C# Howto convert image to binary?

Question

I have an image (.png) and I want this picture to convert to binary. How can I do this?

I am using Webforms ASP.NET C#

Answer 1

byte[] b = File.ReadAllBytes(file);

File.ReadAllBytes Method

Opens a binary file, reads the contents of the file into a byte array, and then closes the file.

Answer 2

Try this:

Byte[] result 
    = (Byte[])new ImageConverter().ConvertTo(yourImage, typeof(Byte[]));

Answer 3

Since you have a file use:-

 Response.ContentType = "image/png";
 Response.WriteFile(physicalPathOfPngFile);

Answer 4

You could do:

    MemoryStream stream = new MemoryStream();
    image.Save(stream, ImageFormat.Png);
    BinaryReader streamreader = new BinaryReader(stream);

    byte[] data = streamreader.ReadBytes(stream.Length);

data would then contain the contents of the image.

Answer 5

First, convert the image into a byte array using ImageConverter class. Then specify the mime type of your png image, and voila!

Here's an example:

TypeConverter tc = TypeDescriptor.GetConverter(typeof(Byte[]));
Response.ContentType = "image/png";
Response.BinaryWrite((Byte[])tc.ConvertTo(img,tc));
