dim k = new integer(9) {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

dim 和 as integer

for i = 0 to k.count - 1

和 += k(i)

next计算数组中各元素之和更简单的方法是

使用扩展方法sum或者lambda表达式，以下两种均可

dim 和1 = k.sum()

dim 和2 = k.aggregate(function(m, n) m + n)

在VB.net 中，如何用循环计算数组中各元素之和

'假设数组如下

dim d(10) as integer

dim i as integer

for i=lbound(d) to ubound(d)

d(i) = i

next i

'数组各元素之和

dim S as integer = 0

for i=lbound(d) to ubound(d)

s = s + d(i)

next i

msgbox(s)

VB.net中的求和问题

Private Sub Command1_Click()

MsgBox CalcResult(2)

End Sub

Public Function CalcResult(X As Long) As Double

Dim dblMinLevel As Double

Dim dblItem As Double

Dim dblN As Double

Dim dblMember As Double, dblBase As Double

Dim i As Double

Dim dblResult As Double

dblMinLevel = 10 ^ (-6)

dblN = 0

Do

dblMember = X ^ dblN

dblBase = 1

i = dblN

Do While i 1

dblBase = dblBase * i

i = i - 1

Loop

dblItem = dblMember / dblBase

dblResult = dblResult + dblItem

dblN = dblN + 1

Loop While dblItem = dblMinLevel

CalcResult = dblResult

End Function
