Convert System.Drawing.Image to Byte Array using C# and VB.Net

Thanking you for your quick response , i have done this as the following query.

byte[] imageBytes = Convert.FromBase64String(KYCImageRequest.IDProofImageData);
MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);
ms.Write(imageBytes, 0, imageBytes.Length);
System.Drawing.Image idProofImage = System.Drawing.Image.FromStream(ms, true);
byte[] idProofBytes = ImageToByte(idProofImage);
