Create new directory according to string

Question

I have a function that saves an image in a default directory, for all companies, and I tried to change this to save in a directory according to this string companyFolderwhich I have created. Yet you are not being saved.

How can I do that?

[HttpPost]
public JsonResult StoreImage(int idCompany)
{
    try
    {
        var companyFolder = idCompany.ToString(); 
        System.IO.Directory.CreateDirectory(Server.MapPath(companyFolder)); //creates new directory
        int numFiles = 0; //numero de imagens no diretorio da empresa

        var file = Request.Files["UploadFile"]; //arquivo que foi enviado para upload
        if ((file != null) && (file.ContentLength > 0)) //adicionar verificaçao de quantidade de imagens (para limitar a 5)
        {
            string fn = Path.GetFileName(file.FileName); //obtem nome do arquivo
            var dir = new System.IO.DirectoryInfo(Server.MapPath("~/Content/img/upload_empresa/" + companyFolder + "/")); //diretorio onde o arquivo vai ser salvo
            //var dir = new System.IO.DirectoryInfo(Server.MapPath("~/Content/img/upload_empresa/" + companyFolder));
            FileInfo[] existingImage = dir.GetFiles("imd_" + idCompany + "_*.*");

            string SaveLocation = Server.MapPath("~/Content/img/upload_empresa/" + companyFolder + "/imd_" + idCompany + "_" + existingImage.Length + Path.GetExtension(fn));

            try
            {
                file.SaveAs(SaveLocation);
            }
            catch
            {
                return Json(new { success = "false", message = "erro" });
            }
        }
    }
}

Edit: vi agora no console que é gera a seguinte exception:

Exception generated: 'System.IO.Directorynotfoundexception' in mscorlib.dll

Check if the directory that is trying to save the image exists:

if (!System.IO.Directory.Exists(SaveLocation))
  System.IO.Directory.CreateDirectory(SaveLocation)

file.SaveAs(SaveLocation);
