主题：自定义函数为何不执行 Do...Loop语句

Dim d As String = "1250/300"  '公约数
Dim x As Integer = math.min(val(d.SubString(0,d.Indexof("/"))),val(d.SubString(d.Indexof("/")+1)))
Dim y As Integer = math.mAx(val(d.SubString(0,d.Indexof("/"))),val(d.SubString(d.Indexof("/")+1)))
If val(d.SubString(0,d.Indexof("/"))) = 0 Then
    y = 0
    Return y
Else
    Dim temp As Integer
    Do While x <> 0                  
        temp = y Mod x   
        y = x    
        x = temp
    Loop
End If
y = math.abs(y)
Return(y)

上面代码在命令窗口执行时正确，在自定义函数中运行时出错，用帮助实例运行也出错。如自定义函数名称：“函数1”

Dim i As Integer = args(0)
Dim Sum As Integer
Do While i < 100
    Sum = Sum + i
    i= i + 2
Loop
Return Sum

命令窗口执行：output.show(Functions.Execute("函数1"),1)

错误提示：

编译错误:“Public Shared Sub Show(O10llO0 As String)”的参数太多。

错误代码：output.show(Functions.Execute("函数1"),1)

已解决，“）”位置错误
