Page.ClientScript.RegisterStartupScript(this.GetType(), "shifou", " ");
return;
}
string Name = FileUpload1.PostedFile.FileName; //获取初始文件名
int j = Name.LastIndexOf("."); //取得文件名中最后一个"."的索引
string newext1 = Name.Substring(j); //获取文件扩展名
if (newext1 != ".xls" && newext1 != ".xlsx")
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "wenjian", "");
return;//当选择的不是Excel文件时,返回
}
SqlConnection cn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
cn.Open();
//savePath = Path.GetFullPath(FileUpload1.PostedFile.FileName);// FileUpload1.PostedFile.FileName.ToString();
if (FileUpload1.HasFile == false)//HasFile用来检查FileUpload是否有指定文件
{

return;//当无文件时,返回
}

filename = FileUpload1.FileName; //Path.GetFileNameWithoutExtension (FileUpload1.PostedFile.FileName);
savePath = Server.MapPath(("../../UploadFiles/xls/") + filename);
FileUpload1.SaveAs(savePath); //保存XLS文件

DataSet ds = ExecleDs(savePath, filename); //调用自定义方法
DataRow[] dr = ds.Tables[0].Select(); //定义一个DataRow数组
int rowsnum = ds.Tables[0].Rows.Count;
if (rowsnum == 0)
{
//当Excel表为空时,对用户进行提示
Page.ClientScript.RegisterStartupScript(this.GetType(), "kong", "");
}
else
{
for (int i = 0; i < dr.Length; i++)
{

　　　　　　　　//自定义的model-student

OleDbConnection conn = new OleDbConnection(strConn);
OleDbDataAdapter odda = new OleDbDataAdapter("select * from [Sheet18$]", conn);//【sheet18$】是表格名

DataSet ds = new DataSet();
