C# bubble sort function returning data type not results?? code issue or file set up?

Very new to C# and completely new to C# in VS code. Im not sure if there is an issue with my code or the application file set up, in either case the return value I receive is System.Int32[], not the actual array contents.

I created a console project - dotnet new console -n "algos"

I added a solution file - dotnet new sln -n "algorythems_solution"

I added project to solution - dotnet sln algorythems_solution.sln add ./algos/algos.csproj

To run the program I have used f5 and - dotnet run

using System;

namespace algos
{
    class sortingAlgorythems
    {
        static void Main()
        {
            int[] test = {-4,5,10,8,-10,-6,-4,-2,-5,3,5,-4,-5,-1,1,6,-7,-6,-7,8};
            int[] sorted = bubbleSort(test);
            Console.WriteLine(sorted.ToString());
        }
        public static int[] bubbleSort(int[] array)
        {
            bool isSorted = false;
            int toValue = array.Length - 1;
            int fromValue = 0;
            while (isSorted == false) 
            {
                isSorted = true;
                int cnt = 0;
                for (int i = fromValue; i < toValue; i++) 
                {
                    if (array[i] > array[i+1])
                    {
                        cnt = i;
                        int temp1 = array[i];
                        int temp2 = array[i+1];
                        array[i] = temp2;
                        array[i+1] = temp1;
                        if (isSorted == true)
                        {
                            isSorted = false;
                            if (i > 0)
                            {
                                fromValue = i -1;
                            }
                        }
                    }
                }
                toValue = cnt;
            }
            return array;
        }
    }
}

Any insights into what my issue may be are greatly appreciated.

Here's an example generic extension method. Note it must be defined in a public static class.

public static void WriteToConsole<T>(this IList<T> list)
{
    for(int i = 0; i < list.Count; ++i)
    {
       Console.WriteLine(list[i]);
    }
}

Can be used like this:

int[] arr;
arr.WriteToConsole();

You have incorrectly assumed what ToString() does. The default behavior is to simply display the type of the object (though it is overridden for many types to display something more useful).

Here's a simple solution for you:

        int[] sorted = bubbleSort(test);
        for(int i = 0; i < sorted.Length; ++i)
        {
           Console.WriteLine($"{i}: {sorted[i]}");
        }
