C# 读取Excel并解析

        public static DataTable GetExcelToDataTableBySheet(string FileFullPath, string SheetName="")
        {
            //SheetName = "Sheet1$";
            //HDR=Yes, 表示第一行为列名第二行才是数据 / HDR=No, 第一行就是数据;      
            string strConn = "Provider=Microsoft.Ace.OleDb.12.0;" + "data source=" + FileFullPath + ";Extended Properties=‘Excel 12.0; HDR=YES; IMEX=1‘"; 
            using (OleDbConnection conn = new OleDbConnection(strConn))
            {
                DataSet ds = new DataSet();
                //如果想要按列过滤的话 eg: "SELECT * FROM [{0}] where [列名] is not null", 和sql有点类似
                OleDbDataAdapter odda = new OleDbDataAdapter(string.Format("SELECT * FROM [{0}] where [设备编号] is not null", SheetName), conn); 
                odda.Fill(ds, SheetName);

                return ds.Tables[0];
            }
        }
