如何在 VB6 中检查对象是否为 Nothing? [英] How do I check for an object being Nothing in VB6?

问题描述

在我的 VB6 应用程序中，我有一个这样声明的对象数组...

In my VB6 application I have an array of objects declared thus...

Dim MyArray() as MyClass

这个数组随着处理的进行而被填充

This array is filled in as processing goes on

Set MyArray(element) = passed_object

由于不再需要元素，

Set MyArray(otherelement) = Nothing

使用数组时，我想使用像

When using the array, I want to use a loop like

For i = 1 To Ubound(MyArray)
    If MyArray(i) <> Nothing Then    ' Doesn't compile
        ...do something...
    End If
Next i

但我无法编译任何可能的东西.我也试过

But I can't get anything likely-looking to compile. I've also tried

If MyArray(i) Is Not Nothing Then

我是否应该这样做，如果是，我应该在这里进行什么测试?

Should I want to do this, and if so, what test should I put in here?

推荐答案

If Not MyArray(i) Is Nothing Then
