c# 客户端 上传excel数据到sql，弄了一晚都弄不好
 
  现在是 需要把一些xls文件上传到数据库并新建新表，表的列名结构不一样。该怎么做？我在网上搜了一晚，看到opendatasourse的方法挺好用的，可是网上都是直接在sqlserver操作的。
下面这个代码能实现吗？

C# code

BaseClass.SqlClass sqlclass = new HRP.BaseClass.SqlClass();
                         SqlConnection con = sqlclass.SqlConBind();
                         con.Open();
                         SqlCommand scd = new SqlCommand("SELECT   * INTO NEWTABLE OPENROWSET('MICROSOFT.JET.OLEDB.4.0','Excel 8.0;HDR=YES;DATABASE=c:\a.xls',sheet1$)", con);
                         scd.CommandTimeout = 20;
                         scd.ExecuteNonQuery();
                         con.Close();

报错信息：未处理的“System.Data.SqlClient.SqlException”类型的异常出现在 System.Data.dll 中。其他信息: 关键字 'OPENROWSET' 附近有语法错误。
  刚开始摸索编程觉得它很难哦，遇到问题的时候很多时候找不到方向。有些气馁。熬夜好伤哦，为什么男孩子那么喜欢熬夜？不是很熟悉csdn的操作，如果哪里不对，请帮我指出。
