Reading array elements from the same line (C#)

Is it possible to read the elements of an array from the same line (from Console) in C#? I know it's possible to read multiple inputs from the console and storing the individual parts in different variables using Split(). But I can't understand how to do it in arrays.

Code

for (int i = 0; i < arrival.Length; i++)
{
     arrival[i] = int.Parse(Console.ReadLine());

}

For example, I have to enter the elements 34 35 36 37 in the array. If I use the above mentioned code, I have to enter each element in a separate line. But what I need is, if I enter 34 35 36 37 in the Console, it must store each number as an element in the array. How to do this?

you can do it in following manner for array of type integer

string readLine=Console.ReadLine());
string[] stringArray=readLine.split(' ');
int[] intArray = new int[stringArray.Length];
for(int i = 0;i < stringArray.Length;i++)
{
// Note that this is assuming valid input
// If you want to check then add a try/catch 
// and another index for the numbers if to continue adding the others
    intArray[i] = int.parse(stringArray[i]);
}

you need to read from console, split the input string, convert the splitted strings to your type (here to double), then add them to your own array:

here is the code doing what you want:

using System;
using System.Collections.Generic;
using System.Linq;

namespace test4
{
class Program
{
    static void Main(string[] args)
    {
        List<double> arrayOfDouble = new List<double>(); // the array to insert into from console

        string strData = Console.ReadLine(); // the data, exmple: 123.32, 125, 78, 10
        string[] splittedStrData = strData.Split(new[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
        // trim then parse to souble, then convert to double list
        List<double> dataArrayAsDouble = splittedStrData.Select((s) => { return double.Parse(s.Trim()); }).ToList();

        // add the read array to your array
        arrayOfDouble.AddRange(dataArrayAsDouble);
    }
}
}

I am not clear with question, may be you are looking for this using System;

class Program
{
    static void Main()
    {
    string s = "there is a cat";
    // Split string on spaces.
    // ... This will separate all the words.
    string[] words = s.Split(' ');
    foreach (string word in words)
    {
        Console.WriteLine(word);
    }
    }
}

Output will be 

there
is
a
cat
