[C#编程] Calculator
设计一个功能完整、界面美观的计算器应用程序。要求：
(1) 用户可通过鼠标点击按钮输入运算数，在文本框中显示，实现加、减、乘、除等四则运算及倒数、取反功能。要求实现良好的布局效果，通过对按钮功能分类简化编程。
（2） 除了鼠标输入外，可同时实现键盘输入和运算(即通过键盘输入数字及运算符时,达到与按钮点击一样的效果)。
（3） 实现小数运算和连续运算；
（4） 实现sqrt，sin等科学计算功能；
（5） 实现表达式解析等附加功能
Design a calculator application program with complete function and beautiful interface. Requirement:
(1) Users can click the mouse button to input the operands and display them in the text box to realize the four operations of addition, subtraction, multiplication and division, as well as the functions of reciprocal and inversion. It is required to achieve good layout effect and simplify the programming by classifying the button functions.
(2) In addition to mouse input, keyboard input and operation can be realized at the same time (that is, when inputting numbers and operators through keyboard, the same effect as button click can be achieved).
(3) Realize decimal operation and continuous operation;
(4) Realize scientific computing functions such as sqrt, sin, etc;
(5) Implement additional functions such as expression parsing (2020-04-17, C#, 2725KB, 下载0次)
[C#编程] 实验1_简单计算器
1、项目概述
该项目目标是设计开发一个支持连续计算的四则运算计算器myCalculator，通过单击按钮，输入并完成如4+5+6或5*8+16类似的连续计算，并将运算结果显示在输出文本框中，同时也具备清空、后退等功能。
2、设计步骤
计算器myCalculator的主要功能是完成加、减、乘、除四则运算，而且支持连续计算，如4+5+7-8或4*5-6等运算。连续计算的实现借助于开发工具中预定义的数据结构Stack（栈）实现，如流程图所示
1. Project overview
The goal of this project is to design and develop a four arithmetic calculator, mycalculator, which supports continuous calculation. By clicking the button, input and complete the continuous calculation such as 4 + 5 + 6 or 5 * 8 + 16, and display the calculation results in the output text box. At the same time, it also has the functions of emptying and retreating.
2. Design steps
The main function of calculator mycalculator is to add, subtract, multiply and divide, and it supports continuous calculation, such as 4 + 5 + 7-8 or 4 * 5-6. The implementation of continuous computing is realized by using the predefined data structure stack (stack) in the development tool, as shown in the flow chart (2020-01-14, C#, 240KB, 下载1次)
[C#编程] 八皇后试验
八皇后问题，是一个古老而著名的问题，是回溯算法的典型案例。该问题是国际西洋棋棋手马克斯·贝瑟尔于1848年提出：在8×8格的国际象棋上摆放八个皇后，使其不能互相攻击，即任意两个皇后都不能处于同一行、同一列或同一斜线上，问有多少种摆法。 高斯认为有76种方案。1854年在柏林的象棋杂志上不同的作者发表了40种不同的解，后来有人用图论的方法解出92种结果。计算机发明后，有多种计算机语言可以解决此问题。

[C#编程] SPL_Robot
SPL_Robot是配合SmartPersistenceLayer使用的一个XML数据库框架的代码生成工具。
SmartPersistenceLayer（SPL）是.NET系统框架持久层。强调是框架带来的灵活性与扩展性。
一、 引用
SPL的发布形式是一个名为PersistenceLayer.Dll的DLL文件,可以在我的BLOG上下载目前最新版：SmartPersistenceLayer3.2，因此只需要在项目中“添加引用”即可：
若要使用ODP.NET连接Oracle数据库，则用以上方式添加Oracle.DataAccess.dll
若要使用SPL连接MySql数据库，则用以上方式添加MySql.Data.dll
二、 配置文件与实体类
SPL的配置文件与实体类可以使用我提供的SmartRobot进行生成（SPL_Robot已经公开源码，请看这里），这可以大大加快开发效率，但工具毕竟是工具，不属于SPL持久层的必选部分。
连接数据库：
目前SmartRobot支持Ms Sql Server、Ms Access、Oracle数据库，如果是其他数据库只能只好手写实体类了或者等我升级喽 )
确定好要生成的实体类存放的地址，到时生成时会生成到相应的目录里。
配置每个表对应的实体类属性，默认实体类名称为“表名”加“Entity”字符，属性名默认与列名相同，上图中的“2”“3”操作对每个表都要
<database name="Northwind" type="MsSqlServer">
<parameter name="Provider" value="SQLOLEDB.1" />
<parameter name="Password" value="tintown" />
<parameter name="Initial Catalog" value="Northwind" />
<parameter name="User ID" value="sa" />
<parameter name="Data Source" value="(local)" />
<classMapFile path="ClassMap.xml" />
</database>
Ms Access例如下：
<database name="DMBCN" type="MsAccess">
<parameter name="Provider" value="Microsoft.Jet.OLEDB.4.0" />
<parameter name="Data Source" value="dmbcn.mdb" />
<classMapFile path="ClassMap.xml" />
