VB和隐式转换 [英] VB and implicit conversions
问题描述
我有一个隐式转换设置在一个程序集中从Stream到
别的东西。在C＃中，它可以工作。在VB中它没有。
VB是否支持隐式转换？如果是这样，任何想法为什么它会在
a C＃程序中运行而不是VB？

I have an implicit conversion set up in an assembly from a Stream to
something else. In C#, it works. In VB it does not.
Does VB support implicit conversions? And if so any idea why it would work in
a C# program but not VB?

推荐答案
乍得，
不，VB在当前版本中不支持隐式转换。也就是说，它不支持非原始类型的隐式转换。只有Whidbey
才会支持（并且希望在使用隐式运算符时，它会产生与C＃生成的代码兼容的代码。）在
同时，你必须使用DirectCast关键字取消装箱物品。

Chad,
no, VB doesn''t support implicit castings in the current version. That is, it
doesn''t support implicit castings from non-primitive types. Only Whidbey
will support that (and hopefully it will be produce code that is compatible
with the code generated by C# when using the implicit operator); in the
meanwhile, you have to use the DirectCast keyword to unbox an object.

Ack。 :(
我明白VB和C＃之间存在差异。但MS怎么能把这样的东西留下来呢？Esp来自VB，国语反型
安全。你可以在哪里字符串=整数。:(
你能给我一个DirectCast的例子吗？

Ack. :(
I understand that there are differences between VB and C#. But how can MS
leave someting like this out? Esp from VB, the king language of anti type
safety. Where you could string = integer. :(
Can you give me an example of DirectCast?
