Question

我将值分配给变量，如下所示：

private string[] numbers = new string[] {"1" , "2" , "3" , "4" , "5"};

然后我拿出我的数字变量，我按照以下过滤每个

 protected void display()
    {

        bonusdiv.Visible = true; 
        panelbonus.InnerHtml = "";

        foreach (string option in numbers)
        {
            string optiontext = option;
            if (option.Length == 1)
            {
                optiontext = "" + optiontext;
            }

            if (panelBonusselections.Contains(option))
            {
                panelbonus.InnerHtml += "<input name=\"_bonus1_" + option + "\" id=\"/_bonus1_" + option + "\" type=\"submit\" value=\"" + optiontext + "\" class=\"optionselected\"/>";
            }
            else
            {
                panelbonus.InnerHtml += "<input name=\"_bonus1_" + option + "\" id=\"/_bonus1_" + option + "\" type=\"submit\" value=\"" + optiontext + "\" class=\"option\"/>";
            }

        }
    }

现在我提出的问题是，我想将上面提到的值分配到单个实例中，例如

numbers=[5]; //but this must still use the same logic as above to store the values from 1 up to 5.Then how do i cater for this change in my foreach loop?

它会像波纹管一样吗？

int numbers = [5]

for (i=1,i>5, i++) {
  foreach (string option in numbers)
        {
            string optiontext = option;
            if (option.Length == 1)
            {
                optiontext = "" + optiontext;
            }

            if (panelBonusselections.Contains(option))
            {
                panelbonus.InnerHtml += "<input name=\"_bonus1_" + option + "\" id=\"/_bonus1_" + option + "\" type=\"submit\" value=\"" + optiontext + "\" class=\"optionselected\"/>";
            }
            else
            {
                panelbonus.InnerHtml += "<input name=\"_bonus1_" + option + "\" id=\"/_bonus1_" + option + "\" type=\"submit\" value=\"" + optiontext + "\" class=\"option\"/>";
            }

您可以使用LINQ＆＃39; Enumerable.Range()来创建序列，并使用Select()将其投影到字符串：

string[] numbers = Enumerable.Range(1, 5).Select(i => i.ToString()).ToArray();

或作为一种方法：

string[] GetNumbersStringArray(int length)
{
    return Enumerable.Range(1, length).Select(i => i.ToString()).ToArray();
}

如何在for循环或linq中加载变量
