How to get bytes out of a PNG file using C#

Question

How do I get bytes out of a PNG file using C#, (Reason for this:I need to pass the PNG as a string in an XML file.)

Answer 1

System.IO.File.ReadAllBytes

System.Convert.ToBase64String

System.Convert.ToBase64String(System.IO.File.ReadAllBytes(filePath));

Answer 2

Alternatively, if you have the PNG file in memory:

• create a System.Drawing.Bitmap object out of it
• Serialize it to a memory stream using Bitmap.Save() (pass in PNG as the encoding)
• Use MemoryStream.GetBuffer() to retrieve the underlying byte array for the MS
• Use Convert.ToBase64String(byte[], 0, memoryStream.Position) to convert it to a base64 string
