为在python中使用dotnet程序安装clr

直接在命令行中录入

pip install pythonnet

会有一个ssl错误提示

...Could not fetch URL https://pypi.python.org/simple/pythonnet/: There was a problem confirming the ssl...

只好下载后再安装，下载地址

https://pypi.org/simple/pythonnet/

我的python是2.7的32位，于是下载了

pythonnet-2.3.0-cp27-cp27m-win32.whl

直接放在D盘，在命令行转到D盘，执行以下命令

pip install pythonnet-2.3.-cp27-cp27m-win32.whl

安装成功，可以import clr啦：）

vs.net2017也可以新建python项目，我在其上安装的是python3.6，且是64位的，这很有意思，命令行默认是2.7的，vs.net里跑的是3.6的，太方便了。vs.net2017的3.6安装clr就太方便了。

录入组件名称，点击运行pip...

好了，帖一段python里打开wpf的程序的代码，代码来自这个地址
