  <tr><td><asp:FileUpload runat="server" ID="fp1" /></td></tr>
  <tr><td><asp:FileUpload runat="server" ID="fp2" /></td></tr>
  <tr><td><asp:FileUpload runat="server" ID="fp3" /></td></tr>

  private void Fileupload()
        {
            if (fp1.HasFile)
                {
                   
                   
                    string filename = fp1.FileName;
                  string str=  FunchekFilealreadythere(filename);
                  String filePath = Server.MapPath(@"~/upload_resume/"+str+"/"+ fp1.FileName);
                 fp1.SaveAs(filePath);//will add file name in file name directory.
            }

                if (fp2.HasFile)
                {
                 string filename1 = fp2.FileName;
                 string str1 = FunchekFilealreadythere(filename1);
                 String filePath1 = Server.MapPath(@"~/upload_resume/" + str1 + "/" + fp2.FileName);
                 fp2.SaveAs(filePath1);

                }


                if (fp3.HasFile)
                {
                    string filename2 = fp3.FileName;
                    string str2 = FunchekFilealreadythere(filename2);
                    String filePath2 = Server.MapPath(@"~/upload_resume/" + str2 + "/" + fp3.FileName);
                    fp3.SaveAs(filePath2);

                }


           
            else
            {
                Response.Write("uploaded");
            }
        }

        public string    FunchekFilealreadythereg filename)
        {
            string nm=filename ;
            string[] fnm=new string [1];
            fnm=nm .Split ('.');//will just take file name not extension.


            if (!System.IO.Directory.Exists(Server.MapPath(@"~/upload_resume/" + fnm[0] + "")))
            {
                System.IO.Directory.CreateDirectory(Server.MapPath(@"~/upload_resume/" + fnm [0]+ ""));
            }
