Recursive call return a List, return type causing me issues

Question

I have a recursive method that is return me categories, and checking for its sub categories.

So it looks like:

public List GetAllChildCat         


        

Answer 1

I had the same problem before. Here is the way I solved it:

public void GetAllChildCategories(ProductCategory ParentCategory)
{
    ParentCategory.ChildCategories = GetChildCategories(ParentCategory.ID);

    foreach(ProductCategory cat in ParentCategory.ChildCategories)
    {
        GetAllChildCategories(cat);
    }
}
