private const string foldername = "temp1";
private const string filename = foldername + "/address.txt";
private const string settingname = "sname";
1.创建文件夹
private void button1_Click(object sender, RoutedEventArgs e)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
file.CreateDirectory(foldername);
}
}
2.检查文件夹是否存在
private void button2_Click(object sender, RoutedEventArgs e)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
if (file.DirectoryExists(foldername))
{
MessageBox.Show("已存在");
}
else
{
MessageBox.Show("不存在");
}
}
}
3.删除目录
private void button3_Click(object sender, RoutedEventArgs e)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
file.DeleteDirectory(foldername);
}
}
4.创建文件
private void button4_Click(object sender, RoutedEventArgs e)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
IsolatedStorageFileStream stream = file.CreateFile(filename);
stream.Close();
}
}
5.检查文件是否存在
private void button5_Click(object sender, RoutedEventArgs e)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
if (file.FileExists(filename))
{
MessageBox.Show("已存在" + filename);
}
else
{
MessageBox.Show("不存在");
}
}
}
6.删除文件
private void button6_Click(object sender, RoutedEventArgs e)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
file.DeleteFile(filename);
}
}
7.向文件中增加内容
private void button7_Click(object sender, RoutedEventArgs e)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream stream = file.OpenFile(filename, FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
StreamWriter writer = new StreamWriter(stream);
writer.WriteLine(textBox1.Text);
writer.Close();
textBox1.Text = "";
}
}
}
8.读取文件内容
private void button8_Click(object sender, RoutedEventArgs e)
{
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream stream = file.OpenFile(filename, FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
using (StreamReader reader=new StreamReader (stream))
{
textBox1.Text = reader.ReadToEnd();
}
} }
}
9、程序配置信息保存
private void button9_Click(object sender, RoutedEventArgs e)
{
IsolatedStorageSettings.ApplicationSettings[settingname] = textBox2.Text;
IsolatedStorageSettings.ApplicationSettings.Save();
textBox2.Text = "";
}
10.程序配置信息读取
private void button10_Click(object sender, RoutedEventArgs e)
{
if (IsolatedStorageSettings.ApplicationSettings.Contains(settingname))
{
textBox2.Text = IsolatedStorageSettings.ApplicationSettings[settingname].ToString();
}
}
