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
