1、成功信息网这里是我的毕业设计，用c#编写学校图书馆管理系统。全部仿真测试过，毕业论文获得优秀，分享给大家。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() InitializeCom

2、ponent(); 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

3、= DBHelp.OleReader(sql); dr.Read(); if (dr.HasRows) uacc = this.useracctxt.Text; upsw = this.pswtxt.Text; uname = druname.ToString(); usex = drusex.ToString(); upart = drupart.ToString(); uright = druright.ToString(); MainForm af = new MainForm(this); this.Hide(); this.useracctxt.Clear(); this.pswtx

4、t.Clear(); af.Show(); else MessageBox.Show(账号或密码错误！, 提示！); this.useracctxt.Clear(); this.pswtxt.Clear(); this.useracctxt.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 sende

5、r, 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。3.权限设置主要代码：public partial class RightSet : Form public RightSet() InitializeComponent(); private void RightSet_Load(object sender, EventArgs e) this.rightbox.SelectedIndex = 0; /this.treeright.ExpandAll(); Fill(); private

6、void okbtn_Click(object sender, EventArgs e) if (this.txtnum.Text = string.Empty) MessageBox.Show(请输入最大借阅图书数量！, 提示！); return; if (this.txtday.Text = string.Empty) MessageBox.Show(请输入最大借阅图书时间！, 提示！); return; if (this.txtcost.Text = string.Empty) MessageBox.Show(请输入借书押金金额！, 提示！); return; if (this.txtf

7、ine.Text = string.Empty) MessageBox.Show(请输入超期罚款金额！, 提示！); return; if (this.txttim.Text = string.Empty) MessageBox.Show(请输入图书遗失罚款倍数！, 提示！); return; ArrayList arr = new ArrayList(); foreach (TreeNode nodes in this.treeright.Nodes) if (nodes.Checked) arr.Add(1); else arr.Add(0); foreach(TreeNode node

8、in nodes.Nodes) if (node.Checked) arr.Add(1); else arr.Add(0); string a=new string11; for (int i = 0; i arr.Count; i+) if (arri.ToString().Trim() = 1) ai = yes; else ai = no; string sql = string.Empty; sql += select * from tb_right where uright= + this.rightbox.Text + ; DataTable dt = DBHelp.ExeOleC

9、ommand(sql); bool b = false; while (dt.Rows.Count != 0) b = true; break; string sql1; if (b) sql1 = update tb_right set ; sql1 += maxbook= + this.txtnum.Text + ,; sql1 += maxdate= + this.txtday.Text + ,; sql1 += rcost= + this.txtcost.Text + ,; sql1 += rfine= + this.txtfine.Text + ,; sql1 += rtim= +

10、this.txttim.Text + ,; sql1 += rbm= + a0 + ,; sql1 += rum= + a1 + ,; sql1 += rrm= + a2 + ,; sql1 += rborm= + a3 + ,; sql1 += ris= + a4 + ,; sql1 += rbis= + a5 + ,; sql1 += ruis= + a6 + ,; sql1 += rboris= + a7 + ,; sql1 += rblp= + a8 + ,; sql1 += rbl= + a9 + ,; sql1 += rlp= + a10 + ; sql1 += where uri

11、ght= + this.rightbox.Text + ; else sql1 = insert into tb_right(uright,maxbook,maxdate,rcost,rfine,rtim,rbm,rum,rrm,rborm,ris,rbis,ruis,rboris,rblp,rbl,rlp); sql1 += values( + this.rightbox.Text + , + this.txtnum.Text + , + this.txtday.Text + , + this.txtcost.Text + , + this.txtfine.Text + , + this.t

12、xttim.Text + , + a0 + , + a1 + , + a2 + , + a3 + , + a4 + , + a5 + , + a6 + , + a7 + , + a8 + , + a9 + , + a10 + ); DataTable dt1 = DBHelp.ExeOleCommand(sql1); Fill(); private void Fill() string sql; sql = select rid as ID号,uright as 用户身份, maxbook as 最大借书数量,maxdate as 最大借阅时间,rcost as 押金,rfine as 超期罚

14、ridViewCellEventArgs e) this.rightbox.Text = this.dataGridView11, this.dataGridView1.CurrentCell.RowIndex.Value.ToString().Trim(); this.txtnum.Text = this.dataGridView12, this.dataGridView1.CurrentCell.RowIndex.Value.ToString().Trim(); this.txtday.Text = this.dataGridView13, this.dataGridView1.Curre

15、ntCell.RowIndex.Value.ToString().Trim(); this.txtcost.Text = this.dataGridView14, this.dataGridView1.CurrentCell.RowIndex.Value.ToString().Trim(); this.txtfine.Text = this.dataGridView15, this.dataGridView1.CurrentCell.RowIndex.Value.ToString().Trim(); this.txttim.Text = this.dataGridView16, this.da

16、taGridView1.CurrentCell.RowIndex.Value.ToString().Trim(); ArrayList list = new ArrayList(); string sql = select * from tb_right where uright= + this.rightbox.Text + ; DataTable dt = DBHelp.ExeOleCommand(sql); if (dt.Rows.Count != 0) for (int i = 0; i 11; i+) list.Add(dt.Rows07+i.ToString(); ArrayLis

17、t arr = new ArrayList(); foreach (TreeNode nodes in this.treeright.Nodes) arr.Add(nodes); foreach(TreeNode node in nodes.Nodes) arr.Add(node); for (int i = 0; i list.Count; i+) if (listi.ToString() = yes) (TreeNode)arri).Checked = true; else (TreeNode)arri).Checked = false; 4.权限修改主要代码：public partial

18、 class UserRight : Form public UserRight() InitializeComponent(); private void btncancel_Click(object sender, EventArgs e) this.Close(); private void UserRight_Load(object sender, EventArgs e) this.checkbox.SelectedIndex = 0; this.partbox.SelectedIndex = 0; private void Fill() if (this.checkbox.Text

19、 = ) MessageBox.Show(请选择要使用的查询字段！, 提示！); return; if (this.partbox.Text = ) MessageBox.Show(请选择用户所在的部门！, 提示！); return; string sql = string.Empty; sql += select uid as ID号,uacc as 帐号,uname as 姓名,usex as 性别,upart as 部门,utelphone as 移动电话,uphone as 固定电话,udate as 注册日期,uright as 权限 from tb_user; if (this.c

20、hecktxt.Text != ) string c = this.checkbox.SelectedIndex.ToString(); switch (c) case 0:/用户帐号 if (this.checktxt.Text != string.Empty) sql += where uacc like % + this.checktxt.Text + %; break; case 1:/用户姓名 if (this.checktxt.Text != string.Empty) sql += where uname like % + this.checktxt.Text + %; brea

21、k; default: break; if (this.partbox.SelectedIndex.ToString() != 0) sql += and upart= + this.partbox.Text + ; else if (this.partbox.SelectedIndex.ToString() != 0) sql += where upart= + this.partbox.Text + ; sql += order by uacc asc; DataTable dt = DBHelp.ExeOleCommand(sql); this.dataGridView1.DataSou
