Calling a Sub and returning a value
提问by Nefariis
This might seem like an insanely easy question, but I can't seem to find an answer anywhere to it. I'd like to think that I am decent at VB but while I was learning javascript the other day I found something that seemed awesome and now I can't figure out how to do it in VB.
这似乎是一个非常简单的问题，但我似乎无法在任何地方找到答案。我想认为我在 VB 方面很不错，但是前几天我在学习 javascript 时发现了一些看起来很棒的东西，现在我无法弄清楚如何在 VB 中做到这一点。
In javascript it looks like this:
在javascript中它看起来像这样：
var someValue = getThatValue()
var someValue = getThatValue()
It's both calling and setting the value from the getThatValue() sub. what is the VB equivalent?
它从 getThatValue() 子调用和设置值。什么是 VB 等价物？

I've tried doing this:
我试过这样做：
private sub main()
dim value = getValue()
'do something with value
end sub
private sub getValue()
return 3
end sub
That doesn't seem to work, how can I get that to work?
这似乎不起作用，我怎样才能让它起作用？

You should be using a Property:
你应该使用一个属性：
Private _myValue As String
Public Property MyValue As String
Get
Return _myValue
End Get
Set(value As String)
_myValue = value
End Set
End Property
Then use it like so:
然后像这样使用它：
MyValue = "Hello"
Console.write(MyValue)
