加上总费用

Question

我正在尝试让TotalCost为其添加150，然后如果该区域更大，那么750再次为TotalCost添加50。

int TotalCost = 0;
double Area = Convert.ToDouble(SurfAreaTxt.Text);

if (WoodTxt.Text.ToLower() == mahogany)
{
    TotalCost + 150;
    if (Area > 750)
    {
        TotalCost += 50;
    }
    Console.Write(TotalCost);
}

Answer 1

你几乎拥有它，只需将TotalCost + 150;更改为TotalCost += 150;。

你走了：

TotalCost = 0;
double Area = Convert.ToDouble(SurfAreaTxt.Text);

if (WoodTxt.Text.ToLower() == mahogany)
{
    TotalCost += 150;

    if (Area > 750)
        TotalCost += 50;

    Console.Write(TotalCost);
}
