Question

我正试图对孤立的储存进行检查,随后有一些指挥部也这样做。

What i wanted was to check for directories name consisting "a*" *If the directories exist* it will check if the diretory named after "a + today date" exist.

如果exist将显示的电文,该电文确实存在。

But if no directories consisting of "a*" is exist at all it will show a message of "Does not exist".

我的法典如下:

Is able to check if the directories exist when there is a directory of "a*" is created.
But it does not work *when none of the directories "a" is created**. How should i modify my code?

法典:

string[] fileNames;
string selectedFolderName;

private void gameBtn_Click(object sender, RoutedEventArgs e)
{
    //MediaPlayer.Stop();

    string currentDate = DateTime.Now.ToString("MMddyyyy");
    string currentDateName = "a" + currentDate;


    IsolatedStorageFile myStore = IsolatedStorageFile.GetUserStoreForApplication();

        fileNames = myStore.GetDirectoryNames("a*");

        foreach (var name in fileNames)
        {
            if (fileNames.Contains(currentDateName))
            {
                selectedFolderName = currentDateName;
                MessageBox.Show("Your schedule for today");
                NavigationService.Navigate(new Uri("/DisplaySchedule.xaml?selectedFolderName=" + selectedFolderName, UriKind.Relative));
            iii
            else
            {
                MessageBox.Show("No Schdule for today", "Schedule Reminder", MessageBoxButton.OK);
                NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.Relative));

Answer 1

你的错误只是一个简单的字体。

if (fileNames.Contains(currentDateName))

应当

if (name.Contains(currentDateName))

关于在没有名录“a*”时的处理,如果<代码>Names,则检查是空的。

if (fileNames.Length == 0) // no Directory  a  was found, create it
{
     // create code here
}
