问题 I'm trying to compare two Actions. The comparison with == always returns false as does the Equals-method even though it's the same instance. My question is: Is it really not possible or am I doing it wrong? Cheers AC 回答1: You are doing it wrong. If I am to believe you, when you say "even though it's the same instance", then the following code executed through LINQPad tells me that you must be doing something wrong, or the "same instance" is incorrect: void Main() { Action a = () => Debug

问题 Here is my C# code snippet: if (Environment.IsWindows) { _sessionAddress = GetSessionBusAddressFromSharedMemory(); } ... [System.Runtime.Versioning.SupportedOSPlatform("windows")] private static string GetSessionBusAddressFromSharedMemory() { ... } When I run the build, I get an error: error CA1416: 'GetSessionBusAddressFromSharedMemory()' is supported on 'windows' My logic is to invoke the method only when I am on Windows. How do I turn this warning off when building on Ubuntu? Regards. 回答1:

问题 I'm using Microsoft.Azure.ServiceBus . (doc) I was getting an exception of: The lock supplied is invalid. Either the lock expired, or the message has already been removed from the queue. By the help of these questions: 1, 2, 3, I am able to avoid the Exception by setting the AutoComplete to false and by increment the Azure's queue lock duration to its max (from 30 seconds to 5 minutes). _queueClient.RegisterMessageHandler(ProcessMessagesAsync, new MessageHandlerOptions

问题 Quick little question... I need to count the length of a string, but WITHOUT the spaces inside of it. E.g. for a string like "I am Bob", string.Length would return 8 (6 letters + 2 spaces). I need a method, or something, to give me the length (or number of) just the letters (6 in the case of "I am Bob") I have tried the following s.Replace (" ", ""); s.Replace (" ", null); s.Replace (" ", string.empty); to try and get "IamBob", which I did, but it didn't solve my problem because it still

问题 Attempting to make a protected internal member of a protected internal class within a public class results with the following issue: Inconsistent accessibility: field type 'what.Class1.ProtectedInternalClass' is less accessible than field 'what.Class1.SomeDataProvider.data' The accessibility should be equivalent, as far as I know. Where am I mistaken? Origination class: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace what { public class Class1 {
