C# ByteArray to Image -

i need convert byte[] image, cannot make work in c#. if save bytearray file this:

using (system.io.filestream fs = system.io.file.create("test.jpg")) {     fs.write(bytearray, 0, (int)lenght);     fs.close(); } 

and test.jpg shows properly. when try make image bytearray this:

memorystream ms = new memorystream(bytearray); picturebox1.image = image.fromstream(ms); 

it shows black box.

i guess 1 problem since creating test.jpg, doesn't have data , bytearray empty.

do :-

            byte[] filedata = null;             using (var fs = new filestream("c:\\1\\roses.jpg", filemode.open, fileaccess.read))                 {                 var totallength = (int)fs.length;                 using (var binaryreader = new binaryreader(fs))                     {                     filedata = new byte[totallength];                     fs.read(filedata, 0, totallength);                     fs.close();                     }                 memorystream ms = new memorystream(filedata);                 picturebox1.image = image.fromstream(ms);                 }
