How do I make a button in C# that executes a file without being installed on the machine?-CodePudding

So I recently wanted to try out C# and make an app that executes a file on a button click without the file being installed on the machine so the button downloads it silently and executes it once downloaded.

So I tried the following code hoping that it will execute the .exe but it only downloaded it without running it. Here's the full code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Diagnostics;
using System.Net;
using System.IO;

namespace InvizCheatz_Loader
{
    public partial class InvizCheatz : Form
    {
        public InvizCheatz()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            System.Diagnostics.Process.Start("https://invizcheatz.com/Downloads/CF-Multi_Tool.exe");
        }
    }
}

The above code downloaded the file although I wanted to do it silently open it automaticaly.

CodePudding user response：

you have to download the file before you can start it!

    private void button1_Click(object sender, EventArgs e)
    {
        string LinkToFile = @"https://invizcheatz.com/Downloads/CF-Multi_Tool.exe";
        string FileName = "CF-Multi_Tool.exe";

        string filePath = DownloadFile(LinkToFile, FileName);
        StartFile(filePath);
    }


    string DownloadFile(string link, string fileName)
    {
        WebClient wc = new WebClient();
        //download the file and renamed it
        wc.DownloadFile(link, fileName);
        //return the path where the file is
        return Environment.CurrentDirectory   "\\"   fileName;
    }

    void StartFile(string filePath)
    {
        //start the process
        System.Diagnostics.Process.Start(filePath);
    }
