您好我正在使用C＃並嘗試從MainWindow調用Pop（Node類）函數。 pop方法應該返回poped值並將其從堆棧中移除。該函數正在工作，並且從函數內刪除了最高值，但在MainWindow中，堆棧看起來相同（LinkedList不會更改）。這是我的Node類和Pop功能。從堆棧（LinkedList）使用C＃彈出不更新堆棧
public class Node
{
#region Constructor and Declarations
public int custId;
public Node next;
//other fields
public Node(int _data, Node _next)
{
this.custId = _data;
if (_next != null)
this.next = _next;
else
this.next = null;
}
public Node()
{
}
#endregion
//Make Stack
public Node MakeList()
{
Node slist1 = new Node(1, null);
Node slist2 = new Node(2, null);
Node slist3 = new Node(3, null);
Node slist4 = new Node(4, null);
Node slist5 = new Node(5, null);
slist1.next = slist2;
slist2.next = slist3;
slist3.next = slist4;
slist4.next = slist5;
return slist1;
}
#region PopCustomer
public int pop(Node stacktop)
{
Node temp;
int removedCustId = 0;
if (stacktop == null)
return -1;
else
{
temp = stacktop;
removedCustId = temp.custId;
stacktop = temp.next;
temp = null;
}
return removedCustId;
}
#endregion
在mainWindow中，我創建堆棧並調用Pop。 BUT STACK LOOKS SAME - 與CustIDs 1-> 2-> 3-> 4-> 5 NOT 2-> 3-> 4-> 5
//MAIN WINDOW
#region MainWindow
Node stackTop = new Node();
stackTop=stackTop.MakeList();
int popedItem = stackTop.pop(stackTop);//STACK LOOKS SAME - with CustIDs 1->2->3->4->5
#endregion
