处理txt文件的数据
我想实现如下功能，点击一个转换按钮将打开的一个文本文件的数据进行处理。原文件是
姓名   年龄   性别  
  1，   2，       女
  3，4，         男
处理后显示
  1   女
  3   男
没有思路，不知道该如何下手，请教大家了

int size=(int)fs.Length;
byte[] buff = new byte[size];
fs.Read(buff, 0, size);
fs.Close();

System.Text.Encoding en= System.Text.Encoding.GetEncoding(@ "GB2312 ");
string s = en.GetString(buff, 0, size);

System.IO.StringReader sr= new System.IO.StringReader(s);

string[] separator = new string[2];
separator[0] = @ ", ";
separator[1] = @ "， ";

string data;
data = sr.ReadLine();

while (data != null)
{
string[] d = data.Split(separator, StringSplitOptions.None);
string item = d[0].Trim() + @ " " + d[2].Trim();
listBox1.Items.Add(item);

data = sr.ReadLine();
}

}
}
}

给你一人简单参考

FileStream fs = new FileStream(textBox1.Text, FileMode.Open, FileAccess.Read);
fs.Seek(0, SeekOrigin.Begin);
FileStream fs2 = new FileStream(textBox1.Text + "1 ", FileMode.Create, FileAccess.Write);
fs2.Seek(0, SeekOrigin.Begin);
int i = 0;
StreamReader sr = new StreamReader(fs);
StreamWriter sw = new StreamWriter(fs2);
try
{
string Line1 = null;
string Line2 = null;
string Temp = null;

while (true)
{
Line1 = sr.ReadLine();
if (Line1.IndexOf( "point1 = new Point ") > 0)
{
Line2 = sr.ReadLine();
i = Line1.IndexOf( "new Point ");
Temp = Line1.Substring(i, Line1.Length - i - 1);
Line2 = Line2.Replace( "point1 ", Temp);
sw.WriteLine(Line2);
}
else if (Line1.IndexOf( "size1 = new Size ") > 0)
{
Line2 = sr.ReadLine();
i = Line1.IndexOf( "new Size ");
Temp = Line1.Substring(i, Line1.Length - i - 1);
Line2 = Line2.Replace( "size1 ", Temp);
sw.WriteLine(Line2);
}
else if (Line1 == "this end ")
