[Windows Store] 在Windows Store APP中使用Skydrive API操作資料夾(CRUD)

在上一篇介紹了Windows Store APP中使用Live SDK的登入，這篇就來看下Live SDK中關於Skydrive API的部分，以下就以操作Skydrive資料夾的新增、讀取、更新、刪除(CRUD)為範例:

 

介面部分很簡單就是放一個登入鈕跟Create、Get、Update、Delete(CRUD)四個按鈕，旁邊的Listbox則用來顯示讀取到的所有資料夾，而登入部分的程式碼可以參考上一篇文章，這裡就不再重複說明

新增資料夾

要成功新增資料夾，必須記得在登入時要跟使用者取得wl.skydrive_update的權限，程式碼如下:

	private async void CreateButton_Click(object sender, RoutedEventArgs e)
	{
	try
	{
	Dictionary<string, object> newfolder = new Dictionary<string, object>();
	newfolder.Add("name", "testfolder"); //testfolder是要建立的資料夾名稱
	LiveOperationResult operationresult = await liveClient.PostAsync("me/skydrive", newfolder);
	MessageDialog msg = new MessageDialog(string.Format("FolderName:{0}\nID:{1}",
	operationresult.Result["name"],
	operationresult.Result["id"]
	));
	await msg.ShowAsync();
	}
	catch (LiveConnectException ex)
	{
	MessageDialog msg = new MessageDialog(ex.Message);
	msg.ShowAsync();
	}
	}

讀取資料夾

讀取資料夾記得要取得wl.skydrive權限，這邊範例是取得所有的資料夾資訊並顯示在Listbox中，而把ID值記在Tag屬性中則是讓選中的資料夾可以做update跟delete，如果只是要取得某個資料夾只要在GetAsync()方法中傳入資料夾ID即可

	private async void GetButton_Click(object sender, RoutedEventArgs e)
	{
	try
	{
	LiveOperationResult operationResult = await liveClient.GetAsync("me/skydrive/files");
	List<object> data = (List<object>)operationResult.Result["data"];
	FolderBox.Items.Clear();
	foreach (dynamic item in data)
	{
	//將資料夾的ID記在Tag中方便做update和delete
	FolderBox.Items.Add(new ListBoxItem()
	{
	Content = item.name,
	Tag = item.id
	});
	}
	}
	catch (LiveConnectException ex)
	{
	MessageDialog msg = new MessageDialog(ex.Message);
	msg.ShowAsync();
	}
	}

在Listbox中顯示讀取的資料夾

 

更新資料夾

更新資料夾要wl.skydrive_update權限，此範例中會將Listbox中選中的資料夾更新名字，而需要傳入的ID就是剛剛記在Tag屬性中的值

	private async void UpdateButton_Click(object sender, RoutedEventArgs e)
	{
	try
	{
	if (FolderBox.SelectedItem != null)
	{
	Dictionary<string, object> updatefolder = new Dictionary<string, object>();
	updatefolder.Add("name", "updatefolder");
	//PutAsync中傳入要更新的資料夾ID
	LiveOperationResult operationresult = await liveClient.PutAsync((FolderBox.SelectedItem as ListBoxItem).Tag.ToString(), updatefolder);
	MessageDialog msg = new MessageDialog("Folder updated");
	await msg.ShowAsync();
	}
	}
	catch (LiveConnectException ex)
	{
	MessageDialog msg = new MessageDialog(ex.Message);
	msg.ShowAsync();
	}
	}

刪除資料夾

刪除資料夾要wl.skydrive_update權限，一樣也是刪除Listbox中選中的資料夾

	private async void DeleteButton_Click(object sender, RoutedEventArgs e)
	{
	try
	{
	if (FolderBox.SelectedItem != null)
	{
	//DeleteAsync中傳入要刪除的資料夾ID
	LiveOperationResult operationresult = await liveClient.DeleteAsync((FolderBox.SelectedItem as ListBoxItem).Tag.ToString());
	MessageDialog msg = new MessageDialog("Folder deleted");
	await msg.ShowAsync();
	}
	}
	catch (LiveConnectException ex)
	{
	MessageDialog msg = new MessageDialog(ex.Message);
	msg.ShowAsync();
	}
	}
