How to GET data from an URL and save it into a file in binary in C#.NET without the encoding mess?

Question

In C#.NET, I want to fetch data from an URL and save it to a file in binary.

Using HttpWebRequest/Streamreader to read into a string and saving using StreamWriter works

Answer 1

Just don't use any StreamReader or TextWriter. Save into a file with a raw FileStream.

String url = ...;
HttpWebRequest  request  = (HttpWebRequest) WebRequest.Create(url);

// execute the request
HttpWebResponse response = (HttpWebResponse) request.GetResponse();

// we will read data via the response stream
Stream ReceiveStream = response.GetResponseStream();

string filename = ...;

byte[] buffer = new byte[1024];
FileStream outFile = new FileStream(filename, FileMode.Create);

int bytesRead;
while((bytesRead = ReceiveStream.Read(buffer, 0, buffer.Length)) != 0)
    outFile.Write(buffer, 0, bytesRead);

// Or using statement instead
outFile.Close()
