先入正題吧！
1：創(chuàng)建wpf應(yīng)用。我用的VS是2013！
2：創(chuàng)建wpf文件并且起名字！
3：起一條虛線
3：打開我們電腦基本的計算器，然后我們模仿他來做計算器吧！
4：在工具箱找到lable，把他拖進來。并且起一個名字！設(shè)置他的屬性。
4：再然后在工具箱找到button按鈕把他拖進來。并且?guī)退鹈?，還有設(shè)置他的屬性！
5：寫完整的界面，按鈕直接復(fù)制粘貼就可以的！下一步進行后臺代碼！
6：定義三個變量存放數(shù)據(jù)！
7：設(shè)置按鈕0的點擊事件！然后數(shù)字鍵復(fù)制粘貼就可以了！
8：設(shè)置符號鍵，給他賦值！
9：設(shè)置C按鍵清除所有！這個問了很多人才找到的C按鍵清除lable！
10：設(shè)置等于號按鍵促發(fā)加減乘除！
11：然后一個計算器完成了！下面是全部代碼！

根據(jù)大家的需求。以前寫的計算器是不可以連續(xù)計算的?，F(xiàn)在已經(jīng)更改可以連續(xù)計算了。只是添加了幾個判斷。很簡單的。
這個是代碼，有注釋哦。
第一：在計算器的數(shù)字進行判斷。
第二：在等號的方法進行判斷。超級簡單易懂。
有需要源碼的也可以聯(lián)系我。有一次滿足的大眾的需求。哈哈哈哈哈~~~~
這個是項目的源碼下載地：
如果有不足的地方歡迎多多指教！記得我是一個熱愛編程的男孩子！有錯誤的地方多多指點！我是一個剛剛畢業(yè)入門的應(yīng)屆生！希望我們一起進步！有問題可以咨詢我！歡迎給我留言！
