我需要获取给定 IsolatedStorage 文件夹中所有文件的列表。 IsolatedStorage 的根目录之外有子文件夹,这些需要包含在列表中。
通常的 System.IO 类不能与 IsolatedStorage 一起使用。
最佳答案
这是我想出的 - 它有效,但我很想看看是否有更好的选择:
using System.Collections.Generic;
using System.IO;
using System.IO.IsolatedStorage;
using System.Linq;
public static class IsolatedStorageFileExtensions
{
/// <summary>
/// Recursively gets a list of all files in isolated storage
/// </summary>
/// <remarks>Based on <see cref="http://dotnetperls.com/recursively-find-files"/></remarks>
/// <param name="isolatedStorageFile"></param>
/// <returns></returns>
public static List<string> GetAllFilePaths(this IsolatedStorageFile isolatedStorageFile)
{
// Store results in the file results list
List<string> result = new List<string>();
// Store a stack of our directories
Stack<string> stack = new Stack<string>();
// Add initial directory
string initialDirectory = "*";
stack.Push(initialDirectory);
// Continue while there are directories to process
while (stack.Count > 0)
{
// Get top directory
string dir = stack.Pop();
string directoryPath;
if (dir == "*")
{
directoryPath = "*";
}
else
{
directoryPath = dir + @"\*";
}
// Add all files at this directory to the result List
var filesInCurrentDirectory = isolatedStorageFile.GetFileNames(directoryPath).ToList<string>();
List<string> filesInCurrentDirectoryWithFolderName = new List<string>();
// Prefix the filename with the directory name
foreach (string file in filesInCurrentDirectory)
{
filesInCurrentDirectoryWithFolderName.Add(Path.Combine(dir, file));
}
result.AddRange(filesInCurrentDirectoryWithFolderName);
// Add all directories at this directory
foreach (string directoryName in isolatedStorageFile.GetDirectoryNames(directoryPath))
{
stack.Push(directoryName);
}
}
return result;
}
}
关于c# - 您如何获得 IsolatedStorage 中所有文件的平面列表?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/3038770/
