圖書管理系統

特地給家裏的老弟準備了這樣的小項目，用來練手仍是不錯的，分享你們看一下，仍是一些新穎點的   ！哈哈

就是自定義DataGridView，方便每一個功能部分調用！簡單！再次重申！！！後面源碼會送上！

首先看一下登陸，上圖吧！

只有超級管理員跟管理員

接下來看一下主界面

更改DataGridView數據列

挺簡單的  一下是圖書管理加載的數據方法

            //須要綁定數據庫列名稱的字符串
            string arraysName = @"BookId,BookName,TimeIn,BookTypeName,Author,PinYinCode,Translator,Language,BookNumber,Price,Layout,Address,ISBS,Versions,BookRemark";


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

            //DataGridView1數據集綁定
            this.dataGridView1.DataSource = bookInfo_bll.selectBookInfo1().Tables[0];

            #endregion

            #region 下拉框綁定

            DataGridViewColumnCollection columns = dataGridView1.Columns;

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

            #endregion

            #region 樹狀圖的綁定

            TreeViewBand();

            #endregion

            #region DgvHostory綁定

            string Header1 = @"圖書編號,圖書名稱,讀者編號,讀者名稱,借出時間,書應歸還時間,實際歸還時間,應付罰金,續借次數,借還描述";
            string PropertyNames1 = @"BookId,BookName,ReaderId,ReaderName,BorrowTime,ReturnTime,FactReturnTime,Fine,RenewCount,BorrowRemark";
            //自動生成columns
