バイト配列がどのエンコーディングで格納されているか知っていますか?
Encoding.GetStringメソッドが必要です
これがMSDNの例です
using System;
using System.IO;
using System.Text;
public class Example
{
const int MAX_BUFFER_SIZE = 2048;
static Encoding enc8 = Encoding.UTF8;
public static void Main()
{
FileStream fStream = new FileStream(@".\Utf8Example.txt", FileMode.Open);
string contents = null;
// If file size is small, read in a single operation.
if (fStream.Length <= MAX_BUFFER_SIZE) {
Byte[] bytes = new Byte[fStream.Length];
fStream.Read(bytes, 0, bytes.Length);
contents = enc8.GetString(bytes);
}
// If file size exceeds buffer size, perform multiple reads.
else {
contents = ReadFromBuffer(fStream);
}
fStream.Close();
Console.WriteLine(contents);
}
private static string ReadFromBuffer(FileStream fStream)
{
Byte[] bytes = new Byte[MAX_BUFFER_SIZE];
string output = String.Empty;
Decoder decoder8 = enc8.GetDecoder();
while (fStream.Position < fStream.Length) {
int nBytes = fStream.Read(bytes, 0, bytes.Length);
int nChars = decoder8.GetCharCount(bytes, 0, nBytes);
char[] chars = new char[nChars];
nChars = decoder8.GetChars(bytes, 0, nBytes, chars, 0);
output += new String(chars, 0, nChars);
}
return output;
}
}
// The example displays the following output:
// This is a UTF-8-encoded file that contains primarily Latin text, although it
// does list the first twelve letters of the Russian (Cyrillic) alphabet:
//
// А б в г д е ё ж з и й к
//
// The goal is to save this file, then open and decode it as a binary stream.
