[问题]关于编译器的几个问题 [英] [QUESTION] Few questions about a compiler

问题描述

首先：这不是代码问题，所以请忽略，如果您这么认为，这只是提供信息。



我是3年的程序员，其中2年c＃也许在3年后询问关于编译器的问题可能是一种耻辱，但我仍然必须知道这个：



1：我使用Visual Studio 2015，我在哪里可以看到我的当前的编译器？

2：我可以在visual studio中下载并设置一些新的编译器吗？

3：编译器有什么不同吗？

- 我听说，编译器有所不同，但究竟有多大？因为无论采用何种方法翻译代码，最后都必须是二进制数据...

4：为什么我应该选择不同的编译器（如果可能的话），如果可以，给出一些例子。

first: this is not problem with code, so ignore if you think so, this is just informative.

Im 3 years programmer, in which 2 years c#, maybe its a shame to ask question about compiler after 3 years but still i just must know this:

1: Im using Visual studio 2015, where can i see my the current compiler?
2: Can i download and set some new compiler in visual studio?
3: Are there much difference in the compilers?
- i heard that, compilers make difference, but how big exactly? since on whatever method its translating the code, at the end, it must be binary data...
4: Why should i choose different compilers (if possible), give some example if you can.

推荐答案

1）嗯......技术上你不能看到它 - 它只是磁盘上的字节集合。

但是......它被称为CSC.EXE，您可以在 C：\ WINDOWS \ MicroStoswork \ Framework 目录下的各种文件夹中找到它 - 每个版本都在一个单独的文件夹中。

2,3,4）为什么？没有很多其他C＃编译器--MONO有一个，XAMARIN也是如此，但说实话，就IL输出而言，它们非常多。当我们谈论C和C ++的时候，有很多不同的编译器，每个都比其他编译器更好吃了一件事 - 但现在它几乎都是Windows下的MS，除非你在谈论编译不同的目标处理器。由于C＃编译为IL，因此不会发生这种情况。

1) Well...technically you can't "see" it - it's just a collections of bytes on the disk.
But...it's called "CSC.EXE" and you'll find it in various folders under the C:\WINDOWS\Microsoft.NET\Framework directory - each version in a separate folder.
2, 3, 4) Why? There aren't many other C# compilers - MONO has one and so does XAMARIN, but to be honest they are much of a muchness as far as IL output goes. When we were talking about C and C++ there were a large number of different compilers, and each was "better" ate one thing than the others - but now it's pretty much all MS under windows unless you are talking about compiling for a different target processor. Since C# compiles to IL, that situation doesn't really occur.
