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
dimd(10)asinteger
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 = sd(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 i1
dblBase = dblBase * i
i = i - 1
Loop
dblItem = dblMember / dblBase
dblResult = dblResultdblItem
dblN = dblN1
Loop While dblItem = dblMinLevel
CalcResult = dblResult
End Function
