C#控制台进行文件读写的简单范例

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();
    }
}
