有关VB.NET输入数据的问题
我现在想求0到100内任何A到B之间所有整数的平方和(A <B,且都定义为整数)
现在怎么写输入语句了,就是随即输入两个数,因为不会,所以我只有把要输入的数据直接写在程序里了,如下:intnumber_1 = 3:intnumber_2 = 6!

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim intnumber_1, intnumber_2 As Integer
Dim total As Long
intnumber_1 = 3
intnumber_2 = 6
total = sum(intnumber_1, intnumber_2)
Label1.Text = total
End Sub
Function sum(ByVal a As Integer, ByVal b As Integer) As Long
Dim i, cubic As Integer
For i = a To b
cubic = i ^ 3 + cubic
Next
sum = cubic
End Function
End Class


[解决办法]
加两个textbox分别为txtInputDown和txtInputUp
intnumber_1=txtInputDown.text
intnumber_2=txtInputUp.text
