在WM6上查找存储卡路径 [英] Finding the storage card path on WM6

问题描述

是否有一种简单的方法可以在 Windows Mobile 设备上找到存储卡的路径当有存储卡和蓝牙 ftp 连接时?

Is there an easy way to find the storage card's path on a Windows Mobile device when there is a storage card and a bluetooth ftp connection?

推荐答案

请记住，\Storage Card"是面向英语的.为不同地区制造的设备可能有不同的名称.我设备上存储卡路径的名称因我使用设备的方式而异.

Keep in mind that "\Storage Card" is english oriented. A device made for a different region may have a different name. The name of the storage card path on my device varies with how I am using the device.

前段时间在MSDN的表格里回答了几个关于如何检测文件系统中的存储卡以及如何获取存储卡容量的问题.我写了以下可能是对这些问题的回应，并认为分享会有所帮助.存储卡在文件系统中显示为临时目录.该程序检查设备根目录中的对象，任何具有临时属性的文件夹都被认为是正匹配

Some time ago in the MSDN forms I responded to a few questions on how to detect the storage cards in the file system and how does one get the storage card's capacity. I wrote the following could are a response to those questions and thought it would be helpful to share. Storage cards show up in the file system as temporary directories. This program examines the objects in the root of the device and any folders that have temp attribute are considered to be a positive match

using System;
using System.IO;
using System.Runtime.InteropServices;

namespace StorageCardInfo
{
    class Program
    {
        const ulong Megabyte = 1048576;
        const ulong Gigabyte = 1073741824;

        [DllImport("CoreDLL")]
        static extern int GetDiskFreeSpaceEx(
        string DirectoryName,
        out ulong lpFreeBytesAvailableToCaller,
        out ulong lpTotalNumberOfBytes,
        out ulong lpTotalNumberOfFreeBytes 
    );

    static void Main(string[] args)
    {
        DirectoryInfo root = new DirectoryInfo("\\");
        DirectoryInfo[] directoryList = root.GetDirectories();
        ulong FreeBytesAvailable;
        ulong TotalCapacity;
        ulong TotalFreeBytes;

        for (int i = 0; i < directoryList.Length; ++i)
        {
            if ((directoryList.Attributes & FileAttributes.Temporary) != 0)
            {
                GetDiskFreeSpaceEx(directoryList.FullName, out FreeBytesAvailable, out TotalCapacity, out TotalFreeBytes);
                Console.Out.WriteLine("Storage card name: {0}", directoryList.FullName);
                Console.Out.WriteLine("Available Bytes : {0}", FreeBytesAvailable);
                Console.Out.WriteLine("Total Capacity : {0}", TotalCapacity);
                Console.Out.WriteLine("Total Free Bytes : {0}", TotalFreeBytes);
            }
        }
    }
}
