A while ago, I wanted to use C # To write a mine clearance program to test how C # worked for more than a year. The basic implementation of mine clearance is very simple. It dynamically generates controls and then uses controls. add to the window,

Except list the collection class does not have a similar version of a non-generic set. The linked list is a two-way linked list. Its elements point to the elements before and after it. The advantage of the linked list is that if you insert an
