使用Xamarin形式将图像转换为字节以用于iPhone应用程序

Question

I want to convert an image to bytes for server upload. So, I have used the below code which is throwing error. Can anyone please help me out?

Error: “Reference to type 'system.componentmodel.typeconverter' claims it is defined assembly system but it could not be found".

public static byte[] imgToByteConverter(System.Drawing.Image inImg)
{
    ImageConverter imgCon = new ImageConverter();   
    return (byte[])imgCon.ConvertTo(inImg, typeof(byte[]));        
}

A Xamarin Form Image is not the same as a System.Drawing.Image. System.Drawing.Image is a W32 class and does not exist in Xamarin. You can't convert a XF image to a byte[]. Instead, you need to refer to whatever resource (file, stream, url, etc) was used to create the Image and use that to create the byte[].
