问在内存中对文本文件进行内存操作的最佳方法:首先读取为byte[]？读取为File.ReadAllText()，然后保存为二进制？

EN

MemoryStream stream = new MemoryStream();
stream.Write(byteData, 0, byteData.Length);

using (var reader = File.OpenText(originalFile))
using (var writer = File.CreateText(tempFile))
{
    string line;
    while ((line = reader.ReadLine()) != null) 
    {
        var temp = DoMyStuff(line);
        writer.WriteLine(temp);
    }
}

File.Delete(originalFile);
File.Move(tempFile, originalFile);
