Question

This is an offline app And I am simply trying to write back to to the Settings.settings file.

In my project under Properties in the file named Settings.settings I add

Name: User, Type: string, Scope:User, Value:Default

After that in my App.xaml.cs file I attempt to read from and write to that value. I have no issue reading from that value, but it seems that it is not even an option to write back.

Here is my code:

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Windows;

namespace StrainTracker
{
    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application
    {
        string userName= StrainTracker.Properties.Settings.Default.User;
        StrainTracker.Properties.Settings.Default.User = "SomethingSilly"; //line 16
        StrainTracker.Properties.Settings.Default.Save();                  //line 17
    }
}

Here are the errors generated by visual studio.

Error   1   Invalid token '=' in class, struct, or interface member declaration ..\Projects\StrainTracker\StrainTracker\App.xaml.cs 16  63  StrainTracker
Error   2   Invalid token '(' in class, struct, or interface member declaration ..\Projects\StrainTracker\StrainTracker\App.xaml.cs 17  55  StrainTracker
Error   3   'StrainTracker.Properties.Settings.Default' is a 'property' but is used like a 'type'   ..\Projects\StrainTracker\StrainTracker\App.xaml.cs 16  43  StrainTracker
Error   4   'StrainTracker.Properties.Settings.Default' is a 'property' but is used like a 'type'   ..\Projects\StrainTracker\StrainTracker\App.xaml.cs 17  43  StrainTracker

I can not for the life of me figure out what the issue is. Any thoughts?

Consider placing the code inside a constructor or some method:

public partial class App : Application 
{
    public App()
    { 
        string userName= StrainTracker.Properties.Settings.Default.User;
        StrainTracker.Properties.Settings.Default.User = "SomethingSilly";
        StrainTracker.Properties.Settings.Default.Save();
    }
}
