IStorageItem2 IStorageItem2 IStorageItem2 IStorageItem2 Interface

Gets the parent folder of the current storage item.

public : IAsyncOperation<StorageFolder> GetParentAsync()public IAsyncOperation<StorageFolder> GetParentAsync()Public Function GetParentAsync() As IAsyncOperation( Of StorageFolder )// You can use this method in JavaScript.

Remarks

You must have access to the parent for the GetParentAsync method to succeed, either by declaring library capabilities or by persisting a higher-level folder in the Access List. Also, this method returns null if you can’t get to the parent, instead of raising an exception.

This example shows how to get the parent folder of a StorageFile.

function openParentFolder(file) {
    file.GetParentAsync().done(function (folder) {
        if (folder != null) {
            folder.getItemsAsync(function (items) {
                var list = document.getElementById("parentFolderItemsList");
                items.forEach(function (item) {
                    var listItemElement = document.createElement("li");
                    if (item.isOfType(Windows.Storage.StorageItemTypes.folder)) {
                        listItemElement.textContent = item.name + "\\";
                    } else {
                        listItemElement.textContent = item.name;
                    }
                    list.appendChild(listItemElement);
                });
            });
        } else {
            // Unable to get parent folder
        }
    });
}

Indicates whether the current item is the same as the specified item.

public : PlatForm::Boolean IsEqual(IStorageItem item)public bool IsEqual(IStorageItem item)Public Function IsEqual(item As IStorageItem) As bool// You can use this method in JavaScript.

Remarks

Use the IsEqual method to determine whether two storage items represent the same file or folder.

This method compares the Path property of both items to determine if they are the same. If there is no Path (if the item is a library for example), or if the paths do not match the items are compared using IShellItem::Compare.

This example shows how to compare two storage files for equality.

function openNewFile() {
    var picker = new Windows.Storage.Pickers.FileOpenPicker;
    picker.fileTypeFilter.replaceAll(["*"]);
    picker.pickSingleFileAsync().then(function (file) {
        var alreadyOpenedFile = null;
        _openFiles.some(function (openFile) {
            if (file.IsEqual(openFile.file)) {
                alreadyOpenedFile = openFile;
                return true;
            }
            return false;
        });

        if (alreadyOpenedFile != null) {
            alreadyOpenedFile.window.activate();
        } else {
            createNewFileViewerWindow(file);
        }
    });
}
