Question

你好我正在学习windows phone 8，我有保存文件的问题，基本上我从web服务下载zip文件，我需要保存它，但我无法做到这一点。我想保存inStream的内容有什么建议吗？

private async Task saveSetupFile(Stream inStream)
    {

        StorageFolder local = Windows.Storage.ApplicationData.Current.LocalFolder;

        var myFolder = await local.CreateFolderAsync("AuditsSetupFiles", CreationCollisionOption.OpenIfExists);


        var file = await myFolder.CreateFileAsync("EquipSetup.zip", CreationCollisionOption.ReplaceExisting);

        var outStream = await file.OpenStreamForWriteAsync();

        byte [] buffer = new byte[1024];
        int len;

        using (var s = await file.OpenStreamForWriteAsync())
        {

        }

这应该有效：

private async Task SaveSetupFile(Stream inStream)
{
    var localFolder = ApplicationData.Current.LocalFolder;
    var folder = await localFolder.CreateFolderAsync("AuditsSetupFiles", CreationCollisionOption.OpenIfExists);
    var file = await folder.CreateFileAsync("EquipSetup.zip", CreationCollisionOption.ReplaceExisting);

    using (var outStream = await file.OpenStreamForWriteAsync())
    {
        await inStream.CopyToAsync(outStream);
    }
}
