byte[] 转换 Bitmap

public static Bitmap BytesToBitmap(byte[] Bytes) 
{ 
	MemoryStream stream = null; 
	try 
	{ 
		stream = new MemoryStream(Bytes); 
		return new Bitmap((Image)new Bitmap(stream)); 
	} 
	catch (ArgumentNullException ex) 
	{ 
		throw ex; 
	} 
	catch (ArgumentException ex) 
	{ 
		throw ex; 
	} 
	finally 
	{ 
		stream.Close(); 
	}
