示例1: WriteIsolatedStorage
//引入命名空间
using System;
using System.Security.Permissions;
using System.IO.IsolatedStorage;
using System.IO;
// Notify the CLR to only grant IsolatedStorageFilePermission to called methods.
// This restricts the called methods to working only with storage files that are isolated
// by user and assembly.
[IsolatedStorageFilePermission(SecurityAction.PermitOnly, UsageAllowed = IsolatedStorageContainment.AssemblyIsolationByUser)]
public sealed class App
{
static void Main()
{
WriteIsolatedStorage();
}
private static void WriteIsolatedStorage()
{
// Attempt to create a storage file that is isolated by user and assembly.
// IsolatedStorageFilePermission granted to the attribute at the top of this file
// allows CLR to load this assembly and execution of this statement.
using (Stream s = new IsolatedStorageFileStream("AssemblyData", FileMode.Create, IsolatedStorageFile.GetUserStoreForAssembly()))
{
// Write some data out to the isolated file.
using (StreamWriter sw = new StreamWriter(s))
{
sw.Write("This is some test data.");
}
}
// Attempt to open the file that was previously created.
using (Stream s = new IsolatedStorageFileStream("AssemblyData", FileMode.Open, IsolatedStorageFile.GetUserStoreForAssembly()))
{
// Read the data from the file and display it.
using (StreamReader sr = new StreamReader(s))
{
Console.WriteLine(sr.ReadLine());
}
}
}
}输出：
Some test data.
