对象实例化快捷方式 [英] Object instantiation shortcuts
问题描述
是否可以允许对象实例化的扩展语法，所以
代替
Hashtable< string，int> table = new Hashtable< string，int>（10,10f）;
我可以写：
Hashtable< string，int> table（10,10f）;
这是可能的还是编译器不明确？
在某些情况下它会非常特别是在使用仿制药时很有用。

would it be possible to allow an extended syntax for Object instantiation so
that instead of
Hashtable<string,int> table = new Hashtable<string,int>(10, 10f);
I can write:
Hashtable<string,int> table(10, 10f);
Would this be possible or is this ambiguous to the compiler?
In some situations it would be very useful especially when using generics.

我真的希望这*不会发生 - 只是因为此刻，
当你''时，它非常清楚重新明确地创建一个新对象。打字数量的
差异真的那么重要吗？

I really hope this *doesn''t* happen - simply because at the moment,
it''s very clear when you''re explicitly creating a new object. Is the
difference in the amount of typing really that important?

它可能但可能是不可取的。正如乔恩所说，它并没有使得新实例的创建成为可能，我认为它在C ++中有不同的含义
（本地或显式的堆栈构造）转换或其他东西，
它是C ++的一小部分内容之一我从来没有想过要帮助使语言变得非常复杂的
。
无论如何，一个不错的IDE修复了这个问题，vs2005已经自动插入
所有内容直到第一个（当你点击右键时（没有它）
infront of e e，不确定密钥）。这可能是一个工具问题更多
而不是语言一。我会告诉你，你不能总是使用IDE'，但我
会怀疑你可以而且应该花费大部分时间。
Its possible but probably undesireable. As Jon said, it doesn''t make
creation of a new instance possible and I think it has a different meaning
in C++(stack construction of a local or explict conversions or something,
its one of those little tidbits of C++ I never got around to figuring out
that helps makes the language insanely complex).
Anyway, a decent IDE fixes this, vs2005 already automatically inserts
everything up to the first ( when you hit the right key(don''t have it
infront ofm e, not sure of the key). This is probably a "tools" problem more
so than a language one. I''ll give you that you can''t always use IDE''s, but I
would suspect most of hte time you can and should.

贡献愚蠢的建议是我的专业:)

Contribute stupid proposals are my specialitiy :)
正如乔恩所说，它没有'可以创建一个新的实例，我认为它在C ++中具有不同的含义（本地或显式转换的堆栈构造或其他东西，它是C ++的一小部分内容之一）我从来没有搞清楚
这有助于使语言变得非常复杂。）

我不确定你对显式转换的意思，但在C ++中语法
只调用给定变量的ctor。

Iam not sure what you mean with explicit conversion, but in C++ this syntax
only calls the ctor for the given variable.
