C#写入TXT文本文件

private void TxtWrite(string strToWrite,string filename)
{
    FileStream fs = new FileStream(filename, FileMode.Create, FileAccess.Write);
    StreamWriter sw = new StreamWriter(fs);
    sw.BaseStream.Seek(0, SeekOrigin.Begin);
    sw.WriteLine(strToWrite);
    sw.Close();
}

如果写入txt文件，/n应该用Environment.NewLine代替
