ILogger.Log method declaringType parameter

When I wanted to use the different logging levels available with log4net, I found out that I needed to use the method ILogger.Log, which looks like this: void Log(Type callerStackBoundaryDeclaringType, Level level, object message, Exception exception); We can get an ILogger reference from our usual ILog reference to call this method and it is usually suggested to wrap this call in an extension

ILogger.Log方法declaringType参数

当我想使用log4net提供的不同日志级别时,我发现我需要使用ILogger.Log方法,它看起来像这样: void Log(Type callerStackBoundaryDeclaringType, Level level, object message, Exception exception); 我们可以从我们通常的ILog引用中获得一个ILogger引用来调用此方法,并且通常建议将此调用包装为扩展方法。 我们得到的是以下内容: //typical log4net ILog reference private static readonly ILog Logger = LogManager.Ge

How to use Serilog with Unity?

recencely i discoverd serilog ( structured logging for .net ) and saw a lot of its advantages. but i face some problems with it . i have 4 projects, one is web, one is infrastructure and the other two are windows services, i want to declare serilog configuration once and use it multiple times. and also i want to use it with dependency injection. i have been searching web for three days now ,

如何使用Serilog和Unity?

最后我发现了serilog(对.net的结构化记录)并看到了它的很多优点。 但我遇到了一些问题。 我有4个项目,一个是web,一个是基础设施,另外两个是windows服务,我想宣布serilog配置一次并多次使用它。 我也想用它来依赖注入。 我一直在网上搜索了三天,但我没有发现任何有用的东西,请有人帮助我。 比如我想让这个类成为我的日志类。 public interface IMyLogger { void Information(string message, object[] paramete

How do I add a reference to an unmanaged C++ project called by a C# project?

One solution (the.sln) One C++ project (mycppproject.vcxproj in 2010or mycppproject.vcproj in 2008) which compiles a native DLL exporting some function(s). In debug this builds c:outputDebugmycppproject_d.dll and in release this builds c:outputReleasemycppproject.dll. One C# console application (mycsharpconsole.csproj) containing PInvoke calls into the DLL. All compiles fine. When I buil

如何添加对C#项目调用的非托管C ++项目的引用?

一个解决方案(the.sln) 一个C ++项目(2010年的mycppproject.vcxproj或2008年的mycppproject.vcproj),它编译导出一些函数的本机DLL。 在调试时,这会生成c: output Debug mycppproject_d.dll,并且在发布版本中会生成c: output Release mycppproject.dll。 包含PInvoke调用的一个C#控制台应用程序(mycsharpconsole.csproj)调用到DLL中。 所有编译都很好。 当我编译时,我希望能够将csharp项目的引用添加到

Is C# really slower than say C++?

I've been wondering about this issue for a while now. Of course there are things in C# that aren't optimized for speed, so using those objects or language tweaks (like LinQ) may cause the code to be slower. But if you don't use any of those tweaks, but just compare the same pieces of code in C# and C++ (It's easy to translate one to another). Will it really be that much slowe

C#真的比说C ++慢吗?

我一直在想这个问题一段时间了。 当然,C#中的某些东西并未针对速度进行优化,因此使用这些对象或语言调整(如LinQ)可能会导致代码变慢。 但是,如果您不使用任何这些调整,只是比较C#和C ++中的相同代码片段(很容易将其转换为另一个)。 它真的会慢得多吗? 我看过一些比较表明C#在某些情况下可能会更快,因为理论上JIT编译器应该实时优化代码并获得更好的结果: 托管还是非托管? 我们应该记住,JIT编译器会实

printf slows down my program

I have a small C program to calculate hashes (for hash tables). The code looks quite clean I hope, but there's something unrelated to it that's bugging me. I can easily generate about one million hashes in about 0.2-0.3 seconds (benchmarked with /usr/bin/time). However, when I'm printf()inging them in the for loop, the program slows down to about 5 seconds. Why is this? How to

printf减慢我的程序

我有一个小型的C程序来计算哈希(对于哈希表)。 我希望代码看起来很干净,但有一些与我无关的东西无关。 我可以在大约0.2-0.3秒内轻松生成约一百万个哈希(以/ usr / bin / time为基准)。 但是,当我将printf()放入for循环时,程序会减速到大约5秒钟。 为什么是这样? 如何让它更快? mmapp()ing stdout也许? stdlibc是如何为此设计的,以及如何改进? 内核如何支持它更好? 如何修改它以使本地“文件”(套

C++ performance vs. Java/C#

My understanding is that C/C++ produces native code to run on a particular machine architecture. Conversely, languages like Java and C# run on top of a virtual machine which abstracts away the native architecture. Logically it would seem impossible for Java or C# to match the speed of C++ because of this intermediate step, however I've been told that the latest compilers ("hot spot&quo

C ++性能与Java / C#

我的理解是C / C ++生成本地代码以在特定的机器体系结构上运行。 相反,像Java和C#这样的语言运行在虚拟机的顶部,虚拟机抽象出本地体系结构。 从逻辑上讲,Java或C#似乎不可能匹配C ++的速度,因为这个中间步骤,然而我被告知最新的编译器(“热点”)可以达到这个速度甚至超过它。 也许这更像是一个编译问题,而不是一个语言问题,但任何人都可以用简单的英语解释这些虚拟机语言之一是否可能比本地语言执行得更好? 一般

MVC5 and EF6.1.3 Scaffolding problems

I have a problem when trying to build a view using scaffolding via the "Add View" function within a controller using MVC5 with Entity Framework 6.1.3 . However, using Entity Framework 5.0.0 everything works perfectly ~ I can build a view successfully. Using Entity Framework 6.1.3 When I select the "Add View" function I get the following error " There was an error

在使用实体框架6.1.3使用MVC5的控制器中通过“添加视图”功能使用脚手架构建视图时遇到问题。 但是,使用Entity Framework 5.0.0一切正常 - 我可以成功构建视图。 使用实体框架6.1.3 当我选择“添加视图”功能时,出现以下错误 “ 运行选定的代码生成器时发生错误'无法检索'xxx'的元数据。找不到'xxx'的CLR类型 。 我的环境是VS2013 Ultimate(Update4),目标框架4.5.1,C#,MVC5,EF6.1.3 Database

On Linux, is TLS set up by the kernel or by libc (or other language runtime)?

I'm just studying how TLS (thread-local storage) is implemented on Linux systems. The document ELF Handling for Thread-Local Storage explains how a program's requirements for thread-local variables can be encoded in an ELF binary, and how the "runtime" should handle such binaries. However, it's not clear to me whether in practice the "runtime" which sets up the

在Linux上,是由内核还是由libc(或其他语言运行库)设置TLS?

我只是研究如何在Linux系统上实现TLS(线程本地存储)。 文档ELF用于线程本地存储的处理解释了如何将程序对线程局部变量的需求编码到ELF二进制文件中,以及“运行时”如何处理这些二进制文件。 然而,我不清楚在实际中,设置TLS区域的“运行时”是Linux内核(以及它的用于加载ELF二进制文件的代码)还是libc中的一些初始化代码。 有人可以简单解释吗? (背景:我试图静态链接并运行一个应用程序,但它在启动时发生段错误,在g

SQL Query Using Entity Framework Runs Slower, uses bad query plan

am using entity framework generally successfully, but one query is running remarkably slowly. The query (generated by EF) is as follows: exec sp_executesql N'SELECT [Project1].[downtimeId] AS [downtimeId], CASE WHEN ([Extent12].[downtimeStart] > @p__linq__7) THEN [Extent13].[downtimeStart] ELSE @p__linq__8 END AS [C1], CASE WHEN ([Extent14].[equipmentID] IS NULL) THEN 0 ELSE [Extent15].[e

SQL查询使用实体框架运行速度较慢,使用错误的查询计划

我通常使用实体框架成功,但一个查询运行速度非常缓慢。 查询(由EF生成)如下所示: exec sp_executesql N'SELECT [Project1].[downtimeId] AS [downtimeId], CASE WHEN ([Extent12].[downtimeStart] > @p__linq__7) THEN [Extent13].[downtimeStart] ELSE @p__linq__8 END AS [C1], CASE WHEN ([Extent14].[equipmentID] IS NULL) THEN 0 ELSE [Extent15].[equipmentID] END AS [C2], CASE WHEN ([Extent16].[equipmen

What is really happening on removing and adding white space characters?

I'm new in programming and learning basics of C programming. I'm learning about how scanf() works but I think now I'm very much confused and really don't know how and what to ask. But I will try my best to put my question clear. Questions I'm really not able to understand the whole concept of whitespace. I mean when they are skip by the scanf and when they are not and b

删除和添加空格字符真的发生了什么?

我是编程和学习C编程基础的新手。 我正在学习scanf()工作方式,但我现在觉得我非常困惑,真的不知道如何以及要问什么。 但我会尽我所能把我的问题清楚。 问题 我真的不能理解空白的整个概念。 我的意思是当他们跳过scanf时,他们什么时候没有,也是最大的问题: 他们如何被跳过? 除了空白概念,我还无法理解scanf函数的工作scanf吗? 我曾在很多书籍和网站以及本网站上阅读过这方面的内容,但它让我更加困惑,因为每
