C＃编译版C＃命令行编译 [英] C# compile version C# command line compilation

问题描述

我使用命令行编译

csc似乎停留在使用C＃编译器版本5.我希望它使用版本7

<我检查了csc的配置源文件，即csc.exe，这是我在那里看到的代码

<？ xml 版本 = " 1.0" ？>

解决方案

< 中的版本supportedRuntime
version = " v4.0.30319" />  与CLR有关，这是最新的;但
csc.exe的当前配置与此大不相同。

您可以使用此cmd行知道csc.exe支持哪种C＃语言版本：

csc.exe -langversion：？

如果您拥有的csc.exe不支持此类参数，那么它与VS2017无关。

I use command line compilation

csc seems to be stuck on using C# compiler version 5. I want it to use version 7

I checked the configuration source file for csc, that is csc.exe, and this is the code I see there

<?xml version ="1.0"?>

解决方案

The version in <supportedRuntime version="v4.0.30319"/> is related to the CLR, which is up to date; but the current config for csc.exe is much different than that.

You can know which C# language version csc.exe supports, using this cmd line:

csc.exe -langversion:?

If csc.exe you have doesn't support such parameter, then, it is not related to VS2017.
