Sharing the small programs for restaurants and game equipment produced by. net

This article mainly introduces. net makes small programs for restaurants and game equipment, and friends will no longer have to consider where to eat every day. it is very fun and practical, for more information, see this article. net makes small programs for restaurants and game equipment. friends no longer need to consider where to eat every day. it is very fun and practical. if you need it, please refer to it.

Create an asp.net web project and drag it in. Now I know why the game is always vulnerable because its weight is very small... Eat at random at noon. if you want to go to any one, set the weight value to a greater value. if you can't get it, just quit!
