C#读写文本文件源码片段

下边内容段是关于C#读写文本文件片段的内容，应该是对码农们也有用。

using System;
using System.IO;
public class TestReadFile
{
public static void Main(String[] args)
{
FileStream fs = new FileStream(@c:temptest.txt , FileMode.Open, FileAccess.Read);
StreamReader sr = new StreamReader(fs);

String line=sr.ReadLine();
while (line!=null)
{
Console.WriteLine(line);
line=sr.ReadLine();
}

sr.Close();
fs.Close();
}
}
