This question already has an answer here:
I've modified my Settings.settings file in order to have system_Filters be a System.String[].
I would like to populate this variable within the Visual Studio designer and not from within the code. I can get it to work within the code using the following:
Properties.Settings.Default.system_Filters = new string[] { "a", "b", "c" };
string _systemFilters = Properties.Settings.Default.system_Filters;
This works correctly. However, I don't have a nice place to put this in my code and ideally want to type it in the Settings.setting file. This value will not be modified. I've tried almost every variant I can think of, but the result is always the same.
Does anyone know the correct syntax? I'm also open to using a StringCollection if that's easier.
Try to use StringCollection instead of string[]. It is natively supported by the settings designer.
The value is stored as XML, but you don't need to edit it manually. When you select StringCollection in the Type column, the editor in the Value column changes; there is a ... button, which opens a dialog to type the strings.
