基於C#的商店銷售管理系統的設計與實現
阿新 • • 發佈：2019-01-17
一、實驗設計思路
用Winform的方式實現，充分利用C#的面向物件特性，模擬了十種商品的進貨、購買與銷售過程，每種商品都有其特定的編號，名稱，價格，庫存（用類product實現）。登入設定分兩種，一種是管理員登入（賬號：lczq，密碼：lz19951002），第二種是使用者登入（賬號：customer，密碼：customer）。
二、實驗設計分析
（1）建立 product 類
class product { //商品編號 int id; public int Id { get { return id; } set { if (value != 0) id = value; } } //商品名字 string name; public string Name { get { return name; } set { if (value != "") name = value; } } //商品價格 double price; public double Price { get { return price; } set { if (value >= 0) price = value; } } //商品數量 int amount; public int Amount { get { return amount; } set { if (value >= 0) amount = value; } } public product() { } public product(int Id, string Name, double Price, int Amount) { id = Id; name = Name; price = Price; amount = Amount; } public double sum_price(int number) { return (double)number * price; } }
（2） 然後分別對管理員和使用者進行視窗設計，button，textBox會比較多，這裡的設計具體看程式碼，標有註釋。
三、程式流程

四、實驗總結
寫了一天多了，實驗自己測了一下，bug還是蠻多的，從中總結出了自己寫窗體應用程式時思路不是很清晰，想象力不夠啊，程式碼寫得也很冗雜，有待提高。

昨天倆老師突然闖進1106，說以後不能在實驗室過夜，我想肯定是院長的發的牢騷 。。。
今天在ACM實驗室待著待著，突然又闖進來幾個老師，說ACM實驗室以後也成為公共實驗室 ，說我們不能自己帶鑰匙了，說每天早上八點可以找老師開門，晚上九點四十必須清場，說ACM實驗室會裝上攝像頭監控，說…………
呵、呵、呵、、、、、、
不知道他們在想什麼。。。
神煩。越來越覺得華師計算機學院的某些老師，領導就是巨坑，某些管理制度更是令人難以接受。
明天呢，是不是要四個老師繼續突然闖進來，然後xxxxoooo一大片讓人聽到耳朵就不清淨的話。
唉唉，算了，不吐槽了，，做好自己的事就好。
