[C#/WINUI3/.NET8] DataReader 클래스 : ReadBytes 메소드를 사용해 바이트 배열 읽기

■ DataReader 클래스의 ReadBytes 메소드를 사용해 바이트 배열을 읽는 방법을 보여준다.

▶ 예제 코드 (C#)


using Windows.Storage;
using Windows.Storage.Streams;

StorageFolder storageFolder = await StorageFolder.GetFolderFromPathAsync(@"D:\");

StorageFile storageFile = await storageFolder.GetFileAsync("sample.txt");

using IRandomAccessStream randomAccessStream = await storageFile.OpenReadAsync();

IInputStream inputStream = randomAccessStream.GetInputStreamAt(0);

using DataReader dataReader = new DataReader(inputStream);

await dataReader.LoadAsync((uint)randomAccessStream.Size);

byte[] byteArray = new byte[randomAccessStream.Size];

dataReader.ReadBytes(byteArray);
