Question

This is just a simple problem that I’m a little stumped on…

As far as I can see I am not actually using a char anywhere as model.children is a IList<> and model.Name is a string however my foreach loop is giving the error that it can’t convert char to catalogue.department, if you need any more information plese feel free to ask.

        private void DisplayOnWebsiteChecked(Object sender, EventArgs e)
    {
        var departments = model.Name;
        var departmentChildren = model.Children;

        if (departmentChildren != null)
        {
            int zeroChildren = 0;

            if (departmentChildren.Count.Equals(zeroChildren));
            {
                foreach (Department Children in departments)
                {
                }
            }
        }
    }

EDIT: This issue has actually be fixed, I will post the fixed code down below as it turns out I actually messed up the code by putting the list in the wrong place.

    private void DisplayOnWebsiteChecked(Object sender, EventArgs e)
    {
        var departments = model.Name;
        var departmentChildren = model.Children;

        if (departmentChildren != null)
        {
            int zeroChildren = 0;

            if (departmentChildren.Count.Equals(zeroChildren));
            {
                foreach (Department Child in departmentChildren)
                {
                }
            }
        }
    }

Answer 1

model.Name is a string

You have assigned:

var departments = model.Name;

here department is of type string and string implements IEnumerable<char>, that is why when you enumerate over it using foreach, the item in the foreach loop is of type char.

and you are using

foreach (Department Children in departments)
    {
    }

Here Children is of type char since department is a string, whereas you have specified it to be of type Department that is why you are getting this error.
