Right now I am using this code to download files (with a Range header). Most of the files are large, and it is running 99% of CPU currently as the file downloads. Is there any way that the file can be written periodically so that it does not remain in RAM constantly?
private byte[] GetWebPageContent(string url, long start, long finish)
{
byte[] result = new byte[finish];
HttpWebRequest request;
request = WebRequest.Create(url) as HttpWebRequest;
//request.Headers.Add("Range", "bytes=" + start + "-" + finish);
request.AddRange((int)start, (int)finish);
using (WebResponse response = request.GetResponse())
{
return ReadFully(response.GetResponseStream());
}
}
public static byte[] ReadFully(Stream stream)
{
byte[] buffer = new byte[32768];
using (MemoryStream ms = new MemoryStream())
{
while (true)
{
int read = stream.Read(buffer, 0, buffer.Length);
if (read <= 0)
return ms.ToArray();
ms.Write(buffer, 0, read);
}
}
}
