こんにちは、フォルダーを削除した後にバインドされているリストボックスを更新しようとしていますが、ページから出て戻るまで更新されないようです。
public partial class Page3 : PhoneApplicationPage
{
string[] fileNames;
string[] folderNames;
private string selectedProject = "";
private List<Project> projectList = new List<Project>();
public Page3()
{
InitializeComponent();
showProjects();
}
public void showProjects()
{
projectList.Clear();
IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication();
folderNames = isf.GetDirectoryNames("/*.*");
foreach (var name in folderNames)
{
fileNames = isf.GetFileNames(name + "/*.*");
int frameCount = 0;
foreach (var nameCount in fileNames)
{
frameCount++;
}
projectList.Add(new Project(name,frameCount));
}
listBoxProjects.ItemsSource = projectList;
}
private void listBoxProjects_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
}
public void DeleteDirectory(string directoryName)
{
try
{
IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
if (!string.IsNullOrEmpty(directoryName) && myIsolatedStorage.DirectoryExists(directoryName))
{
myIsolatedStorage.DeleteDirectory(directoryName);
}
}
catch (Exception ex)
{
// handle the exception
}
}
private void button1_Click(object sender, RoutedEventArgs e)
{
IsolatedStorageFile myIso;
string folder = textBoxDelete.Text;
using (myIso = IsolatedStorageFile.GetUserStoreForApplication())
{
String[] fileNames = myIso.GetFileNames(folder + "/*.*");
foreach (var name in fileNames)
{
MessageBox.Show(name);
myIso.DeleteFile(folder + "/" + name);
}
myIso.DeleteDirectory(folder);
showProjects();
}
}
}
public class Project

public Project(string pName, int fileCount)
