要用到文件操作,File.ReadAllLines(path); path是路径,从文本里面读取所有行,返回一个string 数组。
不懂可以查MSDN,转一个来自MSDN的例子。
- using System;
- using System.IO;
- class Test
- {
- public static void Main()
- {
- string path = @"c:\temp\MyTest.txt";
- // This text is added only once to the file.
- if (!File.Exists(path))
- {
- // Create a file to write to.
- string[] createText = { "Hello", "And", "Welcome" };
- File.WriteAllLines(path, createText);
- }
- // This text is always added, making the file longer over time
- // if it is not deleted.
- string appendText = "This is extra text" + Environment.NewLine;
- File.AppendAllText(path, appendText);
- // Open the file to read from.
- string[] readText = File.ReadAllLines(path);
- foreach (string s in readText)
- {
- Console.WriteLine(s);
- }
- }
- }
