我希望将Execl 表里面的数据导入到数据库

当我代码在本地的时候 导入到sql数据库成功了  可是 当我发布到服务器上面以后 失败了 求高手

我的代码是下面的

        string fileName = FileUpload1.FileName;
        string fPath = Server.MapPath("Upload//") + fileName;//文件保存的路径，服务器上的绝对路径
        string fPaths = Server.MapPath("~/Upload/") + fileName;
      
       
        string type = fileName.Substring(fileName.LastIndexOf(".") + 1);//获取文件后缀名
        //Label1.Text = type;
        if (type != "xls")
            Response.Write("<script language=\"javascript\">alert('只接受上传Excel文件！')</script>");
        else
        {
            string thro = "";
            int drcount = 0;
            int zcount = 0;
            try
            {
            //上传文件
                thro = "保存路径出错";
            FileUpload1.SaveAs(fPath);
            ////////////////将文件内容导入SQL///////////////////////////////////
            //将Excel内容读入数据集中
            string mystring = "Provider = Microsoft.Jet.OLEDB.4.0 ; Data Source = '" + fPath + "';Extended Properties=Excel 8.0";
            OleDbConnection cnnxls = new OleDbConnection(mystring);
            OleDbDataAdapter myDa = new OleDbDataAdapter("select * from [Sheet1$]", cnnxls);
            DataSet myDs = new DataSet();
            myDa.Fill(myDs, "Test");
            GridView1.DataSource = myDs.Tables["Test"];
            GridView1.DataBind();
                //从excel文件获得数据后，插入记录到SQL Server的数据表
                thro = "数据库链接有错";
                SqlConnection sqlCon = new SqlConnection(ConfigurationManager.ConnectionStrings["DefaultConnString"].ToString());

                DataTable dataTable1 = new DataTable();

                SqlDataAdapter sqlDA1 = new SqlDataAdapter(@"SELECT * FROM Test", sqlCon);

                SqlCommandBuilder sqlCB1 = new SqlCommandBuilder(sqlDA1);
                thro = "数据库链接有错2";
                sqlDA1.Fill(dataTable1);

                //字段名  和Execl必须一样
             
                foreach (DataRow dataRow in myDs.Tables["Test"].Rows)
                {
                    DataRow dataRow1 = dataTable1.NewRow();

                    CRM_CourseBLL coursebll = new CRM_CourseBLL();

                    dataRow1["Photo"] = dataRow[0];
                    string a = dataRow[0].ToString();
                    //判断 如果该电话存在 匹配成功
                    if (coursebll.retuntcount("CRM_Course", "ID", " where " + " C_Mobile = '" + a + "' and C_cost <> 1") > 0)
                    {
                        dataRow1["state"] = 0;
                        dataRow1["drtime"] = DateTime.Now;

                        dataTable1.Rows.Add(dataRow1);
                        drcount = drcount + 1;
                    }
                    zcount = zcount + 1;
                }
                thro = "数据填充报错";
                sqlDA1.Update(dataTable1);

                cnnxls.Close();
            }
            catch
            {
                ScriptManager.RegisterStartupScript(this, this.GetType(), "", "alert('" + fPath + thro + "');", true);
                daoruurl.InnerHtml = fPath + "---" + fPaths + thro;
                return;
            }

最后给出来的失败提示 是 保存路径出错

可是 我在服务器上面查看了 那个路径中 那个文件是存在的 求高手
