Dim f as Foo
set f = obj.FooArray(0)

这里有四个错误。 FooArray是一个属性，而不是一个函数。该属性不接受参数。 设置不正确，该属性返回一个数组，而不是对象。 f 的类型是错误的，该属性返回一个数组，而不是单个Foo。这应该更接近：

Four mistakes here. FooArray is a property, not a function. The property doesn't take an argument. Set is incorrect, the property returns an array, not an object. The type for f is wrong, the property returns an array, not a single Foo. This ought to be closer:

Dim f As Foo()
f = obj.FooArray
