Overview : async awit, async void 를 구현해 본다.
1.async awit (net.core)

public async Task ProcessWriteAsync() { string filePath = "temp.txt"; string text = $"Hello World{Environment.NewLine}"; await WriteTextAsync(filePath, text); } async Task WriteTextAsync(string filePath, string text) { byte[] encodedText = Encoding.Unicode.GetBytes(text); using var sourceStream = new FileStream( filePath, FileMode.Create, FileAccess.Write, FileShare.None, bufferSize: 4096, useAsync: true); await sourceStream.WriteAsync(encodedText, 0, encodedText.Length); } |
2.async void (.net)
기다리지 않고 파일 쓰기
