如何以 C# 窗口形式顯示二維數組?

[英]how to display 2D array in C# windows form?

當我嘗試放置代碼以顯示它時,我不知道如何在 listboxt 上顯示它錯誤總是發生

int arrayRows = 5;
int arrayCols = 3;

int[,] arrayTimes;
arrayTimes = new int[arrayRows , arrayCols];
int mult = 0;

for (int i = 0; i != arrayRows; i++)
{
    mult = mult + 10;
    for (int j = 0; j != arrayCols; j++)
    {
        arrayTimes[i, j] = mult;
        mult = mult * 10;
    }

    mult = mult / 1000;
    listBox1.Items.Add("arrayPos= " + i + "values =" + arrayTimes[i,j]);            
}

嘗試這樣做:

int arrayRows = 5;
int arrayCols = 3;

int[,] arrayTimes;
arrayTimes = new int[arrayRows , arrayCols];
int mult = 0;

for (int i = 0; i != arrayRows; i++)
{
    mult = mult + 10;
    for (int j = 0; j != arrayCols; j++)
    {
        arrayTimes[i, j] = mult;

        listBox1.Items.Add("arrayPos= " + i + "values =" + arrayTimes [i,j]);

        mult = mult * 10;
    }
    mult = mult / 1000;
}

在退出for (int j = 0; j != arrayCols; j++){ ... }結構后,您正在使用j
