在UWP中将BitmapImage转换为byte[]并在SQLite中插入,可以按照以下步骤进行操作: 首先,需要将BitmapImage转换为byte[]。可以使用以下代码实现: 代码语言:txt 复制 public byte[] ConvertBitmapImageToByteArray(BitmapImage image) { using (MemoryStream stream = new MemoryStream()) { WriteableBitmap bit...
代码如下：ByteArrayOutputStream output = new ByteArrayOutputStream();//初始化一个流对象bmp.compress(CompressFormat.PNG, 100, output);//把bitmap100%高质量压缩 到 output对象里bmp.recycle();//自由选择是否进行回收byte[] result = output.toByteArray();//转换成功了try {output.close()...
