C# How to loop through Properties.Settings.Default.Properties changing the values

Question

I have the following code:

foreach (SettingsProperty currentProperty in Properties.Settings.Default.Properties)
{
    if (Double.TryParse(GenerateValue()), out result))
    {
        currentProperty.DefaultValue = result.ToString();

        Properties.Settings.Default.Save();
    }
}

It gets the new value from a mysql database. If I add a MessageBox.Show to show the new value it seems to be working fine but it doesn't actually save it. I assume this is because I am assigning the value to a variable...is there some way to do this?

Properties.Settings.Default.IndexOf(currentProperty.name).DefaultValue = result

This might work:

foreach (SettingsProperty  currentProperty in Properties.Settings.Default.Properties)
{
    Properties.Settings.Default[currentProperty.Name] = result.ToString();
    Properties.Settings.Default.Save();
}

Keep in mind that properties should have scope 'User' in order to be saved.

I knew there had to be a way to do it. Thanks a lot for your help. I did have everything set to User already as well. – Brandon May 03 '11 at 17:22
[Alex Azabut] how do I find the scope of the setting? – gg89 Aug 30 '16 at 21:09
I suspect I can use !setting.ReadOnly as user scope, right? – gg89 Sep 01 '16 at 05:56

I would agree with your conclusion. What you are going have to do is get the property by the string value.

Properties.Settings.Default[string value] =

    foreach (SettingsProperty currentProperty in Properties.Settings.Default.Properties) 
    {    
    if (Double.TryParse(GenerateValue()), out result))  
       {        

Properties.Settings.Default[ currentProperty.Name ] = result.ToString();
          Properties.Settings.Default.Save(); 
        } 
    }

The above is what you actually want.

My answer would actually compile. *Hint**Hint**Hint* – Security Hound May 03 '11 at 17:27 — Security Hound, May 03 '11 at 17:27

I wanted to be retrieve the settings and save them back on program startup so that the entire settings file would be editable in appData. This is what I call when starting the program:

            foreach (SettingsProperty currentProperty in Settings.Default.Properties)
            {
                var value = Settings.Default[currentProperty.Name];
                Settings.Default[currentProperty.Name] = value;
                Settings.Default.Save();
            }

This seems to work regardless of the type of setting.
