请指点一二．．．

using System;
using System.IO;
class A
{
public static void Main(string[] args)
{
      FileStream fs = new FileStream(@"f:\test.txt", FileMode.Open, FileAccess.Read);
      StreamReader sr = new StreamReader(fs);
      sr.BaseStream.Seek(0, SeekOrigin.Begin);
      string str1 = sr.ReadLine();
      string[] str2=new string[10];
      int x;
      int Count = 0;
      while (str1 != null)
      {
         str1 = sr.ReadLine();
         x = str1.IndexOf("T");
         str2[Count] = str1.Substring(x, 3);
         Count++;
      }

      for (int i = 0; i < Count;i++ )
      {
         Console.WriteLine(str2[i]);
      }
}
}
这段代码为什么不能输出＇str2＇？？？？？
帮忙修改一下．．．

         Console.WriteLine(str2[i]);
      }

}
}
