Remove the minimum inside a List in C# (Need Help)

Question

I am trying to remove the minimum value of a List, the main() function calls the removeSmallest() function and Writelines the return List, but all I get is:

"System.Collection.Generic.List`1[System.Int32]"

Varibles explanations: "n" --> counts how often the foreach-lopp ran in order to paste earlyer values in the List at the right time by saving them in, "posa" --> saves the spot for earlyer values to past them in the List at the right, "a" --> saves the previous number to compare it with the next one,

Lists: "numbers" --> is the input, "list" --> output,

You can find my Code here or [here][2]

THX for ur Help!!

Well, just Remove() a Min():

   List<int> numbers = new List<int>() {
     5, 3, 9, -2, 5, -2, 4 // please, notice that -2 appeared twice
   };

   // Just do this
   numbers.Remove(numbers.Min());

   // Let´s print out the test:
   // 5, 3, 9, 5, 4
   Console.Write(String.Join(", ", numbers));

LINQ can come in handy here, you can use this idea:

var numbers = new []{22,31,14,25,26,67,8,49,101};
var numbersNoLowest = numbers.OrderByDescending(x => x).Take(numbers.Count() - 1).ToList();
foreach(var number in numbersNoLowest)
{
    Console.WriteLine(number);    
}

I am not sure what your code is trying to do, but it doesn't remove the minimum value. If you want to remove all occurrences of the minimum value & leave the remaining values in the original order (which is what partially happens in your code) the following should work :

  int min = numbers.Min();
  List<int> list = numbers.Where(val => val != min).ToList();
