Question

我正在尝试使用Visual Basic.NET实现一个简单的计算输出总价

我想阅读原价和运费重量，然后在计算中使用它。问题是，当我输入任何值时，两个变量都只返回第一个数字

例如，如果输入23，则返回2

    Dim originalPrice As Double
    Dim commissionPrice As Double
    Dim shippingWeight As Double
    Dim totalPrice As Double   

    Console.Write("Enter Original Price: ")
    originalPrice = Double.Parse(Console.ReadLine(originalPrice))

    Console.Write("Enter Shipping Weight: ")
    shippingWeight = Double.Parse(Console.ReadLine(shippingWeight))   
    shippingWeight = shippingWeight * 7

    If (originalPrice + shippingWeight >= 200) Then
        commissionPrice = (originalPrice + shippingWeight) * 0.03
    Else
        commissionPrice = 5
    End If

    totalPrice = commissionPrice + originalPrice + shippingWeight

    Console.WriteLine(originalPrice)
    Console.WriteLine(commissionPrice)
    Console.WriteLine(shippingWeight)       
    Console.WriteLine(totalPrice)

我认为您的问题是您将变量传递给Console.read（）

以这种方式应该工作。

    Dim originalPrice As Double
    Dim commissionPrice As Double
    Dim shippingWeight As Double
    Dim totalPrice As Double

    Console.Write("Enter Original Price: ")
    originalPrice = Double.Parse(Console.ReadLine())

    Console.Write("Enter Shipping Weight: ")
    shippingWeight = Double.Parse(Console.ReadLine())
    shippingWeight = shippingWeight * 7

    If (originalPrice + shippingWeight >= 200) Then
        commissionPrice = (originalPrice + shippingWeight) * 0.03
    Else
        commissionPrice = 5
    End If

    totalPrice = commissionPrice + originalPrice + shippingWeight

    Console.WriteLine(originalPrice)
    Console.WriteLine(commissionPrice)
    Console.WriteLine(shippingWeight)
    Console.WriteLine(totalPrice)

    Console.Read()

Visual Basic从键盘读取
