Visual Studio 2010文件权限

有一个小程序，它应该打开文件，然后输出到控制台添加行号。问题是，无论程序是从命令控制台还是从IDE运行，它都会抛出关于文件权限的异常。

我将可执行文件和应该被读取的文件(简单的TXT文件)移动到几个目录(我的文档，temp等)以Admin身份运行console，以Admin身份运行Visual studio，给两个文件所有权限，但它总是抛出异常。最奇怪的是，一两个星期前，我通过试错找到了解决方案，但我不记得了。

这里有一个例外:

    Exception: System.UnauthorizedAccessException: Access to the path 'C:'Users'Nena
d'documents'visual studio 2010'Projects'Listing 10.6'Listing 10.6'bin'Debug'prog

代码如下:

// ListFile.cs - program to print a listing to the console
//-----------------------------------------------------------
using System;
using System.IO;
class ListFile
{
    public static void Main(string[] args)
    {
        try
        {
            int ctr = 0;
            if (args.Length <= 0)
            {
                Console.WriteLine("Format: ListFile filename");
                return;
            }
            else
            {
                FileStream fstr = new FileStream(args[0], FileMode.Open);
                try
                {
                    StreamReader t = new StreamReader(fstr);
                    string line;
                    while ((line = t.ReadLine()) != null)
                    {
                        ctr++;
                        Console.WriteLine("{0}:  {1}", ctr, line);
                    }
                }
                catch (Exception e)
                {
                    Console.WriteLine("Exception during read/write: {0}'n", e);
                }
                finally
                {
                    fstr.Close();
                }
            }
        }
        catch (System.IO.FileNotFoundException)
        {
            Console.WriteLine("ListFile could not find the file {0}", args[0]);
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception: {0}'n'n", e);
        }
    }
