C#读取Excel中数据，首先上传选择的xls文件,根据得到路径,读取文件信息,插入到数据库中。
using System.Data; using System.Data.OleDb; using System.IO; using System.Text; protected void Page_Load(object sender, EventArgs e) { } public void ExcelToDS(string path) { string strSheetName = "sheet1"; string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +path + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'"; //Sql语句 string strExcel = "select * from [" + strSheetName + "$] "; DataSet ds = new DataSet(); //连接数据源 OleDbConnection conn = new OleDbConnection(strConn); conn.Open(); //适配到数据源 OleDbDataAdapter adapter = new OleDbDataAdapter(strExcel, conn); adapter.Fill(ds, "data"); conn.Close(); GridView1.DataSource = ds.Tables["data"]; GridView1.DataBind(); Label1.Text = ds.Tables[0].Rows.Count.ToString(); SqlAccess.Sqldatabase sql = new SqlAccess.Sqldatabase(); StringBuilder sb = new StringBuilder(); for (int i = 0; i < ds.Tables[0].Rows.Count; i++) { sb.Append("insert into data values('" + ds.Tables[0].Rows[i]["companyname"] + "','" + ds.Tables[0].Rows[i]["telname"] + "','" + ds.Tables[0].Rows[i]["qytel"] + "','" + ds.Tables[0].Rows[i]["fax"] + "');"); } sql.ExecuteNonQuery(CommandType.Text, sb.ToString()); } protected void Button1_Click(object sender, EventArgs e) { string fileName = null; try { Boolean fileOK = false; String path = Server.MapPath("./doc/"); if (FileUpload2.HasFile) { String fileExtension = System.IO.Path.GetExtension(FileUpload2.FileName).ToLower(); String[] allowedExtensions = { ".xls" }; //C#读取Excel中数据 for (int i = 0; i < allowedExtensions.Length; i++) { if (fileExtension == allowedExtensions[i]) { fileOK = true; } } } if (fileOK) { fileName = "r_" + DateTime.Now.ToString("yyyy_MM_dd_hh_mm_ss") + "_" + DateTime.Now.Millisecond + System.IO.Path.GetExtension(FileUpload2.FileName).ToLower(); if (File.Exists(path + fileName)) { Random rnd = new Random(10000); fileName = fileName + rnd.Next(); } FileUpload2.PostedFile.SaveAs(path + fileName); } else { } } catch (Exception exp) { } ExcelToDS(Server.MapPath(".") + "\\doc\\"+fileName); }C#读取Excel中数据并插入到数据库中就介绍到这里。
