Question: indexer on foreach #36

Closed DominiqueFonteyn closed 5 years ago

DominiqueFonteyn commented 5 years ago

Hi,

I have question about the syntax you used in some of the Index pages. For instance, Course - Index

There is a foreachloop that creates a table row for each Course, but instead of using the itemvariable you use an indexer to access the properties of that Course.

@Html.Display(modelItem => modelItem.Courses[i].CourseID)

What is the reason for doing it like this?

Thanks for helping me out.

It’s part of a demo around putting unique IDs for table rows for view screens.
