Writing out input numbers to console application,C#

I have a program that asks for a number (int x). then, the user should input x numbers to the console. And the console should add all the numbers together and write out the result of all the input numbers. So I've done this:

Console.WriteLine("Enter an number: ");
int x = int.Parse(Console.ReadLine());

for (int i = 0; i < x; i++ )
{
    Console.WriteLine("Ange tal {0}: ",i );
    double numbers= double.Parse(Console.ReadLine());
}

Console.WriteLine("Sum of the entered numbers are: {0} ",x);
Console.ReadLine();

But the the result only gives me the last entered number. What am I doing wrong?

    Console.Write("Enter N number: ");
    double numberN = double.Parse(Console.ReadLine());
    double sum = 0;

    for (double i = 0; i < numberN; i++)
    {

        Console.Write("Enter number: ");
        double number = double.Parse(Console.ReadLine());
        sum += number;

    }

    Console.WriteLine("The sum is: {0}", sum);

You need to make a variable where you will store the sum of the numbers (sum). Then after you read the next number, you should add it to your sum.

Console.WriteLine("Enter a number: ");
int x = int.Parse(Console.ReadLine());
double sum = 0;
for (int i = 0; i < x; i++ )
{
   Console.WriteLine("Ange tal {0}: ", i);
   double number = double.Parse(Console.ReadLine());
   sum += number;
}

Console.WriteLine("Sum of the entered numbers is: {0}", sum);
Console.ReadLine();

Here there is the code, with the Write and WriteLine correctly formatted.

Console.Write("Enter an number: ");
int x = int.Parse(Console.ReadLine());

double sum = 0;

for (int i = 0; i < x; i++)
{
    Console.Write("Ange tal {0}: ", i);
    double number = double.Parse(Console.ReadLine());
    sum = sum + number;
}

Console.WriteLine("Sum of the entered numbers are: {0:R} ", sum);
Console.Write("Press a key to exit");
Console.ReadKey();

But now we want to go a step forward: try inserting:

2
0.1
0.2

(or 0,1 and 0,2 if you use , as the decimal separator)

I always think that OMG Ponies!!! (Aka Humanity: Epic Fail) is the best reading possible...

You can do it like this

Console.WriteLine("Enter an number: ");
int x = int.Parse(Console.ReadLine());
List<double> allNumbers = new List<double>();
for (int i = 0; i < x; i++ )
{
      Console.WriteLine("Ange tal {0}: ",i );
      double temp;
      if(double.TryParse(Console.ReadLine(), out temp))
         allNumbers.Add(temp);
      else
          Console.WriteLine("Enter a valid number");  
}

Console.WriteLine("Sum of the entered numbers are: {0} ",allNumbers.Sum());
Console.ReadLine();

You never actually do any summation in your code. 

double sum = 0;
for (int i = 0; i < x; i++ )
{
    Console.WriteLine("Ange tal {0}: ",i );
    double numbers= double.Parse(Console.ReadLine());
    sum += numbers;
}

    Console.WriteLine("Sum of the entered numbers are: {0} ",sum);

This way the sum of the inputed number will be shown 

Console.WriteLine("Enter an number: ");
        int x = int.Parse(Console.ReadLine());
        double sum = 0
        for (int i = 0; i < x; i++ )
        {
            Console.WriteLine("Ange tal {0}: ",i );
            sum = sum + double.Parse(Console.ReadLine());

        }

        Console.WriteLine("Sum of the entered numbers are: {0} ",sum);
        Console.ReadLine();
