            char[] m_cDataWrite = new char[100];
            try
            {
                FileStream m_filestream = new FileStream(@"G:\file.txt", FileMode.OpenOrCreate);
                m_cDataWrite = "My First File Operation".ToCharArray();
                Encoder m_enc = Encoding.UTF8.GetEncoder();
                m_enc.GetBytes(m_cDataWrite, 0, m_cDataWrite.Length, m_bDataWrite,0,true);
                m_filestream.Seek(0, SeekOrigin.Begin);
                m_filestream.Write(m_bDataWrite, 0, m_bDataWrite.Length);
            }
            catch (IOException e)
            {
                Console.WriteLine(e.ToString());

            Console.ReadLine();
        }
    }
}各位大哥 我为什么在文件中写不进去东西啊？ 恳请告知哪错了

Answer 1

m_filestream.Seek(0, SeekOrigin.Begin);
m_filestream.Write(m_bDataWrite, 0, m_bDataWrite.Length);
//增加下面的代码
m_filestream.Flush();//清除缓冲区
m_filestream.Close();//关闭文件流

Answer 2

//文本文件的读写，参考：using System.IO;using (StreamWriter vStreamWriter = new StreamWriter(
    @"c:\temp\temp.txt", false, Encoding.Default))
    vStreamWriter.Write("Zswang 路过");using (StreamReader vStreamReader = new StreamReader(
    @"c:\temp\temp.txt", Encoding.Default))
    textBox1.Text = vStreamReader.ReadToEnd();

Answer 3

m_filestream.Flush();//清除缓冲区
m_filestream.Close();//关闭文件流
LS,YES
