User input into a two dimensional array

Question

I\'m completely new to C# and well I would like simple code to create a matrix from user input

E.G.

int [,] matrix1 = new int [2,2]
// now using inpu         


        

Answer 1

int[,] A = new int[5, 4];

//read
for (int i = 0; i < 5; i++)
{
    for (int j = 0; j < 4; j++)
    {
        A[i, j] = int.Parse(Console.ReadLine());  
    }
}

//Write
for (int i = 0; i < 5; i++)
{
    Console.WriteLine();

    for (int j = 0; j < 4; j++)
    {
        Console.Write(A[i, j]);
    }
}

Answer 2

var numbers = new int[size, size];

            for (var i = 0; i < size; i++)
            {
                var numList = new string[size];
                numList = readLine.Split();
                for (var j = 0; j < size; j++)
                {
                    numbers[i, j] =convert.ToInt32(numList[j]);                        
                }

}

Answer 3

static void Main(string[] args)
{
   int[,] matrix1 = new int[2, 2];

   for (int i = 0; i < 2; i++)
   {
         for (int j = 0; j < 2; j++)
         {
            matrix1[i, j] = Int32.Parse(Console.ReadLine());  
         }
   }

   for (int i = 0; i < 2; i++)
   {
          for (int j = 0; j < 2; j++)
          {
             Console.WriteLine("Element({0},{1})={2}", i, j, matrix1[i, j]);
          }
   }
}

Answer 4

I was trying to find a good answer to that question in C#, I searched a lot until a friend helped me to understand how to do it with user input, SO I will leave the answer here maybe it could help anyone

int n = int.Parse(Console.ReadLine()); //the size of the array
int m = n;
int[,] arr = new int[n, m];
string[]lines = new string[n]; // so we could read the input from the user
for (int i = 0; i < n; i++) // here we need to read more than one line
{
    lines[i] = Console.ReadLine();
}


for (int i = 0; i < n; i++)
{
    string[]num = lines[i].Split(' ');
    for (int j = 0; j < m; j++)
    {
        int z = Convert.ToInt32(num[j]);
        arr[i, j] = z;
    }
}

for (int i = 0; i < n; i++)
{
    Console.WriteLine();
    for (int j = 0; j < m; j++)
    {
        Console.Write(arr[i, j] + " ");
    }
}

Answer 5

Console.WriteLine("Enter the height: ");
int h = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter the width: ");
string w = Convert.ToInt32(Console.ReadLine());

int[,] arr = new int[w, h];

for (int i = 0; i < w; ++i)
  for (int j = 0; j <h; ++j)
    arr[i, j] = Convert.ToInt32(Console.ReadLine());

Answer 6

var numbers = new int[size, size];

for (var i = 0; i < size; i++)
{
    var numList = new string[size];
    numList = readLine.Split();
    for (var j = 0; j < size; j++)
    {
        numbers[i, j] = Convert.ToInt32(numList[j]);     
    }
}
