C#控制台进行文件写入：

using System;  using System.IO;  class file1 {      public static void Main()      {         string PATH = null;         Console.WriteLine("file path: ");//这里输入文本所在目录 例如 d:\text.txt         PATH = Console.ReadLine();         StreamWriter sw = new StreamWriter(PATH);         string str = null;         while(true){             str = Console.ReadLine();             if (str == "end") {                 break;             }             sw.WriteLine(str);         }         sw.Close();           Console.ReadKey();      }  }  

using System;  using System.IO;  class file1 {        public static void Main() {            string PATH = null;          Console.WriteLine("file path: ");//这里输入文本所在目录 例如 d:\text.txt          PATH = Console.ReadLine();          StreamReader r = File.OpenText(PATH);          while(!r.EndOfStream){              Console.WriteLine(r.ReadLine());          }          Console.ReadKey();      }  }
