stream
答
using (Stream stream = ... fetch the stream from somewhere)
{
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
File.WriteAllBytes("foo.pdf", buffer);
}
，如果此RESTful服务使用HTTP，则可以使用 WebClient :
and if this RESTful service talks HTTP you could use a WebClient:
using (var client = new WebClient())
{
client.DownloadFile("http://example.com/api", "foo.pdf");
}
