如何一次性删除文件和应用程序数据容器值?

How to Delete Files and Application Data Container Values in One Go?(如何一次性删除文件和应用程序数据容器值?)

问题描述

我的应用中有一个重置功能，可以将应用恢复到默认状态.在那里我需要删除我创建的四个文件并删除我在 ApplicationDataContainer 中创建的设置.这就是我删除文件的方式

I have a reset function in my app which brings the app back to default state. There for I need to remove the four files I created and remove the settings I created in the ApplicationDataContainer. This is how I remove the files

try
{
    StorageFile file = await localfolder.GetFileAsync("HistoryFile");
    if (file != null)
    {
        await file.DeleteAsync();
    }
}
catch
{
    //Catch Process
}

有没有一起删除所有文件的功能?当我尝试以下代码时

Is there a function which removes all the files together? When I tried the following code

localfolder.DeleteAsync()

它连同文件一起删除了 LocalState 文件夹，我只需要删除文件而不是文件夹.

It removed the LocalState folder along with the files, I jus need to remove the files not the folder.

无论如何，我可以一次性删除 ApplicationDatacontainer 中存储的所有值吗?而不是像这样一一删除?

And is there anyway in which I jus can remove all the values stored in ApplicationDatacontainer in one go? rather than removing them one by one like this?

localSettings.DeleteContainer("exampleContainer");

推荐答案

如果你想从本地数据存储中删除应用程序数据，试试这个.

If you want to remove application data from its local data store, try this.

await Windows.Storage.ApplicationData.Current.ClearAsync(
     Windows.Storage.ApplicationDataLocality.Local);
