}

给你一个例子是将现有的excel文件导入的sql2005里面的  代码如下
/// <summary>
    /// 将excel文件导入到dataset中
    /// </summary>
    /// <param name="fileName">文件路径</param>
    private void ImportXlsToData(string fileName)
    {
        string str= "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=\"Excel 12.0;HDR=YES\"";
        string oledbstr = "select * from [Sheet1$]";
        OleDbConnection conn = new OleDbConnection(str);
        try
        {
            conn.Open();
            OleDbCommand com = new OleDbCommand(oledbstr, conn);
            OleDbDataAdapter adp = new OleDbDataAdapter(com);
            DataSet ds = new DataSet();
            adp.Fill(ds);
        }
        catch (Exception err)
        {
            //显示错误信息
        }
        finally
        {
            conn.Close();
        }
    }
接下来你只需要写一个sql把dataset里的数据insert到你的数据库里就可以了

--从sql server中导入/导出 excel 的基本方法
/*===================  导入/导出 excel 的基本方法 ===================*/从excel文件中,导入数据到sql数据库中,非常简单,直接用下面的语句:/*===================================================================*/
--如果接受数据导入的表已存在
insert into 表 select * from
openrowset(microsoft.jet.oledb.4.0
,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)--如果导入数据并生成表
select * into 表 from
openrowset(microsoft.jet.oledb.4.0
,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)
/*===================================================================*/
--如果从sql数据库中,导出数据到excel,如果excel文件已存在,而且已按照要接收的数据创建好表头,就能简单的用:
insert into openrowset(microsoft.jet.oledb.4.0
,excel 5.0;hdr=yes;database=c:test.xls,sheet1$)
select * from 表
--如果excel文件不存在,也能用bcp来导成类excel的文件,注意大小写:
--导出表的情况
exec master..xp_cmdshell bcp 数据库名.dbo.表名 out "c:test.xls" /c -/s"服务器名" /u"用户名" -p"密码"--导出查询的情况
exec master..xp_cmdshell bcp "select au_fname, au_lname from pubs..authors order by au_lname" queryout "c:test.xls" /c -/s"服务器名" /u"用户名" -p"密码"
/*--说明:
c:test.xls  为导入/导出的excel文件名.
sheet1$      为excel文件的工作表名,一般要加上$才能正常使用.
--*/
--上面已说过,用bcp导出的是类excel文件,其实质为文本文件,--要导出真正的excel文件.就用下面的方法
/*--数据导出excel

导出表中的数据到excel,包含字段名,文件为真正的excel文件
,如果文件不存在,将自动创建文件
,如果表不存在,将自动创建表

http://code.google.com/p/excellibrary/

workbook.Worksheets.Add(worksheet);
workbook.Save(file);

// open xls file
