【问题描述】:
我目前正在创建一个 windows phone 7 应用程序。如何将数组的所有值转换为文本文件,以便我可以打印出存储在另一个页面列表框内的特定数组中的所有值,然后存储在隔离存储中。 谢谢! :(
我试过这个方法,但它不起作用。 对于 ViewList.xaml.cs
private void addListBtn_Click(object sender, RoutedEventArgs e)
{
//Obtain the virtual store for application
IsolatedStorageFile myStore = IsolatedStorageFile.GetUserStoreForApplication();
//Create a new folder and call it "ImageFolder"
myStore.CreateDirectory("ListFolder");
//Create a new file and assign a StreamWriter to the store and this new file (myFile.txt)
//Also take the text contents from the txtWrite control and write it to myFile.txt
StreamWriter writeFile = new StreamWriter(new IsolatedStorageFileStream("ListFolder\\myFile.txt", FileMode.OpenOrCreate, myStore));
writeFile.WriteLine(retrieveDrinksListBox);
writeFile.Close();
}
FavoriteList.xaml.cs
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
//Obtain a virtual store for application
IsolatedStorageFile myStore = IsolatedStorageFile.GetUserStoreForApplication();
//This code will open and read the contents of retrieveDrinksListBox
//Add exception in case the user attempts to click “Read button first.
StreamReader readFile = null;
try
{
readFile = new StreamReader(new IsolatedStorageFileStream("ListFolder\\myFile.txt", FileMode.Open, myStore));
string fileText = readFile.ReadLine();
if (fileText != "")
{
listNumberListBox.Items.Add("List 1");
}
//The control txtRead will display the text entered in the file
listNumberListBox.Items.Add(fileText);
readFile.Close();
}
catch
{
MessageBox.Show("Need to create directory and the file first.");
}
