Ola, estou baixando alguns arquivos, a parte de baixar está Ok, mas agora preciso limitar a velocidade, mas estou com problema ao tentar fazer isto. Eu preciso
da limitação pôs não quero "matar" minha internet.
A última cosia que tentei foi:
public static int BYTEDOWN { get; private set; }
public static int MAX_SPEED { get; private set; } = 0;
public static void HttpDownloadFile(string url, string path, int timeOut = 20000, string headers = "", long startByte = 0, long expectByte = -1)
{
// Speed
System.Timers.Timer timer = new System.Timers.Timer(1000); //Instantiate the Timer class
timer.AutoReset = true;
timer.Enabled = true;
timer.Elapsed += delegate
{
Console.WriteLine("Speed: " + Global.FormatFileSize((BYTEDOWN)) + " / s"); // Convert To Mb | Kb.
var spd = Global.FormatFileSize((BYTEDOWN));
if (BYTEDOWN <= Global.STOP_SPEED * 1024)
{
Console.WriteLine("Speed: " + Global.FormatFileSize((BYTEDOWN)) + " / s "); // Convert To Mb | Kb.
}
else
{
BYTEDOWN = 0;
}
};
// Downlaod
try
{
if (File.Exists(path))
File.Delete(path);
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Timeout = timeOut;
request.ReadWriteTimeout = timeOut; //important
request.AllowAutoRedirect = true;
request.KeepAlive = false;
request.Method = "GET";
long totalLen = 0;
long downLen = 0;
using (var response = (HttpWebResponse)request.GetResponse())
{
using (var responseStream = response.GetResponseStream())
{
using (var stream = new FileStream(path, FileMode.Create, FileAccess.Write, FileShare.Write))
{
//responseStream.CopyTo(stream);
totalLen = response.ContentLength;
byte[] bArr = new byte[1024];
int size = responseStream.Read(bArr, 0, (int)bArr.Length);
while (size > 0)
{
stream.Write(bArr, 0, size);
downLen += size;
BYTEDOWN += size; //Calculate download speed
if (MAX_SPEED != 0)
while (BYTEDOWN >= MAX_SPEED * 1024 ) //Speed limit
{
Thread.Sleep(1);
}
size = responseStream.Read(bArr, 0, (int)bArr.Length);
}
}
}
}
if (totalLen != -1 && downLen != totalLen)
try { File.Delete(path); } catch (Exception) { }
}
catch (Exception e)
{
try { File.Delete(path); } catch (Exception) { }
}
timer.Enabled = true;
}
Outra tentativa:
while (size > 0)
{
sw.Start();
stream.Write(bArr, 0, size);
downLen += size;
BYTEDOWN += size; //Calculate download speed
//if (MAX_SPEED != 0)
//{
// while (BYTEDOWN >= MAX_SPEED * 1024) //Speed limit
// {
// Thread.Sleep(1);
// }
//}
if(MAX_SPEED > 0)
{
if(BYTEDOWN >= MAX_SPEED * 1024)
{
while (sw.ElapsedMilliseconds <=1000)
{
Thread.Sleep(1);
}
sw.Reset();
}
}
size = responseStream.Read(bArr, 0, (int)bArr.Length);
}
