C图书管理系统源代码 Standardization of sany group #QS8QHH-HHGX8Q8-GNHHJ8-HHMHGN#图书管理系统系统功能：1．借书：根据借书人提出的图书编号（id）查询该图书，如果该图书现存量（store）不为0，则提示输入借阅者的学号（num），为借书人办理借书手续，提示用户该书已被借出。
2．归书：根据借书人的学号查询该读者的信息，若有该读者，则提示输入所借书籍的编号（id）,为该读者办理还书手续，提示该书已还。
3.书籍管理：弹出书籍管理界面，输入所要执行操作的号码：（1）增加书籍：弹出注册新书的窗口，按照提示输入所增加书籍的信息，最后，提示用户该书已被注册。
（2）删除书籍：弹出删除书籍的窗口，输入所要删除书籍的编号（id），输出该书的信息，确认是否删除该书，1为删除，0为放弃。
（3）修改书籍：弹出修改书籍的窗口，输入所要修改书籍的编号（id），输出该书的信息，确认是否修改该书，1为修改，0为放弃。
之后按照提示重新输入书籍的信息。
4.读者管理：弹出读者管理界面，输入所要执行操作的号码：（1）增加读者：弹出注册读者的窗口，按照提示输入所增加读者的信息，最后，提示用户该读者已被注册。
（2）删除书籍：弹出删除读者的窗口，输入所要删除读者的学号（num），输出该读者的信息，确认是否删除该读者，1为删除，0为放弃。
（3）修改书籍：弹出修改读者的窗口，输入所要修改读者的学号（num），输出该读者的信息，确认是否修改该读者，1为修改，0为放弃。
之后按照提示重新输入读者的信息。
5.搜索：此搜索包括两方面的搜索，书籍搜索以及读者搜索，弹出搜索的窗口，按照提示输入所要搜索的内容，1为书籍搜索，2为读者搜索：（1）搜索书籍：弹出搜索书籍的窗口，按照提示输入所要搜索的方式，包括按<1>书名搜索，<2>书号搜索，<3>作者搜索，<4>出版社搜索，<5>出版时间搜索;根据所选方式输入相应的内容，若是该书籍存在，则输出该书籍的信息，否则，返回主界面。

c_图书管理系统源代码
学计算机的学兄弟姐妹们，下面是我今年的课程设计，做的一个图书馆的管理系统，用c＃做的,visual studio2008编写的。
代码经测试全部实现，暂时未发现什么bug,在年纪的评比中得到了第一名的成绩.下面把这些代码分享给你们,希望能对你们有所帮助.1。
登陆界面主要代码：public partial class LoginForm : Form{public static string uacc;public static string upsw;public static string uname;public static string usex；public static string upart；public static string uright；public LoginForm(）{InitializeComponent（)；}private void loginbtn_Click（object sender，EventArgs e){if (this。
useracctxt。
Text。
Trim() == "”＆＆this.pswtxt.Text == ””){MessageBox。
Show("请输入您的用户名和密码！"，”提示！")；return;}try{string sql；sql = ”select ＊ from tb_user where uacc='" + this。
useracctxt.Text + "’ and upsw='" + this。
pswtxt.Text + "’"；OleDbDataReader dr = DBHelp.OleReader(sql)；dr.Read（）；if（dr。
HasRows）｛uacc = this。
useracctxt。
Text；upsw = this.pswtxt.Text;uname = dr［"uname”］.ToString（);usex = dr["usex"].ToString（)；upart = dr[”upart"］。
