Why can't I upload a file from a folder to the server via UploadFile?

Question

css

I'm trying to upload a file from the TEST folder in the root of the program to the server

var wc = new WebClient();
var responseFile = Encoding.ASCII.GetString(wc.UploadFile(p, "TEST\\test.txt"));  // p - адрес загрузки

Gives an error message

"{\"error\":\"empty_file\",\"error_descr\":\"empty_file\",\"error_is_logged\":false}"

But if you try to download a file from the root folder of the program, and not from a subfolder, then everything works out

var wc = new WebClient();
var responseFile = Encoding.ASCII.GetString(wc.UploadFile(p, "test.txt"));  // p - адрес загрузки

Answer 1

You can try this option

Answer 2

The problem was that the files were empty. After filling the file with information - everything turned out.

Answer 3

Try

var responseFile = Encoding.ASCII.GetString(wc.UploadFile(p, @".\TEST\test.txt"));  // p - адрес загрузки
