sorting based on previous sorts

I'm trying to sort a list of IDs based on a "sorting map" which is an array of (ID1, ID2, timestamp) tuples that determines which IDs should be sorted before other IDs. Here are the rules: ID1 should be sorted before ID2 . the timestamp can be used to break ties with newer timestamps beating older timestamps. eg given sorting key (C, A, 1/1/1900), (C, B, 1/1/2000) then B is so

根据以前的排序进行排序

我试图根据“排序映射”对ID列表进行排序,排列映射是一个(ID1, ID2, timestamp)元组数组,它​​确定哪些ID应在其他ID之前排序。 这是规则: ID1应在ID2之前排序。 时间戳可以用来打破较新时间戳与较旧时间戳的关系。 例如给定的排序键(C, A, 1/1/1900), (C, B, 1/1/2000)则B在A之前排序。 (A, B, 1/1/1950), (B, C, 1/1/1980), (C, A, 1/1/1900) 。 时间戳可以用来中断循环,在循环中删除旧时间戳的记录,直到循环消失

Entity Framework with Instead Of triggers

I am using EF with a SQL Server database. I created a view and an Instead Of Insert trigger for that view which looks like this: insert into Target (value, someFk) select value, 4 from inserted select id from Target where @@ROWCOUNT > 0 and id = scope_identity() I mapped the view into an EF edmx. When I try to add an entity I get the following exception when I call SaveChanges() : Unab

我正在使用EF与SQL Server数据库。 我为该视图创建了一个视图和一个“ Instead Of Insert触发器,如下所示: insert into Target (value, someFk) select value, 4 from inserted select id from Target where @@ROWCOUNT > 0 and id = scope_identity() 我将视图映射到EF edmx。 当我尝试添加实体时,在调用SaveChanges()时出现以下异常: 无法更新EntitySet'TargetView',因为它具有DefiningQuery并且元素中

Where is SqliteDataReader in sqlite

I'm trying to port an iOS application that uses native Sqlite3 and makes heavy use of SqliteDataReader . On the target platform I use SQLIte-Net (https://github.com/praeclarum/sqlite-net) and there the SqliteDataReader class does not exist. What are my best options to convert this? The usage of the reader is always code like this: SqliteConnection oConn = AppDelegateBase.MasterDatabase.Cr

SqliteDataReader在sqlite中的位置

我试图移植使用本机Sqlite3的iOS应用程序,并大量使用SqliteDataReader 。 在目标平台上,我使用SQLIte-Net(https://github.com/praeclarum/sqlite-net),那里的SqliteDataReader类不存在。 我最好的选择是什么将其转换? 阅读器的使用总是这样的代码: SqliteConnection oConn = AppDelegateBase.MasterDatabase.CreateDBMSConnection(); using ( SqliteCommand oCmd = new SqliteCommand ( "SELECT * FROM ATable"), oCon

C# locks and newbie multithreading questions

Some newbie questions about multi-threading in .NET which I think will help reinforce some concepts I'm trying to absorb - I've read several multi-threading material (including the Albahari ebook) but feel I just need some confirmation of some questions to help drive these concepts home A lock scope protects a shared region of code - suppose there is a thread executing a method that inc

C#锁和新手多线程问题

一些关于.NET中多线程的新手问题,我认为这将有助于强化我想吸收的一些概念 - 我已经阅读了几种多线程材料(包括Albahari电子书),但觉得我只需要一些问题的确认帮助将这些概念推向家庭 锁范围保护共享代码区域 - 假设有一个线程正在执行一个方法,该方法会在循环中增加一个简单的整数变量x - 但是,这不会保护其他地方的代码,这些代码也可能会改变变量x,例如另一个线程上的另一个方法... 由于这是潜在影响同一个变量的

How to identify speaker from voice pattern using Microsoft Speech?

I'm using Microsoft Speech C# API for Home Automation commands I'd like to know if there is a way or built-in C# method to hash Voice Input and recognize who's speaking.

Looking for a modern comparison between ASP.NET MVC and MonoRail

I'm coming from Ruby on Rails, and I need to create a C# web application. Currently I'm looking at ASP.NET MVC and MonoRail. Most of the comparisons I find are from 2008-2009, when ASP.NET MVC was still new, and most of the points against MVC was that it's too raw, not nearly as refined as MonoRail. Well, several years have past since then, and Microsoft did alot of work on ASP.NE

寻找ASP.NET MVC和MonoRail之间的现代比较

我来自Ruby on Rails,我需要创建一个C#Web应用程序。 目前我在看ASP.NET MVC和MonoRail。 我发现大多数比较是从2008-2009年开始的,当时ASP.NET MVC还是新的,而且大部分反对MVC的观点都认为它太过原始,并不像MonoRail那样精致。 那么,从那以后几年过去了,微软在ASP.NET MVC上做了很多工作。 两个框架的现代版本如何相互比较? 我大约四年前评估过MonoRail,与今天的mvc3相比,这些是主要差异(imho) Razor作为MV

Why does ICollection not contain an Add method?

As in the title, does anyone know why the ICollection interface does not contain an Add method? It seems very odd that the generic version, ICollection<T> , has an Add but ICollection does not. Anyone with deeper knowledge on this would be really helpful. As to why I care- unfortunately the developers who build SharePoint have never learned about generics, so every single collection in

为什么ICollection不包含Add方法?

在标题中,有没有人知道为什么ICollection接口不包含Add方法? 似乎很奇怪的是,通用版本ICollection<T>具有Add但ICollection不具有。 任何对此有深入了解的人都会很有帮助。 至于我为什么关心 - 不幸的是,构建SharePoint的开发人员从未学过泛型,因此API中的每个集合都是基于ICollection非泛型集合。 我想附加几个扩展方法ICollection ,其中包括添加到集合,但这似乎是不可能的(至少不可能没有反思)。 编辑:

Implementing SSH Server in C#/.Net

A project we're working on just got a new requirement added to it: it has to be able to receive files through SFTP (SSH) using key/pair authentication. We've been able to find an interesting collection of SSH client libraries (such as SSH.Net), but no server ones. The closest we've found so far is a Python library that we're debating implementing through IronPython. How should

在C#/ .Net中实现SSH服务器

我们正在开发的一个项目刚刚获得了新的要求:它必须能够通过使用密钥/对认证的SFTP(SSH)接收文件。 我们已经能够找到一组有趣的SSH 客户端库(如SSH.Net),但没有找到服务器库。 到目前为止,我们发现的最接近的是一个Python库,我们正在通过IronPython进行辩论。 我们应该如何去做这件事? 我们是否缺少任何图书馆,还是应该自己实施? 在google上快速搜索“.NET SSH服务器”,可以看到我们的SecureBlackbox在第四位。
