I'm trying to upload files to my computer from another device connected to the same network. I already can view and download files from my computer on my smartphone, but I still don't know how can I upload files from my smartphone to my computer.
I'm using IIS on windows 10 on my computer to host files over private ip (so it works on the same network)
I have found example to upload files on https://docs.microsoft.com/en-us/troubleshoot/aspnet/upload-file-to-web-site , but when I try to implement it, it gives me error, that it can't load type 'upload.WebForm1'
. I have deleted all the code except using directives, spacename and class. Here is the code:
WebForm1.aspx
<%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false"
Inherits="upload.WebForm1" %>
When I include the rest stackoverflow says red: Your post appears to contain code that is not properly formatted as code. Please indent all code by 4 spaces using the code toolbar button or the CTRL K keyboard shortcut. For more editing help, click the [?] toolbar icon. and not let me post question.
Rest of .aspx document is copied and not changed from complete code listing from the link above.
WebForm1.aspx.cs
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.IO;
namespace upload {
public class WebForm1 : System.Web.UI.Page
{
}
}
Any ideas what's wrong?

Can you try changing Codebehind to CodeFile
