'can Dictionary<string, HtmlTable> be used together in C#?

Hi guys I am very new to C#, I am an intern currently doing a project for my company. I came across this which I don't really understand. Can Dictionary<string, HtmlTable> tableTracker = new Dictionary <string, HtmlTable>(); be used together? because I am trying to save my data into my database but when I run line by line it skips the line which leads to the definition above. Sorry if I did not provide enough information, I will try to provide it from your feedback. Thanks in advance.
