win8 app 创建文件夹目录
一、在winrt里面创建一个指定的文件夹目录不太好弄呀。自己写一个吧。有更好的写法请多多指教我。
代码部分：
///
/// 在winrt隔离存储区创建目录
///
public class ApplicationDataDirectory
{
///
/// 临时文件夹变量
///
private static StorageFolder _TempFolder;
///
/// 创建Winrt目录
///
/// 目录[格式如 @"\a\b\c\d"]
async public static Task CreateDirectory(string directory)
{
StorageFolder localFolder = ApplicationData.Current.LocalFolder;
//每个文件夹的名称
string[] folders = directory.Split(new string[] { @"\" }, StringSplitOptions.RemoveEmptyEntries);
Queue folderList = new Queue();
//将文件夹名放入一个集合中
for (int i = 0; i < folders.Length; i++)
{
folderList.Enqueue(folders);
}
//创建第一个文件夹
_TempFolder = await CreateFolder(localFolder, folderList.Peek());
//此时将刚才已经创建的文件夹名移除
folderList.Dequeue();
//如果下面还有文件夹要创建
if (folderList.Count >= 1)
{
//循环创建
foreach (var folderName in folderList)
{
_TempFolder = await CreateFolder(_TempFolder, folderName);
}
}
}
///
/// 在指定的文件夹下创建子文件夹
///
/// 指定的文件夹
/// 子文件夹名称
///
async private static Task CreateFolder(StorageFolder parentFolder, string childFolderName)
{
//在指定的文件夹中创建子文件夹
return await parentFolder.CreateFolderAsync(childFolderName, CreationCollisionOption.OpenIfExists);
}
}
比如我在 win8 metro 的隔离存储区创建一个文件目录\a\b\c\d
此时的调用方法为：
string path = @"\a\b\c\d";
await ApplicationDataDirectory.CreateDirectory(path);
二、上面写的太垃圾了，再修改下吧。
async private void btnCreateDirectory(object sender, RoutedEventArgs args)
{
string directory = @"\a\b\c\d";
await CreateFolder(directory);
}
async private Task CreateFolder(string directory)
{
StorageFolder tempStorageFolder=null;
string[] folders = directory.Split(new string[] { @"\" }, StringSplitOptions.RemoveEmptyEntries);
Queue _FolderList = new Queue();
for (int i = 0; i < folders.Length; i++)
{
_FolderList.Enqueue(folders);
}
tempStorageFolder = ApplicationData.Current.LocalFolder;
while (_FolderList.Count >= 1)
{
tempStorageFolder = await tempStorageFolder.CreateFolderAsync(_FolderList.Dequeue(), CreationCollisionOption.OpenIfExists);
}
}
欢迎有更好的写法!~
