Trying to Upload and Image.

C#

if (FileUpload1.HasFile)
            {
                string imagename = System.IO.Path.GetFileName(FileUpload1.FileName);
                string ext = System.IO.Path.GetExtension(FileUpload1.FileName);
                string imagefile = Server.MapPath("Pictures/" + imagename + ext);
                byte[] Image = null;
                if (ext == ".jpg" | ext == ".gif" | ext == ".png")
                {
                    Image = new byte[FileUpload1.PostedFile.ContentLength];
                    HttpPostedFile UploadedImage = FileUpload1.PostedFile;
                    UploadedImage.InputStream.Read(Image, 0, (int)FileUpload1.PostedFile.ContentLength);
                    int numBytesToRead = Image.Length;
                    try
                    {
                        using (FileStream fsNew = new FileStream(imagefile, FileMode.Create, FileAccess.Write))
                        {
                            fsNew.Write(Image, 0, numBytesToRead);
                        }
                    }
                    catch (FileNotFoundException ioEx)
                    {
                        Label100.Text = "Filestream Add Pictures: " + ioEx.ToString();
                    }
                }

This worked for me(just have to change where I have the [MyDestinationPath]

private string Upload(HttpPostedFileBase file)
{
string path = string.Empty;

try
{
if ((file != null) && (file.ContentLength > 0) && !string.IsNullOrEmpty(file.FileName))
{
FileInfo filepath = new FileInfo(file.FileName);
string fileName = file.FileName;
string fileContentType = file.ContentType;
byte[] fileBytes = new byte[file.ContentLength];
file.InputStream.Read(fileBytes, 0, Convert.ToInt32(file.ContentLength));
path = string.Concat([MyDestinationPath], filepath.Name);
file.SaveAs(Server.MapPath(path));

return path;
}
}
catch (Exception ex)
{

}

return path;
}

"Doesn't work" does not give anyone enough information to help you. Do you phone a mechanic and say "my car doesn't work, how do I fix it?"

Debug your code and step through it to get a better understanding of what it is doing\not doing, then provide that information in the question along with any error messages you get and on what line they occur.

Check the permissions to the directory you are trying to save the file to.
The account running the web-site will not have write permissions to the file system by default, if it did you would be able to upload any type of file to the website.

Kind Regards
