C＃如何从主程序运行链接列表的delete方法？

Question

I have a user-made linked list (no LINQ). I have items in them but I want to delete some.

The delete method of my Linked List:

public void Delete(ListElem elem)
    {
        ListaElem helper = null;
        ListaElem prev = null;
        while (helper != elem)
        {
            prev = helper;
            helper = helper.next;
        }

        prev.next = elem.next;
    }

After this I want to delete a specific element from this List but how do I call it?

Answer 1

Let's say your class is called CustomLinkedList

At some point in your code, you have instantiated the class:

CustomLinkedList myList = new CustomLinkedList();

Next, you've added some elements to it:

ListElem elem1 = new ListElem();
myList.Add(elem1);

In order to delete an element, all you have to do is say:

myList.Delete(elem1);

Now, what if you want to search the object for an element that has a certain field, perhaps a name? You need another method, define it like this:

public ListElem Find(String name){
   // For every item in my list, look for one that has a name that matches.
}

Now you can find a particular item and then delete it.
