用循环或其他方式简化C＃行

Question

抱歉愚蠢的问题，无论如何要用循环来简化这一行，所以我可以执行N次，同时每次增加credit1和grade1？

    totalpoints = totalpointcalc(totalpoints, credit1.Text, grade1.Text);
            totalpoints = totalpointcalc(totalpoints, credit2.Text, grade2.Text);
            totalpoints = totalpointcalc(totalpoints, credit3.Text, grade3.Text);

如果你能提供一些见解，谢谢你们。）

Answer 1

一般来说，只要您拥有名为var1，var2，... varN的变量，就应该使用数组（或列表）。

创建一个数组来存储credit和grade控件，然后遍历这些数组：

var credit = new[] { credit1, credit2, credit3 };
var grade = new[] { grade1, grade2, grade3 };

...

for(var i = 0; i < credit.Length; i++)
{
    totalpoints = totalpointcalc(totalpoints, credit[i].Text, grade[i].Text);
}

Answer 2

您可以使用Enumerable.Aggregate方法使用匿名类型：

var creditGrades = new[]
{
    new { credit = credit1.Text, grade = grade1.Text },
    new { credit = credit2.Text, grade = grade2.Text },
    new { credit = credit3.Text, grade = grade3.Text }
};
var total = creditGrades.Aggregate(0, (i, x) =>
                totalpointcalc(i, x.credit, x.grade));
