In Word - How to find all occurrences of a regex between square brackets? : I'm opening a word doc using `Microsoft.Office.Interop.Word` 

    word.Application wordApp = new word.Application { Visible = true };
                word.Document aDoc = wordApp.Documents.Open(fileName, ReadOnly: false, Visible: true);
                aDoc.Activate();


What I want to do is find all text that is between `[]` for example `[Fruit]` or `[Pears]`


So this is a two part question

 - How do you find all text in a word doc between []
 - What is the appropriate regex for anything between square brackets []
