从Excel读取数据并存入数据库

private   DataTable   LoadExcel(string fileName)
        {
            FileInfo   file   =   new   FileInfo(fileName);
            string dataSource, tableName, connectionString, strCmd = String.Empty;
            dataSource   =   file.Name;
            tableName = GetExcelTableName(dataSource);
            connectionString = string.Format("Provider=Microsoft.Jet.OleDb.4.0;data source={0};Extended Properties='Excel 8.0;HDR=Yes;IMEX=1'", dataSource);
            string[] tabs=tableName.Split(';');

            for (int i = 0; i < tabs.Length; i++)
            {
                strCmd = string.Format("SELECT   *   FROM   [{0}] ", tabs[0] + "A1:J10");//选取指定的行和列 取第一个表
              //  strCmd = string.Format("SELECT   *   FROM   [{0}] ", tabs[0]);//取数组中的第一个表名
            }
            OleDbDataAdapter da = new OleDbDataAdapter(strCmd, connectionString);
               dte   =   new   DataTable();
                try
                {
                    da.Fill(dte);
                }
                catch   (Exception   err)
                {
                    throw   new   ApplicationException( "加载数据失败： "   +   err.Message,   err);
                }
                da.Dispose();
            return   dte;
        }

把得到的datatable加入数据库中就可以了
