图书管理系统_(c语言)源代码
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 (eracctxt.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='"+ eracctxt.Text + "' and upsw='" + this.pswtxt.Text + "'";OleDbDataReader dr = DBHelp.OleReader(sql);dr.Read();if (dr.HasRows){uacc = eracctxt.Text;upsw = this.pswtxt.Text;uname = dr["uname"].ToString();usex = dr["usex"].ToString();upart = dr["upart"].ToString();uright = dr["uright"].ToString();MainForm af = new MainForm(this);this.Hide();eracctxt.Clear();this.pswtxt.Clear();af.Show();}else{MessageBox.Show("账号或密码错误！", "提示！");eracctxt.Clear();this.pswtxt.Clear();eracctxt.Focus();}}catch (Exception){MessageBox.Show("数据库无法连接！", "警告！");}}private void cancelbtn_Click(object sender, EventArgs e){Application.Exit();}private void LoginForm_Closing(object sender, FormClosingEventArgs e) {Application.Exit();}}2.主界面（图较小，自己可以拉大点）主要代码就不写了，很简单。

图书管理系统的设计(C语言)
图书管理系统设计图书管理信息包括：图书名称、图书编号、单价、作者、存在状态、借书人姓名、性别、学号等功能描述:1 ．新进熟土基本信息的输入2 ．图书基本信息的查询3 ．对撤销图书信息的删除4 ．为借书人办理注册5 ．办理借书手续6 ．办理换书手续要求：以文件方式存储数据，系统以菜单方式工作。
这是本人大一第二学期初 C 语言课程设计的作品，嘿嘿,本来以为已经找不到原稿了，今天无意中居然在QQ 网络硬盘中找到了当初的teta 版，发布于此，以作记念。
