问题 Let's say I have two class Foo and Bar as follows public class Foo { private Bar _bar; private string _whatever = "whatever"; public Foo() { _bar = new Bar(); } public Bar TheBar { get { return _bar; } } } public class Bar { public string Name { get; set; } } I have an application that attaches to a process that is using these classes. I would like to see all instances of Foo type in .NET heap and inspect the TheBar.Name property or _whatever field of all Foo instances present in .NET heap. I

问题 I am operating in the .NET Framework using ASP.NET MVC 5. I have an MVC Controller that is using Newtonsoft.Json (or json.net) to build a nice JSON object. The trouble I'm running into is that when I return my json using the JsonResult method Json(JSONdotnetObject) , I end up with a result that has the same structure as what I would expect but everything is empty JArrays like so: Expected: { "prop": { ... some stuff ... }, "another prop": { ... more stuff ... } } Actual: [ [ ... empty ... ],

问题 I need to control the GPIO pins of a CP210x device using CP210xManufacturing.dll and CP210xRuntime.dll provided by Silicon Labs. I manage to open and close the device and to get the part number. (In my case a CP2105). I think I successfully read the latch, but I'm not sure. I also call the write latch function, and no error is returned and neither do any pins toggle. According to the provided utility (CP21xxCustomizationUtility.exe) it shows that both ports are in GPIO mode. Here is my code:

问题 Disclaimer - I'm not familiar with Python. I'm a C# developer who has written an application to execute Python scripts (authored by others) using IronPython. These scripts have so far have only needed to use import math , but one of our users has asked for the application to support for Numpy. I have installed Numpy on my PC (using the 'numpy-1.9.2-win32-superpack-python2.7.exe' file), which has created a numpy folder under \Lib\site-packages. I've written a two-line Python script to test

问题 I need to play PowerPoint slides but first I want to check whether PowerPoint or viewer is installed on the machine or not. How can I do that using .NET? 回答1: It depends on whether you are trying to tell whether you can view a presentation (*.ppt, *.pptx, etc) or whether you can access the PowerPoint object model. To check whether there is an associated handler for ppt files, you can do the following: // using Microsoft.Win32; private bool CheckPowerPointAssociation() { var key = Registry

问题 I was trying to clone an List in my code, because I needed to output that List to some other code, but the original reference was going to be cleared later on. So I had the idea of using the Select extension method to create a new reference to an IEnumerable of the same elements, for example: List<int> ogList = new List<int> {1, 2, 3}; IEnumerable<int> enumerable = ogList.Select(s => s); Now after doing ogList.Clear() , I was surprised to see that my new enumerable was also empty. So I
