Hi...
I am developing an app in windows mobile 7 in which I need to read a text file. I wrote a code for that but when I debug that code, it gives an error "method access exception". Same code is working in C# windows form app.
I dont know what is the problem. Please suggest me for this and solve this problem. My code is like this:

namespace fileread
{
    public partial class MainPage : PhoneApplicationPage
    {

        private string line;

        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            StreamReader sr = new StreamReader(@"D:\abc.txt");
            line = sr.ReadLine();
            MessageBox.Show(line);
        }

在行上发生错误:"line = sr.ReadLine();"

Error occured at line: "line = sr.ReadLine();"

推荐答案

由于Windows vista的安全性，根目录是受保护的区域.这很可悲，但这是Windows中的保护级别.但这只是设计使然".

祝你好运！

The root directory is a protected area since windows vista for security. It''s pathetic, but this is the level of protection in windows. But this is simply "by design".

Good luck!
