在WP7和8上递归删除隔离存储中目录的简单方法

由于API不支持递归删除,因此您将不得不自己进行删除。比如。

public static void DeleteDirectoryRecursively(this IsolatedStorageFile storageFile, String dirName)
{
    String pattern = dirName + @"\*";
    String[] files = storageFile.GetFileNames(pattern);
    foreach (var fName in files)
    {
        storageFile.DeleteFile(Path.Combine(dirName, fName));
    }
    String[] dirs = storageFile.GetDirectoryNames(pattern);
    foreach (var dName in dirs)
    {
        DeleteDirectoryRecursively(storageFile, Path.Combine(dirName, dName));
    }
    storageFile.DeleteDirectory(dirName);
}

用户存储有一个方法Clear(),它可以清理整个东西

using (var userStore = IsolatedStorageFile.GetUserStoreForApplication())
{
    userStore.Clear();
}

请记住,这会删除所有内容,甚至是配置
