Controller:

          var model = new Tickets();
          PopulateLists(model);


          return View("Create");
      }

      // POST: Tickets/Create
      [HttpPost]
      public ActionResult Create(Tickets model, HttpPostedFileBase files)
      {
          if (files != null && files.ContentLength > 0)
          {
              model.File1 = new byte[files.ContentLength];
              files.InputStream.Read(model.File1, 0, files.ContentLength);
              model.File2 = new byte[files.ContentLength];
              files.InputStream.Read(model.File2, 0, files.ContentLength);
              model.File3 = new byte[files.ContentLength];
              files.InputStream.Read(model.File3, 0, files.ContentLength);
          }
          if (ModelState.IsValid)
          {

              PopulateLists(model);
              _db.Tickets.Add(model);
              _db.SaveChanges();
              // TODO: Add insert logic here
              return RedirectToAction("Tickets");
          }

          return View("Tickets");
      }

Model:

//omitted above code, not related to this section of code everything above here works fine.
public byte[] File1 { get; set; }
public byte[] File2 { get; set; }
public byte[] File3 { get; set; }

View:

//omitted not related to this section of code, everything above here works fine,

<div class="form-group">
           
            <div class="col-md-offset-2 col-md-10">
                <input type="file" id="File1" name="File1"/>
            </div>
           
            <div class="col-md-offset-2 col-md-10">
                <input type="file" id="File2" name="File2" />
            </div>
            
            <div class="col-md-offset-2 col-md-10">
                <input type="file" id="File3" name="File3" />
                <h3 />
            </div>
        </div>

Just now getting to the point in my project that I want to upload files, I have a pretty good idea of how I am going to add it to the project, however what fields would I use in database table to (I should say type of fields) If Or do you recommend something else?

Keep in mind I am using C#6, MVC5/6 Razor sql database and asp.net with entity framework, anything else you need to know ask, but ask clearly because I can still misunderstand since I am a newbie. Thank you all for your suggestions in advance!

What I have tried:

still researching before implementing anything in project... I am newish (4 months self teaching)

You code fails because you try to base64 decode a string that is not base64 encoded.
The problem is not in your code, at least not now.
You need to show the offending string to identify the encoding, then, after, change the code to handle the encoding.

As far as I can see, the code in your question is not related to base64 decoding.

I don't eve know where to start, I tried to follow a few examples on this website and others for base64, and I cant seem to get it to work, it keeps giving the same error.

Run your code on debugger and when you get the error, inspect the variable that is supposed to hold the base64 value and update your question with that value, this way, we can see what you try to decode.
Nota: the only code interesting is where the error occurs.
