How to initialize StringDictionary in my project settings

Question

I've added a StringDictionary to my project settings in VS2010. When I try to add members to it in my program, I get a NullReferenceException. When I try to initialize a value in its Value column in my project settings, it says my entry cannot be converted to StringDictionary. I'm sure it's looking for some XML code, but isn't there a better way to initialize the StringDictionary before compilation?

Additional info:

1. Go to Menu -> Project -> [Project Name]> Properties... -> Settings

2. Add a setting named mySetting of type System.Collections.Specialized.StringDictionary

3. In your code add a line [ProjectName].Properties.Settings.Default.mySetting.Add("key","value");

4. Run and get the exception.

Answer 1

I ended up just using two ArrayList settings in place of the one Hashtable setting.
