问题 I have this C# code and I want it to trigger every minute. private void MyFunction() { if (DateTime.Now.Hour == 6 && ranalarm == false) { ranalarm = true; Event(); } else if (DateTime.Now.Hour != 6 && ranalarm == true) { ranalarm = false; } } How can I make function MyFunction() trigger every minute in C#? I tried working with timers but Visual Studio said it conflicted with my System.Windows.Forms . 回答1: You can use System.Threading.Timer and TimeSpan. Something like this: TimeSpan start =

问题 I am trying to pass bytes by reference from C# such that I can call the atomic operation InterlockedOr8 on them. I have the following static library in C++: Bitwise.h : char EightBitOr(char volatile* destination, char value); Bitwise.cpp : #include "Bitwise.h" char EightBitOr(char volatile* destination, char value) { return InterlockedOr8(destination, value); } I am calling it from this C++/CLI wrapper DLL: Wrapper.h : #include "..\Bitwise\Bitwise.h" using namespace System; namespace Wrapper

问题 When reading a CSV into a DataTable, I am trying to add options for boolean and null values that don't seem to be working. For example, a file containing data similar to: Id,MaxDiscount,Name,Active,AltId 1,,Foo,1,ABC123 2,10,Bar,0,DEF345 And the following logic that uses a schema file to dynamically get the headers and data types we are expecting: var dt = new DataTable(); using (var reader = new StreamReader(file.FullName)) using (var csv = new CsvReader(reader)) { csv.Configuration

问题 Hey awesome Stackoverflow people I am currently evaluating if we should use iText 7.1.9 for Java or C#. To do this, I created a test case where I write a single PDF with a bunch of pages, each containing a big table (code below). In Java, creating a PDF with x pages yields the following results: 1 page: 0 sec 10 pages: 1 sec 100 pages: 5 sec 1000 pages: 23 sec This is reasonably performant. However, when I ported the exact same code to C# .Net, I got quite the shock: 1 page: 0 sec 10 pages: 1

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
