Server.MapPath check for folder and create

Question

I'm uploading an image to a folder images. it's working fine.but what I actually want is to look for a folder name (I have the folder name) if not found create that folder and give it that name.how could that happen?

this is what I have done so far:

 string ImageName = System.IO.Path.GetFileName(file.FileName);
 string physicalPath = Server.MapPath("~/images/" + ImageName);

instead of images I should have folderName.

the complete view:

@{
ViewBag.Title = "Index";
}


@using (Html.BeginForm("FileUpload", "datum", FormMethod.Post,
                new { enctype = "multipart/form-data" }))
{
<div>
   category<br />
   @Html.DropDownList("category", ViewBag.Roles as SelectList)
 <br/>
   description<br />
    @Html.TextBox("description") <br />
    Image<br />
    <input type="File" name="file" id="file" value="Choose File" />
    <input type="submit" value="Upload" class="submit" />
</div>
 }

the complete controller

 public class datumController : Controller
 {
    DataEntry db = new DataEntry();
    public ActionResult Index()
    {
        var data = from p in db.categories

                   select p.categoryName;

        SelectList list = new SelectList(data);
        ViewBag.Roles = list;
        return View();
    }
    public ActionResult create ()
    {
        return View();
    }
    [HttpPost]
    public ActionResult FileUpload(HttpPostedFileBase file)
    {

        if (file != null)
        {

            string ImageName = System.IO.Path.GetFileName(file.FileName);
            string physicalPath = Server.MapPath("~/images/" + ImageName);



            // save image in folder
            file.SaveAs(physicalPath);

            //save new record in database
           datum newRecord = new datum();
            newRecord.category = Request.Form["category"];
            newRecord.description = Request.Form["description"];
            newRecord.imagePath = ImageName;
            db.data.Add(newRecord);
            db.SaveChanges();


        }
        //Display records
        return RedirectToAction("Display");
    }

so I should be getting the selected value from the drop down list and attach it to the physical path, check if folder exists if no then create folder and upload image to that folder

Try like below...

  string subPath ="ImagesPath"; // your code goes here

  bool exists = System.IO.Directory.Exists(Server.MapPath(subPath));

  if(!exists)
  System.IO.Directory.CreateDirectory(Server.MapPath(subPath));

For further info, please refer below link. If a folder does not exist, create it

Can you try to combine your category value(which is coming from dropdown) with your file name like below...Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName); please refer following link..http://stackoverflow.com/questions/5193842/file-upload-asp-net-mvc-3-0 hope this will help you.. – Vignesh Oct 28 '14 at 13:58

if (file != null && file.ContentLength > 0) 
{
    string path = Path.Combine(Server.MapPath("~/Images"), Path.GetFileName(file.FileName));
    tbl_MixEmp.EmpImage = Path.Combine("~/Images", file.FileName);
    file.SaveAs(path);
}
