代码如下
using System;
using System.Collections.Generic;
using System.Linq;
using
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using
using System.Text;
namespace one
{
    public partial class MainPage : PhoneApplicationPage
    { // Constructor
        public MainPage()
        {
            InitializeComponent();
           
            Test();
            ……………………
         }

        public void Test()
        {
            string path = @"路径";
            FileInfo fi = new FileInfo(strpath);
             fs = fi.OpenRead();
            byte[] bInfo = new byte[44];
            fs.Read(bInfo, 0, 44);
            ……………………
        }
}
运行时，fs为null，提示错误Attempt to access the method failed: (System.String)，本人初学啊，菜鸟一枚，请高手支招，谢谢啦
