Mike Snow demonstrated how to read file and load file from local storage. Please read the C# for details.
Save and read file from local storage:
using System;
using System.Windows.Controls;
using System.IO.IsolatedStorage;
using System.IO;
namespace SilverlightApplication10
{
public class Page : UserControl
{
public Page()
{
SaveData("Hello There", "MyData.txt");
if (HasFile("MyData.txt"))
{
string test = LoadData("MyData.txt");
}
}
private void SaveData(string data, string fileName)
{
IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isfs = new IsolatedStorageFileStream(fileName, FileMode.Create, isf);
using (StreamWriter sw = new StreamWriter(isfs))
{
sw.Write(data);
sw.Close();
}
}
private bool HasFile(string fileName)
{
IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication();
return isf.FileExists(fileName);
}
private string LoadData(string fileName)
{
string data = String.Empty;
IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isfs = new IsolatedStorageFileStream(fileName, FileMode.Open, isf);
using (StreamReader sr = new StreamReader(isfs))
{
string lineOfData = String.Empty;
while ((lineOfData = sr.ReadLine()) != null) data += lineOfData;
}
return data;
}
}
}
