Can you provide an example of the result of a method that returns an object of type IQueryable?

A method that returns an object of type IQueryable typically represents a query to a database that has not yet been executed (lazy evaluation). For example, if we have a collection of users, the method might look like this:

public IQueryable<User> GetActiveUsers()
{
    return dbContext.Users.Where(u => u.IsActive);
}

The result of this method is an IQueryable<User> object, which can be further filtered, sorted, or have other operations performed on it. The database query will only be executed when enumerating over the results (for example, calling ToList(), FirstOrDefault(), etc.).

Example usage:

var activeUsersQuery = GetActiveUsers();
var activeUsersList = activeUsersQuery.ToList(); // The database query is executed here
