楼上的都对。
推荐一篇不错的Knowledge Base文章：如何在 Visual C# 中执行基本的文件 I/O。kb304430

[小y的CSDN博客]

//读ini文件
public static ArrayList ReadIniFile()
{
//从文件config.ini中读取数据
StreamReader myrd=new StreamReader(filePath,Encoding.Default);
ArrayList tempstr=new ArrayList();
while(myrd.Peek()>=0)
{
tempstr.Add(myrd.ReadLine());
}
myrd.Close();
return tempstr;
}
//将ArrayList重新写入到文件中
public static void WriteIniFile(ArrayList content)
{
FileStream fs = new FileStream(filePath,FileMode.Create, FileAccess.Write, FileShare.None);
StreamWriter mywt=new StreamWriter(fs,Encoding.Default);
IEnumerator myEnumerator = content.GetEnumerator();
while (myEnumerator.MoveNext())
mywt.WriteLine(myEnumerator.Current);
mywt.Flush();
mywt.Close();
fs.Close();
}

在MSDN或者Google搜索System.IO.File

[xyq1986]

FileStream类，Read,Write方法，
还有很多啦
File.ReadAllText (String)
……

[leohuang]

//写
System.IO.StreamWriter sw = System.IO.File.CreateText(path);
sw.Write("往里写吧");
//写完了close
sw.Close();

//读
System.IO.StringReader sr = System.IO.File.OpenText("文件路径");
string all = sr.ReadToEnd();//读所有的
string line = sr.ReadLine();//一行一行的读
sr.Close();//关闭

参见MSDN:

直接看帮助，里面详细的说明了。帮助索引key:StreamReader,StreamWriter
