asp.net下将Excel转成XML档的实现代码

if (this.FileUpload1.PostedFile != null) 
{ 
string filename = this.FileUpload1.FileName.ToString(); 
string path = @Server.MapPath("../File/") + filename; 
this.FileUpload1.PostedFile.SaveAs(path); 
//读取用户上传的Excle文件 
string conn="Provider = Microsoft.Jet.OLEDB.4.0 ;Data Source ='"+path+"';Extended Properties=Excel 8.0"; 
OleDbConnection olecon = new OleDbConnection(conn); 
olecon.Open(); 
//注意表名,打开Excel文件后,最底部分页的Excle名字, 
//默认是$Sheet1,$Sheet2,$Sheet3 
string sql = "select * from [$Sheet1]"; 
OleDbDataAdapter oleda = new OleDbDataAdapter(sql,conn); 
oleda.Fill(ds); 
olecon.Close(); 

this.GridView1.DataSource = ds; 
this.GridView1.DataBind(); 

string file_name = "20091126002.xml"; 
string xml_path = @Server.MapPath("../Reports/xml/") + file_name; 

ds.WriteXml(xml_path); 
ds.Dispose(); 
}
