How can I move a downloaded file to the users temp path?-CodePudding

I've looked it up on google, tried any answers for myself and none worked. I want to download 2 files and save them both to the users temp file (C:\Users%UserName%\AppData\Local\Temp). I can easily find the temp file using a string (string tempPath = Environment.GetEnvironmentVariable("TEMP");) I just can't get farther than that at this time.

You can download directly into the temp folder:

using System.Net;

string tempPath = Environment.GetEnvironmentVariable("TEMP");

using (var client = new WebClient())
{
    client.DownloadFile("http://example.com/file/file1.txt", @$"{tempPath}\file.txt");    
    client.DownloadFile("http://example.com/file/file2.txt", @$"{tempPath}\file2.txt");
}

Or move the already downloaded file:

using System.IO;

string tempPath = Environment.GetEnvironmentVariable("TEMP");

File.Move(@"C:\User\Downloads\Filename.txt", @$"{tempPath}\file.txt");
File.Move(@"C:\User\Downloads\Filename2.txt", @$"{tempPath}\file2.txt");

The @ before the string is the string literal and The $ is the string interpolation you can search for these nice features later.

Adding to the accepted answer:

you can also derive the download-folder path to work on machine which use a different download folder as the default. You can find input on that here: How to programmatically derive Windows Downloads folder "%USERPROFILE%/Downloads"?

So if you chose to implement the second solution (moving files already downloaded) and need to roll this out on other machines than your own, this probably is a good idea.
