Why am I unable to select a custom Type for a sett

Question

I am trying to set the type of an application setting property to a custom enum type I have defined in my assembly (call this Project A)

In the settings browser I click browse and am presented with the "Select a Type" dialog box.

And the Types defined in Project A are not seem to be available to me. Yet types are available from other projects that A has referenced.

It seems almost beyond comprehension to me that one would not be able to use Types defined in the base project, so I assume I am doing something wrong. I have tried building, cleaning, rebuilding, restarting without any luck, so what exactly am I missing?

Answer 1

I was trying the same and the solution was very simple: Build first.

I added an enum class, defined some values and then tried to replace an int-value in the Settings.settings file with my new enum, so I don't have to match the value later. The type was not found. Because I did not build yet.

After Building once the new enum type is known and can be used :)

Answer 2

I could not browse to my custom type either. I was able to add my custom type by opening the Settings.settings file in a text editor and adding the setting to the Settings section like this:

<Setting Name="Options" Type="MyProject.MyOptions" Scope="User">
  <Value Profile="(Default)" />
</Setting>

The settings designer complains when I open it, but I just respond 'No' to that dialog, and I am able to use the custom setting in my project.

Because your own type is not serializable. Make it serializable and you can define it in your settings.

Answer 4

I was trying to do exactly the same thing in VS 2010 (.net 3.5). It turns out that you can do this using the Settings designer. The UI is totally flawed, as stated, but if you manually enter the fully qualified name of the enum in the Browse window it'll work. This has the benefit of not modifying generated code (*.Designer.cs), which is always good to avoid because when you do there's no guarantee that you're changes won't be overwritten.

PS - This only seems to work if the enum is public.

Settings GUI:

Then manually type fully-qualified type name:

At one point I swear I saw a drop-down of the enum values in the Value column, but I haven't seen it since and you just have to type an appropriate value in.
