private boid button_Click(object sender,System.Windows.RotedEventArgs e){
if(this.textbox.Text=="" || this.passwordbox.Password==""){
MessageBox.Show("缺少输入信息");
}
IsolatedStorageFileStream isoStore=new IsolatedStorageFileStream("myinfo.txt",FileMode.Create,IsolatedStorageFile.GetUserStoreForApplication());
StreamWriter wtxt=new StreamWriter(isoStore);
wtxt.WriteLine(this.textbox.Text.Trim());
wtxt.WriteLine(this.passwordbox.Password.Trim());
wtxt.Close();
isoStore.Close();
MessageBox.Show("独立存储吸入myinfo.txt完成！");
}
