导入Excel到数据库

DataTable dt = new DataTable();//全局

//第一步：首先上传到服务器
        string strFileNewName =DateTime.Now.ToString("yyyyMMddhhmmss") + ".xlsx";
        FileUpload1.SaveAs(Server.MapPath("../Excel/Upload/" + strFileNewName));

 //第二步：将Excel的内容导入到DataTable中       
        using (OleDbConnection conn = new OleDbConnection("Provider = Microsoft.Ace.OleDb.12.0; Data Source =" + Server.MapPath("../Excel/Upload/" + strFileNewName) + " Extended Properties=Excel 8.0″"))
        {
            string filepath = Server.MapPath("../Excel/Upload/" + strFileNewName);
            bind(filepath);         
        }

循环表

  for (int i = 0; i < dt.Rows.Count; i++)
            {对取到的值进行处理｝

 private void bind(string fileName) {
          string strConn = "Provider=Microsoft.Ace.OleDb.12.0;" +
                 "Data Source=" + fileName + ";" + 
                 "Extended Properties=‘Excel 12.0;HDR=Yes;IMEX=1‘";
            OleDbDataAdapter da = new OleDbDataAdapter("SELECT *  FROM [Sheet1$]", strConn); 
            DataSet ds = new DataSet();
            try
            { 
                da.Fill(ds); 
                dt = ds.Tables[0];
            } 
            catch (Exception err)
            { 
               // MessageBox.Show("操作失败！"+err.ToString());
            }
        }
