C# - Simple FileStream Write and Read

FileStream Write

string s = "abc 中文字";
var buffer = Encoding.UTF8.GetBytes(s);
var fs = new FileStream(@"Z:\test.txt", FileMode.Create);
fs.Write(buffer, 0, buffer.Length);
fs.Close();

FileStream Simple Read

在這裡暫不考慮讀進來的 Encoding 問題，所以直接用 UTF-8

var fs = new FileStream(@"Z:\test.txt", FileMode.Open);
var buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
var s = Encoding.UTF8.GetString(buffer);
