问题 Given a list of FileInfo objects, how do I sort them by date? Specifically I want to sort them by CreationTime in descending order. 回答1: The Pythonic way of doing this would be: fileInfos = list(DirectoryInfo(path).GetFiles()) fileInfos.sort(key=lambda f: f.CreationTime, reverse=True) The list sort method takes a key function that is used to get the sort key for each item. 回答2: DirectoryInfo.GetFiles() returns an array of FileInfo objects. I created a generic list to hold the FileInfo objs,

问题 I'm building an IronPython module that initializes an instance of AutoCAD and I need to return 1 to the module calling it after AutoCAD has finished initializing, entered its message loop and is in a stable (not loading dependencies/anything) state. I've tried using System.Diagnostics.Process.WaitForInputIdle() with no luck. Here's what I have so far: import System.Diagnostics as sysdiag def start_autocad(self): print("\"C:\\Program Files\\Autodesk\\Autodesk AutoCAD Civil 3D 2014\\acad.exe\"

问题 I've noticed this behavior in sqlite. When I re-use the cursor object, the working set memory in the task manager keeps increasing until my program throws a out of memory exception. I refactored the code such that each time I query I open a connection to the sqlite file query what I want and then close the connection. The latter somehow seems to be not so memory-hungry. It doesn't increase beyond a certain point. All I do with my sqlite db is simple select (which contains two aggregations)

问题 In IronPython I can do: Console.WriteLine(int.MaxValue) where int is not a variable but rather System.Int32. I get back: Max of int: 2137483647 Yet if I try something similar for double (System.Double), I get: NameError: name 'double' is not defined. Similary for char (System.Char). How come? 回答1: See Mapping between Python builtin types and .NET types int is not a keyword, it is a builtin type in Python, and IronPython implements it using System.Int32 . Similarly float is implemented using

问题 I'm new at Python, and I'm trying to write my first Python application on Visual Studio CE 2015 using IronPython. I finally managed to execute the most basic .NET-compatible code importing the clr module (which comes with the whole IronPython package) but, since my goal is writing an application that reads from a USB scale following this blog post, I'm stuck at trying to import the usb module. I downloaded and installed both pyUSB and libusb, so I thought I had to simply add the reference in

问题 I am trying to write some code with IronPython and numpy that calls a .NET assembly. Version info: numpy-2.0.0-1 scipy-1.0.0-2 IronPython 2.7.1 I installed scipy and numpy according to the instructions given here: http://www.enthought.com/repo/.iron/ When I try to run with ipy64.exe I get the following: Failed while initializing NpyCoreApi: BadImageFormatException:An attempt was made to load a program with an incorrect format.

问题 This should (I think) have a simple answer, assuming that an answer exists. Is it possible to use IronPython to return the path of the current *.dxp project as a string? I use something similar in VBA frequently, and it's become pretty useful. I've tried looking, but I have a hard time working through TIBCO's Python material. :\ 回答1: The script below should help you with this. There are 2 ways to get the path of the analysis depending on if you are using a library file or a .dxp. Your
