问题 I'm very comfortable with .NET objects and its framework for reference vs value types. How do python objects compare to .NET objects? Specifically, I'm wondering about equality obj1 == obj2 , hash-ability (i.e. being able to put in a dict), and copying. For instance, by default in .NET, all objects are reference types and their equality and hash code is determined by their address in memory. Additionally, assigning a variable to an existing object just makes it point to that address in memory

问题 I have a C++ dll which is used to card printing( ID cards ). My implementation done using C#.Net. I used following code to call c++ dll. [DllImport(@"J230i.dll",CallingConvention = CallingConvention.Cdecl,SetLastError=true)] public static extern int N_PrintJobStatus(ref int[] nPrtintjobStatus); int[] pJob = {0,0,0,0,0,0,0,0} ; ret = N_PrintJobStatus( ref pJob); N_PrintJobStatus method signature given as bellow N_PrintJobStatus(int *pJobStatus ) After calling the method it gives following

问题 I'm programming with Tasks and await/async. I assumed that the multithreading works like it does in NodeJS or Python, that is, it doesn't, everything just runs on the same thread. But I've been trying to learn how Tasks actually get executed and my understanding is that they're executed by TaskScheduler.Default who's implementation is hidden but can be expected to use a ThreadPool. Should I be programming as if all my Tasks can run in any thread? The extent of my asynchronous programming is

问题 I have just included a DLL file into my project and am using a method which returns a List<Tuple> . I have only recently became aware of the ValueTuple datatype in C# 7 and want to use it instead of the normal Tuples which are returned. I am aware that I could loop through and do the conversion manually however I would like to avoid doing this if possible and was wondering if anyone was aware of a shorthand way to casting a Tuple to a ValueTuple? If I am being ignorant and this isn't possible

问题 var memStream = new MemoryStream(); using (var sw = new StreamWriter(memStream, Encoding.UTF8, 4194304 /* 4 MiB */, leaveOpen: true)) { var str = new string(Enumerable.Repeat(' ', 10240 /* 10 * KiB */).ToArray()); Console.WriteLine(str.Length); Console.WriteLine(Encoding.UTF8.GetBytes(str).Length); sw.Write(str); sw.Flush(); Console.WriteLine(memStream.Length); } // Output // --------- // 10240 // 10240 // 10243 // Output which I was expecting // --------- // 10240 // 10240 // 10240 I checked

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 3 years ago . Improve this question Processing the same .NET assembly (feeding the output of one into the other as input) with two different obfuscators increases the chance to make decompilation impossible? Thanks. 回答1: Decompilation is never impossible. It may though quite easily get to

问题 I have ListView which I am binding to a Dictionary collection, but new new items are added to the collection, the listview is not updating. How this can be achieved in WPF? 回答1: Both sides of WPF binding should support INotifyCollectionChanged interface in order to notify about collection changes. Dictionary does not support it. So you can either use ObservableCollection class (it does not provide functionality like search a value by associated key), or you can create you own

问题 I'm trying to asynchronously show a progress form that says the application is running while the actual application is running.
