C#图书管理系统 附源码下载

用来练手还是不错的，分享大家看一下，还是一些新颖点的！哈哈 

就是自定义DataGridView，方便每个功能部分调用！简单！再次重申！！！后面源码会送上！

首先看一下登录，上图吧！ 

只有超级管理员跟管理员

接下来看一下主界面 

更改DataGridView数据列

datagridView自定义类

GridView.Columns.Add(c);

挺简单的  一下是图书管理加载的数据方法 

private void BookInfoManager_UI_Load(object sender, EventArgs e)
{
#region DataGridView1绑定
//需要添加列的列标题字符串
string arraysHeaderText = @"图书编号,图书名称,登记时间,图书类型,作者,拼音码,翻译,语言,页数,价格,印刷版面,存放位置,ISBS码,版本,描述";
//需要绑定数据库列名称的字符串
string arraysName = @"BookId,BookName,TimeIn,BookTypeName,Author,PinYinCode,Translator,Language,BookNumber,Price,Layout,Address,ISBS,Versions,BookRemark";

//自动生成columns
autocoumns.AutoColumn(arraysHeaderText, arraysName, dataGridView1);
dataGridView1.DataSource = bookInfo_bll.selectBookInfo1().Tables[0];
autocoumns.AddColumn("修改", dataGridView1);
autocoumns.AddColumn("删除", dataGridView1);

//DataGridView1数据集绑定
this.dataGridView1.DataSource = bookInfo_bll.selectBookInfo1().Tables[0];
//窗体加载时默认隐藏的列
this.dataGridView1.Columns[14].Visible = false;
this.dataGridView1.Columns[13].Visible = false;
this.dataGridView1.Columns[12].Visible = false;
this.dataGridView1.Columns[11].Visible = false;
this.dataGridView1.Columns[10].Visible = false;
#endregion

#region 下拉框绑定

DataGridViewColumnCollection columns = dataGridView1.Columns;

for (int i = 0; i < columns.Count - 2; i++)
{
comboBox1.Items.Add(columns[i].HeaderText);
}
comboBox1.Items.Insert(0, "全部");
comboBox1.SelectedIndex = 0;

#endregion

#region 树状图的绑定

TreeViewBand();

#endregion

#region DgvHostory绑定

string Header1 = @"图书编号,图书名称,读者编号,读者名称,借出时间,书应归还时间,实际归还时间,应付罚金,续借次数,借还描述";
string PropertyNames1 = @"BookId,BookName,ReaderId,ReaderName,BorrowTime,ReturnTime,FactReturnTime,Fine,RenewCount,BorrowRemark";
//自动生成columns
autocoumns.AutoColumn(Header1, PropertyNames1, dgvHostory);

#endregion
}
