system.diagnostics

问题 I've been searching and experimenting for a while with this, but I have had no luck. I am trying to make a console program to automate some tasks that I couldn't quite do with a BAT file. I want to call "signcode.exe" from the Windows SDK, the bin folder with all the tools in my system PATH, and I can call "signcode" from anywhere, but Process.Start is ignoring the path. Current code: System.Diagnostics.Process sign = new System.Diagnostics.Process(); sign.StartInfo.FileName = signCommand

问题 Coming from my "answer" to question "Stopwatch in a Task seems to be additive across all tasks, want to measure just task interval" What are the possible differences between creating a new Stopwatch instance as: Stopwatch timer = System.Diagnostics.Stopwatch.StartNew(); with Stopwatch timer = new Stopwatch(); timer.Start(); Implied subquestion: Why was StartNew() method provided? 回答1: StartNew , create new instance of the stop watch and starts it as well. Simple new is Stopwatch instantiation

问题 We've created a Windows 10 application that runs on tablets in Windows 10 kiosk mode. It works just fine, however, the wifi connection gets lost sometimes since the locations are very remote. We tried fixing the issue from the networking side, but when the devices lose and regain internet access the application will still hang as if it doesn't have internet access displaying a blank page. Where these devices are used, they are bolted into the wall to prevent theft. Which means if we want to

问题 Anyone knows the difference between System.Diagnostic.Trace and System.Diagnostic.TraceSource classes? I've been using Trace for most of my projects and I just happen to found out about TraceSource the other day. They seems to offer similar API, is one better than the other? 回答1: TraceSource is the newer version (since .NET 2) and Trace is the older version, more info is available here: Clarification on TraceSource/Trace 回答2: TraceSource allows you to enhance the granularity over your tracing

问题 I've been trying to work with ETW in .net 4.0. I have started using Microsoft EventSource Library 1.0.4-beta (https://www.nuget.org/packages/Microsoft.Diagnostics.Tracing.EventSource) Here is the code i written for generating events for my application. [EventSource(Name = "Samples-EventSourceDemos-EventSourceLogger")] public sealed class EventSourceLogger : EventSource { public static EventSourceLogger Log = new EventSourceLogger(); public static string GetManifest() { return GenerateManifest

问题 I don't know why, but many computers hangs on following operation: void Init() { net1 = new List<PerformanceCounter>(); net2 = new List<PerformanceCounter>(); foreach (string instance in new PerformanceCounterCategory("Network Interface").GetInstanceNames()) { net1.Add(new PerformanceCounter("Network Interface", "Bytes Received/sec", instance)); net2.Add(new PerformanceCounter("Network Interface", "Bytes Sent/sec", instance)); } } //Once in 1 second void UpdateStats() { Status.Text = ""; for

问题 I'm using C#'s System.Diagnostic.Process object. One of its properties is Id . The Id this produces is not the same as the PID , shown in Windows Task Manager . Why is this? You see, once this process is started. It launches two other unmanaged processes, for which I can't explicitly get IDs for by object property references. I have to search through all processes to find them by process name via System.Diagnostics.Process.GetProcesses() . I'm trying to find a reliable way to kill this

问题 We already know how System.Diagnostics.Process.Start("C:\filename.png") works, but what if the file name doesn't end with an extension? How can I run a filename without an extension, using the default program that is associated with, for example, a .png extension? Something like: openFile("C:\filename","PNG") 回答1: You can of course patch together the FileName and the Extension and hope for the best. Or test whether a file Extension has a predefined Opener, an entry in the Registry that
