无法传递多个参数

Question

我有一个看起来像这样的子程序。它有两个参数。

Sub Advance(ByRef listR() As String, rCount) 
    ...code 
End Sub 

当我尝试调用此：

Advance listR:=theList, theCount 

它给了我一个编译错误：

Expected: named parameter

这是为什么？它工作正常，就像...

Sub Advance(rCount) 
    ...code 
End Sub 

，并通过调用：

Advance theCount 

或者也可与正好阵列参数。

Answer 1

我相信你可以叫你的子以下任何方式，但你不能名字的第一个参数，而不是命名第二个：

Advance listR:=theList, rCount:=theCount 
Advance rCount:=theCount, listR:=theList 
Advance theList, rCount:=theCount 
Advance theList, theCount 

Call Advance(listR:=theList, rCount:=theCount) 
Call Advance(rCount:=theCount, listR:=theList) 
Call Advance(theList, rCount:=theCount) 
Call Advance(theList, theCount)

从MSDN：

When you supply arguments by a mixture of position and name, the positional arguments must all come first. Once you supply an argument by name, the remaining arguments must all be by name.
