.NET Framework等同于ASCW& CHRW [英] .NET Framework Equivalent to ASCW & ChrW
问题描述
我真的宁愿使用dot-nettified语法而不是挖掘来自Microsoft.VisualBasic的
全局函数。
任何人都知道获得相同结果的新方法吗？

I would really rather use the "dot-nettified" syntax rather than digging
global functions out of Microsoft.VisualBasic.
Anyone know the newfangled way to achieve the same results?

如果你真的想要，你可以使用System.Convert类。
但是在使用ChrW / AscW之前我会三思而后行。它们是
编译时计算的表达式，导致代码比任何函数调用都更高效。

Well if you really want to you can use the System.Convert class.
But I would think twice before using that over ChrW/AscW. They are
compile-time evaluated expressions that result in code that''s more
efficient than any function call ever can be.

我同意。 AscW和ChrW是可靠的功能，这是最优雅的方式
来做到这一点。例如，Convert.ToInt32将执行AscW的操作，但是你需要确保你只传递一个字符 - AscW将为你提供
通过只查看第一个字符，如果你传递一个字符串。
您可以使用''纯''.NET代码编写自己的AscW和ChrW函数，但是
有什么意义？ （经过严格测试的版本已经存在）

I agree. AscW and ChrW are reliable functions that are the most elegant way
to do this. For instance, Convert.ToInt32 will do what AscW does, but you
will have to ensure you''re passing exactly one character - AscW takes care of
that for you by only looking at the first character if you pass a string.
You could write your own AscW and ChrW functions using ''pure'' .NET code, but
what''s the point? (very well tested versions already exist)

好吧，如果你真的很想你可以使用System.Convert类。
但是在使用ChrW / AscW之前我会三思而后行。它们是编译时评估的表达式，导致代码比任何函数调用都更有效。

这不是马蒂亚斯所指出的。虽然在Strings命名空间中有名为AscW和ChrW的函数，但函数调用
不一定是你输入AscW（C）时得到的函数代码。
相反，它们是编译时表达式，导致不同的
编译代码，具体取决于您发送给它们的参数类型。 （我
我真的不知道该怎么称呼它们，它们的功能就像关键词，但是
它们不是关键词）。
相当于ChrW函数调用的是System.Convert.ToChar（）。
AscW更有趣。真的有.Net等价，因为
最多.Net语言不需要函数调用，但是当你指向
out时，Convert.ToInt32将使用单个
字符或多或少地做同样的事情。
That''s not exactly what Mattias was pointing out. While there are
functions named AscW and ChrW in the Strings namespace, that function call
is not necessarily what you get when you type AscW("C") into your code.
Rather, they are compile time expressions that result in different
compiled code depending on what parameter types you send to them. (I
don''t really know what to call them, they function like keywords, but
they aren''t keywords).
The equivalent to the ChrW function call is System.Convert.ToChar().
AscW is more interesting. There really isn''t a .Net equivalent since
most .Net languages don''t need a function call here, but as you point
out, Convert.ToInt32 will do more or less the same thing with single
characters.
您可以使用'编写自己的AscW和ChrW函数' '纯''.NET代码，但

好吧，如果你多次切换.Net语言或在多语言商店工作，
远离VisualBasic命名空间和
VB转换关键字是有利的。它是一个巨大的命名空间，有许多有用的
函数，它们与.Net的main
命名空间相似但不完全相同。如果你在语言中使用相同的功能，那么你不必担心细微的差别。
Well, if you switch .Net languages a lot or work in a multi-language shop,
there''s an advantage to staying away from the VisualBasic namespace and
the VB conversion keywords. It''s a huge namespace with many useful
functions that are similar but not quite identical to the "main"
namespaces of .Net. If you use the same functions across languages,
then you don''t have to worry about the subtle differences.
