if condition as needed.

For example, the below code will add the css class "col-md3" to the 3rd item in your collection.

@{ var counter = 0;}
@foreach (var item in YouCollectionHere)
{
    <div class="@(counter==2?"col-md-3":"")">
        <h2>@item.Name</h2>
    </div>
    counter++;
}
