How to convert Video to byte Array in C#?

.net, c#, compact-framework, file-upload, windows-mobile

Solution

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);
    }
}

Problem

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?
