In writing an application that runs on Fluent Nhibernate/Nhibernate, something has me a bit concerned. I suppose this would be true of any ORM (and even without using an ORM), but what is the ... I guess the word is 'field of study' that relates to the best practices and methods for updating a database after deployment? In nHibernate, I establish a SessionFactory and have an initial ru
在编写一个在Fluent Nhibernate / Nhibernate上运行的应用程序时，我有点担心。 我认为任何ORM都是如此（甚至不使用ORM），但是......我猜这个词是'研究领域'，涉及部署后更新数据库的最佳实践和方法。 在nHibernate中，我建立了一个SessionFactory，并有一个初始运行，它根据映射写出数据库。 这很好，我甚至可以手动编写数据库。 但是当我的客户回来并想要添加新内容时呢？ 我可以附加到数据库而不会丢失数据吗
I'm trying to implement a strategy pattern to allow me to allow me to apply some "benefit" to an "account". In the code below, I can't add my implementation of an interface to a dictionary expecting the interface. I think it's some kind of contravariance problem, but it feels like I should be able to do this: EDIT: Since the answer seems to be that it's j
我正试图实施一种战略模式，允许我将某些“收益”应用于“账户”。 在下面的代码中，我无法将接口的实现添加到期望接口的字典中。 我认为这是一种逆转问题，但我觉得我应该能够做到这一点： 编辑： 由于答案似乎是不可能的，对于如何实现我在这里的目标有什么建议？ void Main() { var provider = new BenefitStrategyProvider(); var freeBenefit = new FreeBenefit(); var strategy = provider.GetStrategy(fr
Overview: Here is an summed up description of what I'm doing - I have a C# application that's running constantly that contains a HTTPListener and waits for a request. Then there is a MVC Web Application where on one of the pages is a button that fires some JS that does an ajax post to the address that the HTTP Listener is listening on, when that button is clicked, the listener catches th
概述：下面是我正在做的事情的总结说明 - 我有一个不断运行的C＃应用程序，它包含一个HTTPListener并等待请求。 然后有一个MVC Web应用程序，其中一个页面是一个按钮，它触发一些JS，它会在HTTP侦听器正在侦听的地址上执行ajax张贴，单击该按钮时，侦听器捕获此请求，然后C＃应用程序执行一些其他工作（与问题无关），然后生成一个字节数组。 然后，这个字节数组被送回作为响应原始请求的一部分，所以success的AJAX后发出请
I´m new to mvc and I try to to do a simple Ajax call to my controller, so I can use a date- and timepickers in my create view. I get this error message when I use debugging in IE, but if I do a breakpoint it looks like I got correct data. The parameters dictionary contains a null entry for parameter 'Lokal' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.Act
我是mvc的新手，我尝试对我的控制器进行简单的Ajax调用，以便在创建视图中使用日期和时间选择器。 当我在IE中使用调试时遇到此错误消息，但如果我执行断点，它看起来像我得到正确的数据。 参数字典为方法'System.Web.Mvc.ActionResult CreateEvent（System.String，System.String，System.String，Int32）'的非空类型'System.Int32'的参数'Lokal'包含一个空条目。 'VLVision.Controllers.Samman
I'm new to AWS, I'm trying to lookup an item by UPC within my UWP App. I'm having issues adding the signature to the request URL. I keep receiving "The request signature we calculated does not match the signature you provided." Has any had any experience with making calls to Amazon? There api documentation isn't really aimed towards C# in most places. public as
我是AWS的新手，我试图在UWP应用程序中通过UPC查找项目。 我遇到了将签名添加到请求网址的问题。 我一直收到“我们计算的请求签名与您提供的签名不符。” 有没有任何打电话给亚马逊的经验？ 在大多数地方，api文档并不是针对C＃的。 public async void ItemLookup(string itemID) { Dictionary<string, string> fields = new Dictionary<string, string>(); fields.Add("AssociateTag",
I am having some issues generating a valid signature for Amazon AWS S4 using temporary access keys. I have placed my code below if anybody wouldn't mind spotting out any mistakes I may have made! The response I am getting from their service every time is: "SignatureDoesNotMatch" = "The request signature we calculated does not match the signature you provided. Check your key
我遇到了一些使用临时访问密钥为Amazon AWS S4生成有效签名的问题。 如果有人不介意发现我可能犯的任何错误，我将代码放在下面。 我每次从他们的服务中获得的回复是：“SignatureDoesNotMatch”=“我们计算的请求签名与您提供的签名不匹配。请检查您的密钥和签名方法”。 即使在同一时间戳上使用建议的签名时，我也会得到完全相同的响应。 我现在有点难以忍受，希望能有一个非常简单的独立功能，但是在尝试不同角度的几个小时
Whenever I try to perform a search I receive an unhandled SOAP Exception stating that the request must contain the Parameter Signature. This happens when the following is executed: ItemSearchResponse response = service.ItemSearch(request); AWSECommerceService cs = new AWSECommerceService(); ItemSearchRequest request = new ItemSearchRequest(); request.SearchIndex = "Books"; request.Title = "a
每当我尝试执行搜索时，我都会收到一个未处理的SOAP异常，指出请求必须包含参数签名。 执行以下操作时会发生这种情况： ItemSearchResponse response = service.ItemSearch(request); AWSECommerceService cs = new AWSECommerceService(); ItemSearchRequest request = new ItemSearchRequest(); request.SearchIndex = "Books"; request.Title = "asp.net"; request.ResponseGroup = new string[] { "small"}; ItemSearch
I have been wasting few days on this issue already... The main problem is - I dont know how to POST data. I would like to start by getting OrderReferenceDetails. by looking at MWS Scratchpad (API Section: Off Amazon payments, Operation: GetOferenceDetails). As I understand, first thing I should do, is to calculate signature. So by using this Amazon developer guide, and taking values in examp
我已经在这个问题上浪费了几天...主要问题是 - 我不知道如何POST数据。 我想首先获取OrderReferenceDetails。 通过查看MWS Scratchpad（API部分：关闭亚马逊支付，操作：GetOferenceDetails）。 据我了解，我应该做的第一件事就是计算签名。 所以，通过使用这个Amazon开发人员指南，并使用scratchpad中的示例获取值，我创建了字符串，从中计算签名。 这个字符串看起来像这样 POST mws.amazonservices.com /offamazonpaymen

As of August 15, Amazon made it compulsory to sign all requests made to their Product Advertising API. I thought I had got everything working just fine but when the 15th finally came around, my web application stopped working and pretty much ever since I have been trying to find out how to sign the SOAP requests. Amazon has an outdated sample code for signing requests that doesn't appear t
截至8月15日，亚马逊强制要求对其产品广告API的所有请求进行签名。 我以为我已经能够正常工作了，但是当第15次终于出现时，我的web应用程序停止工作，并且几乎从此我一直在试图找出如何签署SOAP请求。 亚马逊有一个过时的示例代码，用于签署似乎无法在此工作的请求 基本上，我需要知道如何使用最新的C＃SOAP API和.NET 3.5为我的请求添加签名。 我希望我已经提供了足够的细节，如果我没有请随时请我详细说明。 谢谢
