我需要在multiplyMatrixByConstant方法中使用矩阵数组，但我不确定如何使用

Question

我收到一个multiplyMatrixByConstant();的错误，它说"；没有给出与所需的形式参数"相对应的自变量；我不确定要包括什么来允许我在multiplyMatrixByConstant();方法中使用矩阵阵列

public class Program
{
public static void Main()
{
Console.WriteLine("              ----------Welcome to the Matrix Program----------");
Console.WriteLine("Please select one of the following options:");
Console.WriteLine("1: The Random Matrix");
Console.WriteLine("2: The Transpose Matrix");
Console.WriteLine("3: Multiplying a Matrix by a Constant");
Console.WriteLine("4: Multiplying Two Matrices");
Console.Write("Your choice is: ");
string choice = Console.ReadLine();
if (choice == "1")
{
generateMatrix();
}
else if (choice == "2")
{
generateTranspose();
}
else if (choice == "3")
{
multiplyMatrixByConstant();
}
}
static int[, ] generateMatrix()
{
Console.Write("Enter the number of columns: ");
int c = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter the number of rows: ");
int r = Convert.ToInt32(Console.ReadLine());
int[, ] matrix = new int[c, r];
Random rnd = new Random();
Console.WriteLine("The Matrix is: ");
for (int i = 0; i < c; i++)
{
for (int x = 0; x < r; x++)
{
matrix[i, x] = rnd.Next(0, 10);
}
}
for (int i = 0; i < c; i++)
{
for (int x = 0; x < r; x++)
{
Console.Write(matrix[i, x] + " ");

Console.WriteLine(" ");

return (matrix);

您需要收入参数(int[，]matrix，int c和int r(。
