I am using c# .net compact framework 3.5 and I want to convert a video file to byte array so that I may upload it on the server.
In the similar manner I am doing the image uploading which is getting the success result.
HttpWebRequest request;
request.ContentType = "image/jpeg";
request.ContentLength = byteArray.Length;
request.Method = "PUT";
imageToByteArray(img).CopyTo(byteArray, 0);
using (Stream requestStream = request.GetRequestStream())
{
requestStream.Write(byteArray, 0, (int)Fs.Length);
requestStream.Flush();
requestStream.Close();
}
public byte[] imageToByteArray(Image imageIn)
{
MemoryStream ms = new MemoryStream();
imageIn.Save(ms,System.Drawing.Imaging.ImageFormat.Jpeg);
return ms.ToArray();
}
How to do this for the video files?
You should copy the stream one block at a time instead of reading the entire file into an array. Otherwise, you'll use a potentially very large amount of memory as video files can grow quite big.
For example:
HttpWebRequest request;
request.Method = "PUT";
using(Stream requestStream = request.GetRequestStream())
using(Stream video = File.OpenRead("Path")) {
byte[] buffer = new byte[4096];
while(true) {
int bytesRead = video.Read(buffer, 0, buffer.Length);
if (bytesRead == 0) break;
requestStream.Write(buffer, 0, bytesRead);
}
}
