C#文字檔或其他檔案新內容追加

以txt文本為例，以下代碼實現a.txt檔案中追加內容

FileStream mystream = new FileStream("C:\\a.txt", FileMode.OpenOrCreate);            StreamWriter Mywriter = new StreamWriter(mystream, Encoding.Default);            string text = "";            for (int i = 0; i < axMSFlexGrid1.Rows; i++)                for (int j = 0; j < axMSFlexGrid1.Cols; j++)                    text += flex.get_TextMatrix(i, j) + "\t";            Mywriter.Write(text);            Mywriter.Close();            mystream.Close();

這種方式也可以：

FileStream fs = null;            string filePath = "C:\\file.txt";            Encoding encoder = Encoding.UTF8;            byte[] bytes = encoder.GetBytes("Hello World! \n\r");            try            {                fs = File.OpenWrite(filePath);               fs.Position = fs.Length;              fs.Write(bytes, 0, bytes.Length);            }            catch (Exception ex)            {                Console.WriteLine("檔案開啟失敗{0}", ex.ToString());            }            finally            {                fs.Close();            }  

用的最多的還是這種

 StreamWriter sw=File.AppendText("c:\\Text.txt"); sw.WriteLine("13"); sw.WriteLine("22222"); sw.WriteLine("88888"); sw.Flush(); sw.Close();
