类型推断 [英] Type inference
问题描述
人们在这里怎么看待VB2008能够推断类型？
例如你现在可以说Dim i = 5
这会创建一个整数
就个人而言，我不喜欢它，因为它不一致，可能会混淆
其他devleopers阅读。
极端的例子 - 下面的x是什么类型的？
dim x = 4294967295
它也会导致不一致 - 有时你必须声明类型和
有时候你不用。
我将使用Option Infer Off

What do people here think about VB2008 having the ability to infer type?
e.g you can now say Dim i=5
which will create i as an integer
Personally I do not like it as it is not consistent and may be confusing for
other devleopers to read.
Extreme example - what is the type of x below?
dim x= 4294967295
It also leads to inconsistency - sometimes you have to declare the type and
sometimes you dont.
I will be using Option Infer Off

我完全同意。了解数据类型是非常基础和重要的
表面处理它们。 （我想知道是谁要求这样的功能）

I totally agree. Being aware of data types is much too basic and important
to deal with them superficially. (I wonder who asked for such a feature)

我不得不说我不介意。
I have to say I don''t mind it.

什么不一致？
What''s not consistent?
极端的例子 - 什么是类型下面的x是什么？
dim x = 4294967295
Extreme example - what is the type of x below?
dim x= 4294967295
无论什么数字类型都是nessecary存储4294967295.
我认为它（类型推断）可以降低页面上的噪音，而且我看不到
我们通过使用它会失去很多。

Whatever numeric type is nessecary to store 4294967295.
I think it (Type inference) reduces noise on the page and I don''t see that
we''re loosing much by using it.

我个人不喜欢它因为它不一致，可能是其他开发人员难以阅读的b $ b。

类型推断是支持LINQ所必需的。这是因为它将
添加到C＃中的原因相同。所以，虽然我看到了滥用的巨大潜力 - 我希望它会被明智地使用。

Type Inference is necessary to support LINQ. It''s the same reason it
is being added to C#. So, while I see a big potential for abuse - I
hope that it will be used judiciously.
