User input into a two dimensional array
提问by LostStudent
I'm completely new to C# and well I would like simple code to create a matrix from user input
我对 C# 完全陌生，我想要简单的代码来根据用户输入创建矩阵
E.G.
例如
int [,] matrix1 = new int [2,2]
// now using input i'd like to add integers into the array
matrix1[0,1] = Int32.Parse(Console.ReadLine()); // this is for user input
and so on.
等等。

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());

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]);
}
}

var numbers = new int[size, size];
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]);
}
