I am writing a C# program that uses LINQ. This is what it is supposed to do: Take a sequence of integers Remove all odd integers, leaving only even ones Squares each integer Removes any resulting integer that is greater than 50 But I am getting a System.Linq.Enumerable+WhereEnumerableIterator`1[System.Int32] error. What is causing it and how can I fix it?

Question

I am writing a C# program that uses LINQ. This is what it is supposed to do:

Take a sequence of integers
Remove all odd integers, leaving only even ones
Squares each integer
Removes any resulting integer that is greater than 50

But I am getting a System.Linq.Enumerable+WhereEnumerableIterator`1[System.Int32] error. What is causing it and how can I fix it?

var numbers = Enumerable.Range(1, var evenNumbers = numbers.where(n Console.WriteLine(evenNumbers); 10); => n % 2 == 0); // combine projection and filtering var oddSquares = numbers.Select(x => x * x).where(y => y % 2 != 0); Console.WriteLine(oddSquares); // filter by type object[] values = { 1, 2.5, 3, 4.56 }; var wholeNumbers = values.OfType<int>(); // try float or double Console.WriteLine(wholeNumbers); var rand = new Random(); var randomValues = Enumerable.Range(1, 10).Select(_ => rand.Next(10) - 5); var csvString = new Func<IEnumerable<int>, string>(values => { return string.Join(",", values.Select(v => v.ToString()).ToArray());| }); // different set of values each time Console.WriteLine(csvString(randomValues)); Console.WriteLine(csvString(randomValues.OrderBy(x => x))); Console.WriteLine(csvString(randomValues.OrderByDescending(x => x)));
