I have an asp image control as following: 

<asp:Image ID="imagenSubida" runat="server" style="max-height:400px" />

now I want to convert the image that is stored inside that control into a byte array so that it can be stored into data base. The thing is I don't know how to make the conversion. Any help will be much apreciated.

  • Do you want to perform the conversion at post? Is the image physically stored into your directory? – Suprabhat Biswal Nov 21 '15 at 06:40
  • Hi, the image is just stored on the image control, using this code: imagenRes.ImageUrl = "data:image/png;base64," + base64String; imagenRes refers to the image control and the url was obtained from a byte array. – Ricardo Muñoz Nov 21 '15 at 06:47
