本文介绍如何使用C#编程语言通过StreamWriter和StreamReader类来创建、写入和读取简单的文本文件，包括文件的基本操作如打开、关闭、写入文本内容和逐行读取。

using System.IO;

private void btnWrite_Click(object sender, EventArgs e)
{
	using (StreamWriter pStreamWriter = new StreamWriter(@"d:\test.txt"))
	{
		pStreamWriter.WriteLine("----------------Title----------------");
		pStreamWriter.WriteLine("Content");
		pStreamWriter.WriteLine("----------------End------------------");
		pStreamWriter.Close();
	}
}

private void btnRead_Click(object sender, EventArgs e)
{
	using (StreamReader pStreamReader = new StreamReader(@"d:\test.txt"))
	{
		string line = "";
		while (pStreamReader.Peek() >= 0)
		{
			line = pStreamReader.ReadLine();
		}
	}
}

private void btnAppend_Click(object sender, EventArgs e)
{
	using (StreamWriter pStreamWriter = File.AppendText(@"d:\test.txt"))
	{
		pStreamWriter.WriteLine("Content01");
		pStreamWriter.WriteLine("Content02");
	}
}
