我对 C# 完全陌生，我想要简单的代码来从用户输入创建矩阵

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

等等。

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];

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]);     
    }
}

我试图在 C# 中找到该问题的一个很好的答案，我搜索了很多，直到一个朋友帮助我了解如何使用用户输入来完成它，所以我将把答案留在这里也许它可以帮助任何人

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] + " ");
    }
}

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());
