I have used AjaxFileUpload to upload multiple image files. Now i want to store the uploaded images inside rootfolder>subfolder.

The rootfolder is in the name of the user.
The rootfolder is created dynamically by taking the session of the user who has logged in
Like this:

string username = Session["username"].ToString();

I am able to create this folder and save images in it. but i want to save it in subfolder.

the subfolder is also created dynamically but this time i have to take the value(id) from the database and name the folder by that id name. (this is so that i can refer to the database)

I know how to create a new folder using Server.MapPath();
Here is the code for it in brief

using System.IO
    if (Directory.Exists(Server.MapPath(uploadPath))) return;
    else Directory.CreateDirectory(Server.MapPath(uploadPath));

where uploadPath is the folder's name i want to create dynamiclly.

but how do I include the subfolder too in my Server.MapPath() so as to make my path as rootfolder/subfolder ?

Small example to make the question understandable.
I am a seller. I have posted 4 ads online.
Now when i am posting my 5th ad i want to include many images.
these images should be saved in the folder

Seller/5/imagename.jpg.
(where Seller is the username(main folder), 5 is the advertID in the database and the name of the subfolder)

How do i do this? Please help.
I am using asp.net c#

What's your question? How do you add a subfolder in Server.MapPath? You just add it on the string so I am not sure what your question is.

My question is how do I name the dynamically created subfolder with a value stored in the database. i.e. i need to create and name it simultaneously and the naming should take a value from the database. How can I do that? Can i do that in Server.MapPath()?

After your Server.MapPath then just add on the part from the db and created the directory as Solution 1 points out.

check this code

C#

string subfolderPath = System.Web.HttpContext.Current.Server.MapPath("~");
                       string subfolderName = "get from data base";
                       subfolderPath += "\\"+subfolderName+"\\";
                       if (!System.IO.Directory.Exists(subfolderPath))
                           System.IO.Directory.CreateDirectory(subfolderPath);
