如何在C＃中填充2D数组？ [英] how to populate a 2D array in C#?

问题描述

我正在尝试使用随机值填充c＃中的二维数组..我已经坚持了......这是我的代码

i'm trying to populate a 2d array in c# using random values .. i've stucked...here is my code

Random random = new Random();
int[ , ] numbers = new int[ no_of_rows , no_of_columns ];

 int row_value = 0;
 int column_value = 0;

// populating 2D Array

for (int m = 0; m < 5 ; m++)
{
    for (int n = 0; n < 5 ; n++)
    {
        row_value = random.Next(0,25);
        column_value = random.Next(0, 25);
        numbers[m,n] = [row_value,column_value];
    }
}

推荐答案

// random integer returned can include this value
private const int randMinimum = 0;

// note that random integer returned maximum value will be 
// one less than the value specified: i.e., in this case, #25
private const int randMaximum = 26;

private const int no_of_rows = 5;
private const int no_of_columns = 5;

// fancy way of getting more randomness than you will probably ever need
private Random random = new Random(Guid.NewGuid().GetHashCode());

private int[ , ] numbers = new int[ no_of_rows , no_of_columns ];

// populating 2D Array        
for (int row = 0; row < no_of_rows; row++)
{
    for (int column = 0; column < no_of_columns; column++)
    {
        numbers[row, column] = random.Next(randMinimum, randMaximum);
    }
}

试试以下代码

Try the below code

Random random = new Random();
int[ , ] numbers = new int[5,5];
//populating 2D Array
for (int m = 0; m < 5 ; m++)
{
    for (int n = 0; n < 5 ; n++)
    {
        numbers[m,n] = random.Next(0, 25);
    }
}
