What are some examples of LINQ group operations?

Can you give me some examples of LINQ group operations?

Sure! LINQ group operations allow you to group data based on a key. For example, you can group a list of students by their grades.

How would that look in code?

Here's a simple example:

var groupedStudents = students.GroupBy(s => s.Grade);

This groups the students by their grade level.

What can I do with the grouped data?

You can iterate through each group and perform operations like counting, averaging, or displaying the grouped items.

Can you show me how to count the number of students in each group?

Absolutely! You can use:

foreach (var group in groupedStudents)
{
    Console.WriteLine($"Grade: {group.Key}, Count: {group.Count()}");
}
