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

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] + " ");
    }
}
