I've written a fairly basic AuthenticationHandler<T> derived class for performing custom authentication for my REST services. I had assumed (yes, I know, bad idea) that ApplyResponseChallengeAsync would only be called if I actually need to apply my challenge - eg it's described as: Override this method to dela(sic) with 401 challenge concerns, if an authentication scheme in ques
我已经编写了一个相当基本的AuthenticationHandler<T>派生类来为我的REST服务执行自定义验证。 我曾假设(是的,我知道,坏主意) ApplyResponseChallengeAsync只会在我需要应用我的挑战时被调用 - 例如它被描述为: 如果所考虑的认证方案将认证交互作为其请求流的一部分进行处理,则将此方法重写为dela(原文如此)与401挑战问题。 (如添加响应标题或将401结果更改为登录页面或外部登录位置的302)。 这听起来只
I am having a problem validating a ComboBox using IDataErrorInfo . I set up 1 textbox and 1 combobox, upon running the program the first focus is on textbox, when I hit tab to focus in the combobox I am getting: InvalidOperationException: 'validationTooltip' name cannot be found in the name scope of 'System.Windows.Controls.ToolTip'.` To help you helping me here's some p
我有一个使用IDataErrorInfo验证ComboBox的问题。 我设置了1个文本框和1个组合框,在运行该程序时,第一个焦点位于文本框中,当我点击标签以关注组合框时,我得到: InvalidOperationException:在'System.Windows.Controls.ToolTip'的名称范围中找不到'validationTooltip'名称。 为了帮助我,这里是我的XAML的一部分: <Window.DataContext> <ViewModels:MainWindowViewModel/> </Win
Related to this question, Is await supposed to restore the context (specifically the context represented by Thread.CurrentContext ) for a ContextBoundObject ? Consider the below: class Program { static void Main(string[] args) { var c1 = new Class1(); Console.WriteLine("Method1"); var t = c1.Method1(); t.Wait(); Console.WriteLine("Method2");
与这个问题有关, 正在await应该恢复的背景下(特别是通过代表的情境Thread.CurrentContext )为ContextBoundObject ? 考虑下面的内容: class Program { static void Main(string[] args) { var c1 = new Class1(); Console.WriteLine("Method1"); var t = c1.Method1(); t.Wait(); Console.WriteLine("Method2"); var t2 = c1.Method2(); t2.Wait();
I just bumped into a really strange C# behavior, and I'd be glad if someone could explain it to me. Say, I have the following class: class Program { static int len = 1; static void Main(string[] args) { Func<double, double> call = len => 1; len = 1; // error: 'len' conflicts with the declaration 'csutils.Program.len' Program.len = 1; // ok }
我碰到了一个非常奇怪的C#行为,如果有人能够向我解释,我会很高兴。 说,我有以下班级: class Program { static int len = 1; static void Main(string[] args) { Func<double, double> call = len => 1; len = 1; // error: 'len' conflicts with the declaration 'csutils.Program.len' Program.len = 1; // ok } } 就我所知,在评论中,我在视野中有以下对象: len
Why is this code correct: @{ Html.RenderAction("PostImagesForPost", "BlogPost", new { id = Model.ID }); } And this code @Html.RenderAction("PostImagesForPost", "BlogPost", new { id = Model.ID }) through this error message: Compiler Error Message: CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has
为什么这段代码是正确的: @{ Html.RenderAction("PostImagesForPost", "BlogPost", new { id = Model.ID }); } 和这个代码 @Html.RenderAction("PostImagesForPost", "BlogPost", new { id = Model.ID }) 通过这个错误信息: 编译器错误消息:CS1502:'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)'的最佳重载方法匹配有一些无效参数 为什么使用'{'
例如,在多线程时,我需要锁定一个bool值吗? There is no such thing as an atomic type. Only operations can be atomic. Reading and writing a data type that fits into a single word ( int on a 32-bit processor, long on a 64-bit processor) is technically "atomic", but the jitter and/or processor can decide to reorder instructions and thus create unexpected race conditions, so you either ne
例如,在多线程时,我需要锁定一个bool值吗? 没有像原子类型那样的东西。 只有操作可以是原子的。 读取和写入装配到一个字(数据类型int上的32位处理器, long在64位处理器)在技术上是“原子”,但抖动和/或处理器可以决定指令重新排序,从而创造意外的竞态条件,所以你要么需要使用lock序列化访问,使用Interlocked类进行写操作(以及在某些情况下读取),要么声明变量volatile 。 简短的回答是:如果两个不同的线程可以访

我试图让我的模块显示一个printk 。 我是新来的,所以我可能会有一些编程错误。 这是我的模块C文件: #include <linux/linkage.h> #include <linux/time.h> #include <linux/module.h> asmlinkage long sys_mycall(int myid, char* firstname) { printk ("Hello, %s! n sys_mycall called from process %d with ID %d. n", firstname, current->id, myid); return 0; } static int m
I have a basic Azure table storage query working using the Windows Azure Storage Client 3.0. What's the easiest way to convert this to an async query? Is it possible to use the async await pattern? //Setup the storage account connection var cloudStorageAccount = CloudStorageAccount.Parse(connectionString); var cloudTableClient = cloudStorageAccount.CreateCloudTableClient(); var table = clo
我有一个基本的Azure表存储查询使用Windows Azure存储客户端3.0工作。 将此转换为异步查询的最简单方法是什么? 是否可以使用异步等待模式? //Setup the storage account connection var cloudStorageAccount = CloudStorageAccount.Parse(connectionString); var cloudTableClient = cloudStorageAccount.CreateCloudTableClient(); var table = cloudTableClient.GetTableReference("SampleTable"); //Get the context var
I have an ASP.NET 3.5 app using WebForms, currently it is being hosted on IIS6. Everything behaves great. However, after switching to a Windows 2012 server with IIS8 installed, we intermittently get truncated requests. The majority of the time this manifests in a viewstate exception in our event log, however, on forms that do not have ViewState, we get incomplete posts (the last few fields ar
我有一个使用WebForms的ASP.NET 3.5应用程序,目前它被托管在IIS6上。 一切都很好。 但是,切换到安装了IIS8的Windows 2012服务器后,我们会间歇性地收到截断的请求。 大多数情况下,这会在我们的事件日志中显示一个视图状态异常,但是,在没有ViewState的表单上,我们会收到不完整的帖子(最后几个字段丢失/部分截断)。 这变得很麻烦,我们升级到微软的支持,经过数周的调试,他们说这是II7及以上的“正确”行为。 他们的
First of all, I am using EF 6.0 with Code First approach. My context Configuration is set to Enable "Proxy Creation" and "Lazy Loading". My question is: Does the lazy loading work with results of a method that returns IEnumerable (and not IQueryable )? I think the code below is more explanatory: public void Test() { var company = GetCompanies().FirstOrDefault();
首先,我使用Code First方法使用EF 6.0。 我的context配置设置为启用“代理创建”和“延迟加载”。 我的问题是:延迟加载是否与返回IEnumerable (而不是IQueryable )的方法的结果一起工作? 我认为下面的代码更具说明性: public void Test() { var company = GetCompanies().FirstOrDefault(); if (company.Employees.Count() > 0) { //I got here without errors! } } public IEnumerable<
