C#无法在流的结尾之外进行读取

[SeasonRun]

public void Reading()
{
if (File.Exists("C:\\IPChange.txt"))
{
FileStream fs =new FileStream("C:\\IPChange.txt", FileMode.Open,FileAccess.Read,FileShare.Read);
BinaryReader reader = new BinaryReader(fs);
text11.Text = reader.ReadString();
text12.Text = reader.ReadString();
text13.Text = reader.ReadString();
text14.Text = reader.ReadString();
text15.Text = reader.ReadString();
text21.Text = reader.ReadString();
text22.Text= reader.ReadString();
text23.Text = reader.ReadString();
text24.Text = reader.ReadString();
text25.Text = reader.ReadString();
reader.Close();
fs.Close();
}
}运行提醒无法在流的结尾之外进行读取，什么意思啊，要怎么解决，请大家帮忙解决，谢谢！

那要怎么解决呢？

搞错对象了 - -
不过这个BinaryReader.ReadString()的方法不能正常使用，我测试的时候，第一次读取就异常了，此时_Position=0,_Length=23建议使用StreamReader
[code=C#]

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using System.IO;
using System.Text;

namespace test
{
public partial class test :TestPageBase
{
public class MyReader : BinaryReader
{
public MyReader(Stream stream):base(stream)
{

}
public MyReader(Stream stream, Encoding code)
: base(stream, code)
{
}
private long _Length = -1;
private long _Position = -1;
public override string ReadString()
{
if (_Length < 0)
{ _Length = BaseStream.Length; }
_Position = BaseStream.Position;
if (_Position < _Length)
return base.ReadString();
else
return "";
}
}
protected void Page_Load(object sender, EventArgs e)
{
//FileStream file = File.OpenRead(@"D:\Test");
//if (file.CanRead)
//{
// MyReader br = new MyReader(file, Encoding.UTF8);
// string str = "InitData";
// while (!string.IsNullOrEmpty(str))
// {
// str = br.ReadString();
// Say(str);
// }
//}
StreamReader sr = new StreamReader(@"D:\Test");
while (!sr.EndOfStream)
{
Say(sr.ReadLine());
}
}

}
}

你的位置已经超出了流的范围，比如流就有10个字节，你非得去读第20个字节
