how to upload image in C# MVC

I have a new question, I would like to save image in my .NET MVC application from razor view, but as i am new mvc C# developer i don't have much knowledge in it.
As i understand till now, i need to send form with method post and enctype ="multipart/form-data"

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new { enctype = "multipart/form-data" })
{

 <input type="file" name="ImageFile" id="ImageFile" />

<input type="submit" value="Submit" id="Submit" />
}

There are sevaral methods on many websites related to ajax, C# etc, but i want the simplest one , which is easier to understand, and can be implemented quickly.

yes your form is correct, you can now write this code in your controller to get the image in the back end

 // This code can be used for multiple files upload also
       [HttpPost]
        public ActionResult ImageUpload()
        {
           
            if (Request.Files.Count > 0)
            {
                try
                {
                    //  Get all files from Request object  
                    HttpFileCollectionBase files = Request.Files;
                    var savedurl = "";
                    for (int i = 0; i < files.Count; i++)
                    {
                        //string path = AppDomain.CurrentDomain.BaseDirectory + "Uploads/";  
                        //string filename = Path.GetFileName(Request.Files[i].FileName);  

                        HttpPostedFileBase file = files[i];
                        string fname;

                        // Checking for Internet Explorer  
                        if (Request.Browser.Browser.ToUpper() == "IE" || Request.Browser.Browser.ToUpper() == "INTERNETEXPLORER")
                        {
                            string[] testfiles = file.FileName.Split(new char[] { '\\' });
                            fname = testfiles[testfiles.Length - 1];
                        }
                        else
                        {
                            fname = file.FileName;
                        }
                        string subPath = "~/Images/Upload/"; 

                        bool exists = System.IO.Directory.Exists(Server.MapPath("~/Images/Upload/"));

// if Folder doesn't exists create it
                        if (!exists)
                        { 
System.IO.Directory.CreateDirectory(Server.MapPath("~/Images/Upload/")); 
}
                        // Get the complete folder path and store the file inside it.  
                        fname = Path.Combine(Server.MapPath("~/Images/Upload/"), fname);

                       //save file on server
                        file.SaveAs(fname);
//you can save it in database also if you need it, but it is not recommended solution
                    }
                    // Returns message that successfully uploaded  
                    return Json(new { MSG="File Uploaded Successfully!" , SAvedUrl= savedurl },JsonRequestBehavior.AllowGet);
                }
                catch (Exception ex)
                {
                    return Json("Error occurred. Error details: " + ex.Message);
                }
            }
            else
            {
                return Json("No files selected.");
            }
        }

Saving files on a server is better than saving it database, as it increases database calls.
