Alternative to foreach in C# Razor page

I need to output complex HTML containing an IEnumerable in a Razor page in an ASP.NET MVC 5 site.

I would like to use nested for loops to structure the HTML - however, this is not possible if all object output is enclosed in a foreach loop.

Rather than use a foreach loop, is there any way to do something like this which would get the next object in the sequence:

if (x = 1)
{
    for (var x=0; x<2; x++)
    {
        <div class="row">
            for (var n=0; n<4; n++)
            {
                <div class="a">
                    Model.GetNextObject.Name
                </div>
            }
        </div>
    }
}
else
{
    <div class="b">
        Model.GetNextObject.Name
    </div>
}

In many situations, this would allow for far more elegant code.

Is this possible?

yes, it is possible,

  1. Get the reference to Enumerator using GetEnumerator
  2. Call movenext method to move to next element

Refer this stack overflow post Using IEnumerable with for loops

var enumerator = getInt().GetEnumerator();
while(enumerator.MoveNext())
{
    var MyObject = enumerator.Current;
    Console.WriteLine(MyObject.Property);
}
