在项目中经常要用EXCEL导入数据到数据库,提高工作效率。
注意:EXCEL中的第一行不能导入。 下面是源码: IntoExcel.aspx: [csharp] <%@ Page Language="C#" AutoEventWireup="true" CodeFile="IntoExcel.aspx.cs" Inherits="study_IntoExcel" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ".w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns=".w3.org/1999/xhtml" > <head id="Head1" runat="server"> <title>无标题页</title> <script language="javascript" type="text/javascript"><!-- // <!CDATA[ function check() { var k=//S+/.[xls]/; if(!k.test(document.getElementById("fileId")。value)) { alert("只能上次xls格式的文件"); return false; } return true; } // --></script> </head> <body> <form id="form1" runat="server"> <div> <p> <asp:FileUpload ID="fileId" runat="server" /> <asp:Button ID="Button1" runat="server" Text="上传" OnClientClick="return check()" οnclick="Button1_Click" /></p> </div> </form> </body> </html> IntoExcel.aspx.cs [csharp] using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Collections; using System.Configuration; using System.Data; using System.Web.Security; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls.WebParts; using System.IO; using System.Data.OleDb; using System.Data.SqlClient; using System.Web.UI.WebControls; public partial class study_IntoExcel : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } /// <summary> /// 上传文件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button1_Click(object sender, EventArgs e) { string fileName = fileId.FileName; string savePath = Server.MapPath("~/file/"); FileOperatpr(fileName, savePath); fileId.SaveAs(savePath + fileName); DataOperator(fileName, savePath); } /// <summary> /// 数据操作 /// </summary> /// <param name="fileName"></param> /// <param name="savePath"></param> private void DataOperator(string fileName, string savePath) { string myString = "Provider = Microsoft.Jet.OLEDB.4.0 ; Data Source = " + savePath + fileName + ";Extended Properties=Excel 8.0"; OleDbConnection oconn = new OleDbConnection(myString); oconn.Open(); DataSet ds = new DataSet(); OleDbDataAdapter oda = new OleDbDataAdapter("select * from [Sheet1$]", oconn); oda.Fill(ds); oconn.Close(); DataSetOperator(ds,savePath+fileName); } /// <summary> /// 数据集操作 /// </summary> /// <param name="ds"></param> private void DataSetOperator(DataSet ds,string filePath) { SqlConnection conn = new SqlConnection("Data Source=SONYSVR;Initial Catalog=IAR_Factory_811;User ID=sa;Password=P@ssword"); conn.Open(); SqlTransaction str = conn.BeginTransaction();//利用事务处理 防止中断 int k = 0; if (ds.Tables[0].Rows.Count < 1) { Response.Write("<script>alert('没有数据!')</script>"); return; } try { for (int i = 0; i < ds.Tables[0].Rows.Count; i++) { string sqlStr = "insert into IntoExcel(Tname,Tage,Taddress)values"; sqlStr +="('"+ ds.Tables[0].Rows[i][0].ToString()+"',"; sqlStr += ds.Tables[0].Rows[i][1].ToString()+","; sqlStr +="'" +ds.Tables[0].Rows[i][2].ToString()+"')"; SqlCommand cmd = new SqlCommand(sqlStr, conn, str); cmd.Transaction = str; k += cmd.ExecuteNonQuery(); } str.Commit(); } catch (Exception ex) { Response.Write("发生异常,数据已回滚/n信息/n" + ex.Message); str.Rollback(); } finally { Response.Write("上传成功" + k + "条"); File.Delete(filePath); } } /// <summary> /// 文件操作 /// </summary> /// <param name="fileName"></param> /// <param name="savePath"></param> private void FileOperatpr(string fileName, string savePath) { if (!Directory.Exists(savePath)) { Directory.CreateDirectory(savePath); } if (File.Exists(savePath + fileName)) { File.Delete(savePath + fileName); } } } Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + savePath + ";Extended Properties='Excel 8.0;HDR=YES Provider=Microsoft.Jet.OLEDB.4.0;;//连接驱动 Data Source=" + savePath + "; // 数据库地址 Extended Properties='Excel 8.0; // 连接的是Excel8.0 HDR=YES;// 有两个值:YES/ NO, 这2个值,说了你是否能直接读列名,NO,只可以读下标 IMEX=1;//解决数字与字符混合时,识别不正常的情况 这个读入数据库的方式不是最佳的,应该用office组件 select * from [Sheet1$] //引用EXCLE文件中sheet1工作表的内容 OleDB控件用的是OleDb的驱动程序,可以访问各种数据库 数据库中的字段: [sql] create table IntoExcel ( Tid int identity(1,1) primary key, Tname varchar(50), Tage int, Taddress varchar(200), ) SQL控件用的是专用的驱动程序,能高效的访问SQL Server数据库 SQLConnection只能访问SQL Server,而OleDbConnection则可以访问所有数据库。 如果只是访问SQL Server的话,SQL比OleDb更快。 EXCEL数据
