I need to do this kind of work: Get Page object from database For each page get all images and process them (IO bound, for example, upload to CDN) If all images proceeded successfully then mark Page as processed in database Since I need to control how much Pages I process in parallel I've decided to go with TPL Dataflows: ____________________________ | Data pipe | |
我需要做这样的工作: 从数据库中获取页面对象 对于每个页面,获取所有图像并处理它们(IO限制,例如上传到CDN) 如果所有图像都成功处理,则将页面标记为在数据库中处理 由于我需要控制并行处理的页数,因此我决定使用TPL数据流: ____________________________ | Data pipe | | BufferBlock<Page> | | BoundedCapacity = 1 | |____________________________| |
Hi i am using the transaction-per-request (session-in-view) pattern for an asp.net web application. I have a couple of points in the application where i want to Save an NHibernate managed entity and then do a couple of more inserts and updates using common sql. These inserts/updates depend on the ID that the NH saved entity will take. The problem is that the generated id does not exist in the
您好,我正在使用asp.net web应用程序的事务处理每个请求(会话在视图中)模式。 我在应用程序中有几点要保存一个NHibernate管理实体,然后使用普通的SQL做更多的插入和更新。 这些插入/更新取决于NH保存实体将采用的ID。 问题是生成的id不存在于事务的范围中。 如果我强制刷新/提交该ID是持久的,但如果插入/更新失败,我必须回滚,但刷新/提交的实体不会。 目前,我正在为这些案例进行手动插入,但这是我想要更改的内容
I am working with a third party API that uses .NET 4 . I would like to use Async/Await features in my class library. I installed Microsoft.Bcl.Async from NuGet. I have a few questions regarding deployment: 1) Upon installing Microsoft.Bcl.Async , I have a number of references added to my project ( Microsoft.Threading.Tasks , Microsoft.Threading.Tasks.Extensions ..). Also there is an app.con
我正在使用使用.NET 4第三方API。 我想在我的类库中使用Async / Await功能。 我从NuGet安装了Microsoft.Bcl.Async 。 我有几个关于部署的问题: 1)在安装Microsoft.Bcl.Async ,我添加了许多引用( Microsoft.Threading.Tasks , Microsoft.Threading.Tasks.Extensions ..)。 还有一个创建的app.config文件。 部署要求是什么? 2)我将如何为第三方应用程序安装目录中的类库部署app.config文件。 我是否需要将app.co
Which is more "appropriate" when writing a linux kernel module: Using static const to define a constant, or #define ? I have a kernel module related to a piece of hardware, and I have a typical constant that's the number of buffers. Rather than hard-code "3" everywhere, I want to use a constant. C style usually recommends taking static const , but I notice the Kernel i
编写一个linux内核模块时,哪一个更“适合”:使用static const来定义一个常量,还是#define ? 我有一个与硬件相关的内核模块,我有一个典型的常量,就是缓冲区的数量。 我不想在任何地方硬编码“3”,我想使用常量。 C风格通常建议采用static const ,但我注意到Kernel充满了#define的各处。 有理由吗? 它曾经是你无法做到的: const size_t buffer_size = 1024; unsigned char buffer[buffer_size]; 在C中,因为buffer_
I'm trying to obfuscate a .net project with eazfuscator.net. The problem is that, when I decompile it using .NET Reflector you can see to much of the code. All the private members are obfuscated, but the public members give to much information about the program. Is it possible to also obfuscate the public members of my library? I know that this isn't done by the program because the p
我试图用eazfuscator.net混淆一个.net项目。 问题是,当我使用.NET Reflector对其进行反编译时,您可以看到很多代码。 所有私人成员都被混淆了,但公众成员提供了有关该计划的许多信息。 是否有可能混淆我的图书馆的公众成员? 我知道这不是由程序完成的,因为公共成员通常是从其他程序集访问的。 但是难道不应该混淆整个解决方案,以便其他程序集的访问也可以从该工具重命名? 我已经尝试使用ObfuscationAttribute [ass
We're working on a new ASP.NET MVC 4.1 app. We're hooking up the ASP.NET Identity stuff, and we're struggling with tokens for password reset and new invite. I can't seem to find a way to set the expiration time for the tokens that are generated, and it seems to be set at around 10 mins by default. We're using a EmailTokenProvider as the user token provider, because it seems
我们正在研究一个新的ASP.NET MVC 4.1应用程序。 我们正在关注ASP.NET身份,我们正在努力使用令牌来重置密码和新邀请。 我似乎无法找到一种方法来设置生成的令牌的到期时间,并且它似乎默认设置为大约10分钟。 我们使用EmailTokenProvider作为用户令牌提供程序,因为它似乎与用户的安全印记一起工作良好。 我们如何设置令牌的到期时间 - 理想情况下,我们希望为邀请对重置密码令牌进行不同的设置。 我们的用户管理器如下
I am processing a TreeView of directories and files. A user can select either a file or a directory and then do something with it. This requires me to have a method which performs different actions based on the user's selection. At the moment I am doing something like this to determine whether the path is a file or a directory: bool bIsFile = false; bool bIsDirectory = false; try {
我正在处理目录和文件的TreeView 。 用户可以选择一个文件或一个目录,然后用它做一些事情。 这要求我有一种方法可以根据用户的选择执行不同的操作。 目前我正在做这样的事情来确定路径是文件还是目录: bool bIsFile = false; bool bIsDirectory = false; try { string[] subfolders = Directory.GetDirectories(strFilePath); bIsDirectory = true; bIsFile = false; } catch(System.IO.IOException) {
I have a list of numbers, and I need to create every possible unique combination of the numbers in the list, without repeats, using a LINQ query. So, for example, if I have { 1, 2, 3 } , the combinations would be 1-2 , 1-3 , and 2-3 . I currently use two for loops, like so: for (int i = 0; i < slotIds.Count; i++) { for (int j = i + 1; j < slotIds.Count; j++) { Expression
我有一个数字列表,我需要使用LINQ查询来创建列表中所有可能的数字组合,而不需要重复。 因此,例如,如果我有{ 1, 2, 3 }中,所述组合将是1-2 , 1-3 ,和2-3 。 我目前使用两个for循环,如下所示: for (int i = 0; i < slotIds.Count; i++) { for (int j = i + 1; j < slotIds.Count; j++) { ExpressionInfo info1 = _expressions[i]; ExpressionInfo info2 = _expressions[j]; //
This question already has an answer here: Is casting the same thing as converting? 12 answers I believe what Eric is trying to say is: Casting is a term describing syntax (hence the Syntactic meaning). Conversion is a term describing what actions are actually taken behind the scenes (and thus the Semantic meaning). A cast-expression is used to convert explicitly an expression to a give
这个问题在这里已经有了答案: 转换与转换相同的东西吗? 12个答案 我相信Eric想说的是: 铸造是描述句法的术语(因此是句法意义)。 转换是一个术语,用于描述幕后实际采取的行动(以及因此的语义含义)。 cast-expression用于将表达式显式转换为给定类型。 和 形式(T)E的强制表达式(其中T是类型并且E是一元表达式)执行E的值到T的显式转换(第13.2节)。 似乎通过说语法中的转换操作符执行显式转换来支持
We're often told we should protect encapsulation by making getter and setter methods (properties in C#) for class fields, instead of exposing the fields to the outside world. But there are many times when a field is just there to hold a value and doesn't require any computation to get or set. For these we would all do this number: public class Book { private string _title; pu
我们经常被告知我们应该通过为类字段创建getter和setter方法(C#中的属性)来保护封装,而不是将字段暴露给外部世界。 但是有很多时候,一个字段只是在那里保存一个值,并且不需要任何计算来获取或设置。 对于这些我们都会做这个数字: public class Book { private string _title; public string Title { get{ return _title; } set{ _title = value; } } } 那么,我有一个坦白的
