呵呵 又开始啦 还是我来翻译吧~~
假设你向自己的一个Web应用中添加了一个新的Web页，而你所有的供应商都会用到这个Web应用。你需要在这个新页面中创建一个XmlDocument对象。请问下面的选项中哪个可以正确的在新页中把这个XmlDocument对象创建起来？
（每个选项都是一个完整的解决方案，选择所有你认为正确的选项）
A.这样创建对象：Dim xmlDoc As System.Xml.XmlDocument = CreateObject("XmlDocument").
B.这样创建对象：Dim xmlDoc As System.Xml.XmlDocument = CreateObject("System.Xml.XmlDocument").
C.在文件最上面增加一行 Imports Xml
然后这样创建： Dim xmlDoc as XmlDocument = New XmlDocument().
D.这样创建对象：Dim xmlDoc As System.Xml.XmlDocument = New System.Xml.XmlDocument().
E.这样创建对象：Dim xmlDoc as Object = New XmlDocument().
F.在文件最上面增加一行 Imports System.Xml
然后再这样创建： Dim xmlDoc as XmlDocument =New XmlDocument().

这次翻的比较烂，大家凑合看吧，应该没有强奸题意~~
我怎么觉得B D F都行啊

[VBDN]

参考答案：DF

[VBDN]

为什么B是错误的呢？请看下边原题注释：
You can create an XML document by creating an instance of the System.Xml.Xmldocument class.You can explicitly include the System.Xml namespace in the object creation code,or you can import the namespace by using the imports keyword at the top of the page.You must use the fully qualified namespace,System.Xml,with the imports statement.
The createObject function is used to create instances of COM objects.

[winstarr]

在这里 ，CreateObject 不能用？

[rib06]

哦，这样啊。把最关键的最后一句翻译一下吧：
createObject函数是用来创建COM对象实例的
