namespace BPRINSTALLER
{
    public partial class Form1 : Form

    {
        public Form1()
        {
            InitializeComponent();
        }

        private static byte[] DownloadFile(string url)
        {
            // Create a new WebClient object
            using (var client = new WebClient())
            {
                // Use the WebClient's DownloadData method to download the contents of the specified URL
                return client.DownloadData(url);
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            // Initialize a string variable with the URL of a file on GitHub
            string fileUrl = "https://github.com/FowningFrog/burnout_mods/blob/main/350Z/VEH_PDSVK0B_AT.BIN";
            // Call the DownloadFile method to download the contents of the file at the specified URL
            byte[] fileContents = DownloadFile(fileUrl);
            // Initialize a string variable with the file path where the downloaded file will be saved
            string filePath = @"C:\Users\UKGC\Downloads\test";
            // Use the WriteAllBytes method of the File class to write the contents of fileContents to the specified file path
            File.WriteAllBytes(filePath, fileContents);
        }
    }
}

}

Any help is appreciated <3

Is test the folder or the filename? If it's the folder, you should add the filename on WriteAllBytes' path variable. If it's actually the filename despite the lacking extension, check if there's not a folder of the same name.

Test is the name of the folder that i want to download the github file into

Then you need to add an actual filename to filePath. You could use Path.GetFileName on the fileUrl and paste it onto the filePath if you want it to have the same name.

how would i do that? im a beginner but the actual file name is Test

Malibloo•2y ago

Is it the file name or the folder? You just said it's both.

.aOP•2y ago

The name test is the name of the folder the file name im getting from github is VEH_PDSVK0B_AT.BIN

Malibloo•2y ago

Right. So you get that filename by using Path.GetFileName(), and then past that onto the end of your location. WriteAllBytes need a full path plus the filename. It doesn't just guess what the file is named.

So what would the code look like then? its hard for me to understand without examples sorry 😅

Malibloo•2y ago

I'm not sure what the rules are here about spoonfeeding, but I'm not going to write your code for you, sorry. What you need was explained in my second and fourth message.

oh it worked thank you for your time and hassle when

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
