I am working in Monotouch framework, in which i have to show image, what i have is byte[].
so i used
Public static Public static UIImage GetImagefromByteArray (byte[] byteArrayI开发者_如何转开发n){
using (MemoryStream memStream = new MemoryStream ())
{
byte[] streamBytes = new byte [byteArrayIn.Length];
memStream.Read( streamBytes, 0, byteArrayIn.Length);
NSData data = NSData.FromArray( streamBytes );
return UIImage.LoadFromData( data );
}
}
but it always returns null, i searched for it so came to know that it is a bug in monotouch. bug reported link, so what else function may i use to show image .
Your code is wrong. You are reading from an empty MemoryStream. UIImage.LoadFromData works fine in MonoTouch 4.0 (and since 3.2.* from what I can remember). Try the following method, you don't need a MemoryStream if you already have the byte buffer of the image, eg. from a FileStream:
public static UIImage GetImagefromByteArray (byte[] imageBuffer)
{
NSData imageData = NSData.FromArray(imageBuffer);
return UIImage.LoadFromData(imageData);
}
