写：string p = System.Environment.CurrentDirectory;                p = p.Replace("\\", @"\");                string path = p + @"\log.txt";//文件路径                FileStream fs = new FileStream(path, FileMode.Create);                byte[] data = new UTF8Encoding().GetBytes(name+":"+pwd1);                fs.Write(data,0,data.Length);                fs.Flush();                fs.Close();读：byte[] byData=new byte[100];                char[] charData=new char[1000];                string p = System.Environment.CurrentDirectory;                p = p.Replace("\\", @"\");                string path = p + @"\log.txt";//文件路径                try                {                    FileStream sFile = new FileStream(path, FileMode.Open);                    sFile.Seek(0, SeekOrigin.Begin);                    sFile.Read(byData, 0, 100);                    sFile.Close();                }Decoder d = Encoding.UTF8.GetDecoder();                d.GetChars(byData, 0, byData.Length, charData, 0);                string info = "";                foreach (char c in charData)                {                    info += c;                }
