ありがとう、ジャスティン、
これが私がそれをやった方法です:
auto folder = Windows::Storage::ApplicationData::Current->LocalFolder;
Concurrency::task<Windows::Storage::StorageFile^> createFileOp(
folder->CreateFileAsync(L"Data.bin", Windows::Storage::CreationCollisionOption::ReplaceExisting));
createFileOp.then(
[nData, pData](Windows::Storage::StorageFile^ file)
{
return file->OpenAsync(Windows::Storage::FileAccessMode::ReadWrite);
})
.then([nData, pData](Windows::Storage::Streams::IRandomAccessStream^ stream)
{
auto buffer = ref new Platform::Array<BYTE>(pData, nData);
auto outputStream = stream->GetOutputStreamAt(0);
auto dataWriter = ref new Windows::Storage::Streams::DataWriter(outputStream);
dataWriter->WriteBytes(buffer);
return dataWriter->StoreAsync();
})
.wait();
それを私が「意味した」ものと比較してください:
FILE *fp = fopen("Data.bin", "wb");
if (fp)
{
int ret = fwrite(pData, 1, nData, fp);
fclose(fp);
}
