Reactive Extensions: buffer until subscriber is idle

I have a program where I'm receiving events and want to process them in batches, so that all items that come in while I'm processing the current batch will appear in the next batch. The simple TimeSpan and count based Buffer methods in Rx will give me multiple batches of items instead of giving me one big batch of everything that has come in (in cases when the subscriber takes longer th

反应式扩展:缓冲直到用户闲置

我有一个程序,我正在接收事件并希望分批处理它们,以便在处理当前批次时进入的所有项目都将显示在下一批次中。 Rx中简单的TimeSpan和基于计数的Buffer方法会给我多批次的物品,而不是给我一大堆所有进来的物品(如果订户的时间超过了指定的TimeSpan或超过N个物品进入, N大于计数)。 我研究了使用Func <IObservable <TBufferClosing >>或IObservable <TBufferOpening>和Func <TBufferOpening,IObser

log4net Adonet Appender Connection Issue

I have developed a windows service in which I am using a timer control to perform some scheduled tasks. The timer elapse event occurs every 5 minutes in which a log entry is made using log4net appender to Oracle database. All works fine until the DB Server closes all connections for nightly cold backup. Since that time all logs in DB are missed and nothing is logged unless service is restarte

log4net Adonet Appender连接问题

我开发了一个Windows服务,我正在使用一个计时器控件来执行一些计划任务。 定时器过期事件每5分钟发生一次,其中使用log4net appender向Oracle数据库创建日志条目。 所有工作都正常,直到数据库服务器关闭夜间冷备份的所有连接。 从那时起,所有DB中的日志都会丢失,并且不记录任何内容,除非服务重新启动,即使备份过程少于30分钟。 从其他帖子我发现,log4net只使用一个连接,如果丢失,则所有后续日志都将被丢弃。 为

.Net assembly adds superfluous AND when setting bool to TRUE?

The following code written in C# in VS2010 for .Net 4.0: bool b = false; has the following disassembly: XOR EDX,EDX MOV DWORD PTR[EBP-3Ch],EDX which makes perfect sense. However, the following code: bool b = true; has the following disassembly: MOV EAX,1 AND EAX,0FFh MOV DWORD PTR[EBP-3Ch],EAX What is the purpose of the AND operation? Why not just MOV EAX,1 ? Line | EAX -----------

当将bool设置为TRUE时,.Net程序集会添加多余的AND?

在VS2010中用.NET编写的以下代码: bool b = false; 有以下拆卸: XOR EDX,EDX MOV DWORD PTR[EBP-3Ch],EDX 这很有道理。 但是,下面的代码: bool b = true; 有以下拆卸: MOV EAX,1 AND EAX,0FFh MOV DWORD PTR[EBP-3Ch],EAX AND操作的目的是什么? 为什么不只是MOV EAX,1 ? Line | EAX ----------- 1 | 0x01 2 | 0x01 & 0xFF = 0x01 3 | 0xFF 我怀疑and 0xff是截断到8位布尔。 我不太了解内部结

Manual creation of strings resource file not working with Application

I am working on a project where localised strings are to be inserted later into the live ASP.NET (MVC4) site/application. The way we plan to achieve this (for validation messages etc.) is to obtain the strings from the clients, put them in a .resx file, compile this .resx file into a .resources file and then into a .dll. Finally this .dll is placed in the relevant language folder on the live si

手动创建不适用于应用程序的字符串资源文件

我正在开发一个项目,其中本地化的字符串稍后将被插入到实时ASP.NET(MVC4)站点/应用程序中。 我们计划实现此目的的方式(用于验证消息等)是从客户端获取字符串,将其放入.resx文件中,将此.resx文件编译为.resources文件,然后编译为.dll文件。 最后,将这个.dll文件放在现场的相关语言文件夹中。 但是,该手动创建的.dll不被应用程序拾取。 相反,它会回落到默认语言.dll。 另一方面,如果.resx文件是通过Visual Studio

Can C#/.net parse exponential hex encoded floating point numbers from strings?

C++, Java all include the [-]0xh.hhhhp+/-d format in the syntax of the language, other languages like python and C99 have library support for parsing these strings (float.fromhex, scanf). I have not, yet, found a way to parse this exact hex encoded exponential format in C# or using the .NET libraries. Is there a good way to handle this, or a decent alternative encoding? (decimal encoding is

C#/ .net可以从字符串中解析指数十六进制编码的浮点数吗?

C ++,Java都在语言的语法中包含[ - ] 0xh.hhhhp +/- d格式,其他语言(如python和C99)也支持解析这些字符串(float.fromhex,scanf)。 我还没有找到一种在C#中使用.NET库解析这个精确的十六进制编码指数格式的方法。 有没有一种好的方法来处理这个问题,还是一个体面的替代编码? (十进制编码不准确)。 示例字符串:0x1p-8 -0xfe8p-12 谢谢 不幸的是,我不知道任何内置于.NET的方法与Python的float.fromhex()

Writing an extremely simple parser

I'm writing a very basic web server that has to support an extremely limited special server side scripting language. Basically all I need to support is "echo", addition/subtraction/multiplication (no division) with only 2 operands, a simple "date()" function that outputs the date and the use of the "&" operator to concatenate strings. An example could be:

编写一个非常简单的解析器

我正在编写一个非常基本的Web服务器,它必须支持极其有限的特殊服务器端脚本语言。 基本上所有我需要支持的是“回声”,只有2个操作数的加/减/乘(没有除法),一个简单的“date()”函数输出日期和使用“&”运算符串接字符串。 一个例子可能是: echo "Here is the date: " & date(); echo "9 x 15 = : & 9*15; 我已经完成并创建了生成令牌所需的代码,但我不确定我是否使用了权限令牌。 我为以下内容创建了令牌: E

Console.Writeline working on x86 but not x64

I'm testing a project in visual studio 2012. When I run my code in x86, Console.Writeline shows up in the output window. However, when I run it in x64, it does not. I understand I can use System.Diagnostics.Debug instead, but I would really like to understand why Console.Writeline is not working, or if there is a setting somewhere. Thanks. Edit: An observation: The Visual Studio host

Console.Writeline在x86上工作,但不能在x64上工作

我在visual studio 2012中测试一个项目。 当我在x86中运行我的代码时, Console.Writeline显示在输出窗口中。 但是,当我在x64中运行它时,它不会。 我知道我可以使用System.Diagnostics.Debug来代替,但我真的很想理解为什么Console.Writeline无法正常工作,或者某个地方有设置。 谢谢。 编辑:观察:两个版本的Visual Studio宿主进程都被禁用。 当我启用它时,所有Console.Writeline消息都显示为x64和x86。 当我再

How to use Ninject across assemblies

I can see that similar questions has been asked previously, but being totally new to DI and .Net I am not able to grasps the entire solution or may not have found the right source.... I have assemblies WebAPI,BL,DL. WebAPI is dependent on BL, BL is dependent on DL, WebAPI DOES NOT reference DL and I would like to keep it the same. There are few more assemblies but this is sufficient to i

如何在组件中使用Ninject

我可以看到类似的问题之前已经被问到过,但是对于DI和.Net来说我完全陌生,我无法掌握整个解决方案,或者可能找不到合适的源代码.... 我有程序集WebAPI,BL,DL。 WebAPI依赖于BL, BL依赖于DL, WebAPI不引用DL,我希望保持不变。 有更多的程序集,但这足以说明问题。 WebAPI具有应用程序开始部分,因此我可以使用它来初始化Ninject内核并为WebAPI项目注册依赖项。 我怎样才能达到BL和其他议会的相同? 有几种不

Is it possible to create System.Int32 in C#?

If you get under the hood, value types in C# are treated very specially by compiler/CLR. But types internal to CLR are treated even more specially. Here is what I mean: int a = 5; int b = 10; int с = a + b; a.CompareTo(b); You can hover with your mouse over int in Visual Studio and see that actually it is System.Int32 struct. That's OK. Now you can grab ILDasm and look into what System.

是否有可能在C#中创建System.Int32?

如果你深入了解C#中的值类型,那么编译器/ CLR会非常特别地处理这些值。 但CLR内部的类型更加特殊。 这是我的意思: int a = 5; int b = 10; int с = a + b; a.CompareTo(b); 您可以将鼠标悬停在Visual Studio中的int ,然后看到它实际上是System.Int32结构体。 没关系。 现在,您可以获取ILDasm并查看System.Int32是什么:返回它是非常简单的结构,它具有一个int32类型的字段(这是CLR内部的int32 ),并且没有重载操作
