从图像创建字节数组 [英] Creating a Byte array from an Image

问题描述

从图像创建字节数组的最佳方法是什么?我见过很多方法，但在 WinRT 中它们都不起作用.

What is the best way to create a byte array from an Image? I have seen many methods but in WinRT none of them worked.

推荐答案

static class ByteArrayConverter
    {
        public static async Task<byte[]> ToByteArrayAsync(StorageFile file)
        {
            using (IRandomAccessStream stream = await file.OpenReadAsync())
            {
                using (DataReader reader = new DataReader(stream.GetInputStreamAt(0)))
                {
                    await reader.LoadAsync((uint)stream.Size);
                    byte[] Bytes = new byte[stream.Size];
                    reader.ReadBytes(Bytes);
                    return Bytes;
                }
            }
        }
    }
