Please help - Convert Image file to bytes

[Bobski]

Hi guys,

How do i go about converting images files like jpeg's in to bytes?

Im doing the work in c#, the .net 2.0 platform, if that makes any difference...

really need some help on this, thanks!

in asp.net 1.1 i use HttpPostedFile and use the "InputStream.Read" method of it .

something like this

HttpPostedFile theFile = this.myFile.PostedFile; 
byte[] uploadData = new Byte[nFileLen]; //nFileLen is the size of the file in bytes
theFile.InputStream.Read(uploadData,0,nFileLen);
//the above line reads the posted file into a byte array called uploadData.

then uploadData has all the bytes in an array, and you can flush it or write it to a new file.

hth,
mcm

Is the file on your computer? You could try the following:

foreach(Byte b in File.ReadAllBytes(@"c:\test\sunset.jpg"))
    Console.Write("{0} ", b.ToString("X2"));

[MadHatter]

byte[] bytes = null;
using( MemoryStream ms = new MemoryStream() ) {
    myBmp.Save(ms, ... );
    ms.Seek(0,0);
    bytes = ms.ToArray();
}
// bytes contains the image

Yeh mate this seems to work, thx.

Im basically trying to change it into bytes so i can send it over a bluetooth connection using OBEX to a mobile device. All i need to know now is how to convert this back to an image so i can display it on the phone. Oh how i love programming ;-)


Thanks
