问题 I have a console app that queries a database and then posts some records to a REST API in a loop (the api does not support batch posting, so I have to loop through each record and post individually, if its relevant). The database access is fast and no issue and so is the api post loop according to the timer I've put in place, however the app itself takes a long time to exit after the work is done. This started happening after I introduced Parallel.Foreach to speed up the posting. Before using

问题 I have a project that targets .NET Standard 1.5 that is deployed as several DLLs on NuGet. The project was ported from Java. Inside some of the classes of the project are static Main() methods that are meant to be run from the command line. In .NET Core it seems there are 2 ways to compile a DLL: <OutputType>Exe</OutputType> - compiles into an executable console app (DLL) <OutputType>Library</OutputType> (default) - compiles into a class library (DLL) What I am wondering is there a way to

问题 I am currently creating a file copying facility that works on console. There are 3 basic classes that exist within this, the first one is the program itself which takes a source and destination and is as follows: class Program { static void Main(string[] args) { Console.WriteLine("Source:"); string path = Console.ReadLine(); Console.WriteLine("target:"); string target = Console.ReadLine(); Copy newCopy = new Copy(); newCopy.CopyFunction(path, target); Console.ReadLine(); } } The second class

问题 I've got a wpf "console" application with the following application class: public partial class App : Application { [DllImport("kernel32.dll", SetLastError = true)] static extern bool AttachConsole(uint dwProcessId); [DllImport("kernel32.dll", SetLastError = true)] static extern bool FreeConsole(); const uint ATTACH_PARENT_PROCESS = 0x0ffffffff; protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); AttachConsole(ATTACH_PARENT_PROCESS); Console.WriteLine("test1");

问题 I incorporated C++ shared library generated from MATLAB in a Win32 console application. The MATLAB program takes 2-3 sec to execute in MATLAB but the console application takes 11-12 seconds to execute. I read this is because of the start up time of MCR and I believe after the MCR is initialized it must take same time as it takes in matlab. So how can I load or initialize the MCR so that it is always in the RAM or cache so that it will take 2-3 sec for the console application to run? Should I

问题 I'm writting a program in C and I want to have Greek characters in the menu when I run it in cmd.exe . Someone said that in order to include Greek characters you have to use a printf that goes something like this: printf(charset:IS0-1089:uffe); but they weren't sure. Does anyone know how to do that? 回答1: Assuming Windows, you can: set your console font to a Unicode TrueType font: emit the data using an "ANSI" mechanism This code prints γειά σου : #include "windows.h" int main() {

问题 I'm trying to call a method from another class with a console application. The class I try to call isn't static. class Program { static void Main(string[] args) { Program p = new Program(); var myString = p.NonStaticMethod(); } public string NonStaticMethod() { return MyNewClass.MyStringMethod(); //Cannot call non static method } } class MyNewClass { public string MyStringMethod() { return "method called"; } } I get the error: Cannot access non-static method "MyStringMethod" in a static

问题 How can i know when my C# console application will be stopping? Is there any event or like that? Thanks! 回答1: Use ProcessExit event of the application domain class Program { static void Main(string[] args) { AppDomain.CurrentDomain.ProcessExit += new EventHandler(CurrentDomain_ProcessExit); } static void CurrentDomain_ProcessExit(object sender, EventArgs e) { Console.WriteLine("exit"); } } 回答2: Handling the event System.Console.CancelKeyPress might help you.
