Iterate the list for the first half of the position

I try to iterate over the list only for the first half of the elements, and then again I want to iterate over the list only for the remaining half of the list. Any ideas?

@foreach (var category in Model.Categories.OrderBy(i => i.CategoryName))
{
  <li>
    <div id="category_@(category.SKU)" 
         class="itemBlock" 
         onclick="toggle('@(category.SKU)')">
  </li>
}

Sort of:

var categories = Model.Categories.OrderBy(i => i.CategoryName).ToList();
int noOfCategories = categories.Count();
int half = noOfCategories/2;

for (int x = 0; x < half; x++)
{
    var category = categories[x];
    //your logic here
}
for (int x = half; x < noOfCategories; x++)
{
    var category = categories[x];
    //your logic here
}

Must do the trick, can not guarantee that the syntax is 100%, but this should give you everything you need to do!

Just use for a loop .

for(int i=0; i < Model.Categories.OrderBy(i => i.CategoryName).Count/2; i++)
{
    // do stuff
}

for(int i=Model.Categories.OrderBy(i => i.CategoryName).Count/2; i < Model.Categories.OrderBy(i => i.CategoryName).Count; i++)
{
    // do different stuff
}

    public List<Category> CategoriesUpperHalf
    {
        get { Categories.OrderBy(i => i.CategoryName).GetRange(_mid, _top); }
