C# – WebClient generates (401) Unauthorized error

I just found the solution and yea it was easier than I thought :)

so here is the solution:

string URI = "http://www.myurl.com/post.php";
string myParameters = "param1=value1&param2=value2&param3=value3";

using (WebClient wc = new WebClient())
{
    wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
    string HtmlResult = wc.UploadString(URI, myParameters);
}

it works like charm :)

Are you using basic auth on your iis/apache? If so try this:

$source = "http://repository/folder/File.exe"
$destination = "E:\Temp\File.exe"
$wc = new-object System.Net.WebClient
$credCache = new-object System.Net.CredentialCache
$creds = new-object System.Net.NetworkCredential($user,$pwd)
$credCache.Add($source, "Basic", $creds)
$wc.Credentials = $credCache
$wc.DownloadFile($source, $destination)
