My question is as easy as it seems: I want to find out which version of C# I am using. If I would be using python I would do something like python -V from command line, or type import sys print sys.version In php I would do something like this: phpinfo(); in java: java -version But I was not able to find how to achieve this in C#. I am completely new to C#, so please do not beat me too ha
我的问题和看起来一样简单:我想知道我正在使用哪个版本的C#。 如果我将使用python,我会从命令行或类型中执行类似python -V import sys print sys.version 在PHP中,我会做这样的事情: phpinfo(); 在java: java -version 但是我无法找到如何在C#中实现这一点。 我对C#完全陌生,所以请不要太狠狠地打我。 让我惊讶的是,我无法在SO上找到这个答案,因此我认为我在找东西时错过了某些东西或错误。 顺便说一句,这
I am creating a dictionary in a C# file with the following code: private readonly Dictionary<string, XlFileFormat> FILE_TYPE_DICT = new Dictionary<string, XlFileFormat> { {"csv", XlFileFormat.xlCSV}, {"html", XlFileFormat.xlHtml} }; There is a red line under new with the error: Feature 'collection initilializer' cannot be use
我使用以下代码在C#文件中创建字典: private readonly Dictionary<string, XlFileFormat> FILE_TYPE_DICT = new Dictionary<string, XlFileFormat> { {"csv", XlFileFormat.xlCSV}, {"html", XlFileFormat.xlHtml} }; new错误下面有一条红线: 功能'collection initilializer'不能使用,因为它不是ISO-2 C#语言规范的一部分 任何人都可以解释这里
Possible Duplicates: What are the correct version numbers for C#? List of new features in C# 2.0, 3.0 and 4.0 What is the difference between C# versions like ver 2.0 and ver 3.0? Please help me explain in detail. What are the exact differences? Many new features support the introduction of LINQ (they can be used in many different contexts, but they are very useful in the context of LIN
可能重复: 什么是C#的正确版本号? C#2.0,3.0和4.0中的新功能列表 C#版本如ver 2.0和ver 3.0有什么区别? 请帮我详细解释一下。 有什么确切的区别? 许多新功能都支持LINQ的引入(它们可以用在许多不同的环境中,但它们在LINQ环境中非常有用)。 我强烈建议你阅读Jon Skeet的C#深入了解每个新功能的详细解释。 从Jon Skeet的书C#深入,网页在这里是详细的。 C#2,介绍泛型,可空类型,匿名方法,迭代器
This question already has an answer here: What are the correct version numbers for C#? 9 answers I am not sure what your actual question is, but if it is what are the current versions.. C#: 3.0 .NET Framework: 3.5 You might also want to take a look at this breakdown chart. It provides the Framework, language and CLR relations. C# 1.0 - Managed Code C# 2.0 - Generics, Nullable Type
这个问题在这里已经有了答案: 什么是C#的正确版本号? 9个答案 我不确定你的实际问题是什么,但是如果它是目前的版本.. C#:3.0 .NET Framework:3.5 你可能也想看看这个细分表。 它提供了框架,语言和CLR关系。 C#1.0 - 托管代码 C#2.0 - 泛型,可空类型,匿名委托,部分类/方法 C#3.0 - LINQ,Lambda表达式,隐式变量分类,简化对象初始化 //相关? 或许也许 .net 2 C#2 .net 3 C#2 .n
I have an ASP.NET Core project. It is .NET Framework based. I have been working with .NET Version 4.6, but am happy to upgrade to 4.6.2 or 4.7. I have both installed on my machine. The referenced NuGet packages are numerous and version numbers varied. But, it seems that roughly speaking, I am using version 1.1.3 of ASP.NET Core. I want to upgrade to the latest version of ASP.NET Core and A
我有一个ASP.NET Core项目。 它是基于.NET Framework的。 我一直在使用.NET 4.6,但很高兴升级到4.6.2或4.7。 我都安装在我的机器上。 引用的NuGet软件包数量众多,版本号各不相同。 但是,似乎大致来说,我正在使用ASP.NET Core 1.1.3版本。 我想升级到最新版本的ASP.NET Core和ASP.NET Core MVC,但每次尝试时,都会收到此错误消息: 无法安装软件包'Microsoft.AspNetCore.Mvc.Core 2.0.0'。 您正在尝试将此
I'm currently implementing an elementary solution to load the Services in an Asp.Net Core by reflection instead of having to pass every single type. To have some wiggle-room, I created a static helper returning me the assembly-types using the new core-reflection types: internal static class ReflectionTypeHelper { private static readonly Assembly _currentAssembly = typeof(ServiceContaine
我目前正在实现一个基本的解决方案,通过反射将服务加载到Asp.Net Core中,而不必传递每一种类型。 为了有一些摆动空间,我创建了一个静态帮助器,使用新的core-reflection类型返回装配类型: internal static class ReflectionTypeHelper { private static readonly Assembly _currentAssembly = typeof(ServiceContainerInitializer).GetTypeInfo().Assembly; internal static IReadOnlyCollection<Type> Scan
I have been working all day by now to get my app deployed to Azure, but can't get it to work, while it previously worked like a charm. At this point I even deleted the entire Webapp, database and database server. I have updated some packages, but at this point there are no errors. Tools I have put all the tools here that are installed. Maybe there might be a conflict that I am not aw
我现在一整天都在将我的应用程序部署到Azure,但无法使其工作,而以前它像魅力一样工作。 此时我甚至删除了整个Webapp,数据库和数据库服务器。 我更新了一些软件包,但在这一点上没有错误。 工具 我已经安装了所有的工具。 也许可能会有我不知道的冲突。 ASP.NET Core> = 1.0.1,EF Core> = 1.0.1 带有更新的Visual Studio 2015 Enterprise(包括ReSharper)。 Entity Framework 6.1.3 Visual Studio 2015
I'm using Visual Studio 2015 Update 3, and I have an Asp.Net Core project targeting the full .Net Framework (4.6.1). I want to add a reference to an F# library in the same solution, but VS complains that it can't reference projects of that type, (it works fine for C# libraries): "The following projects are not supported as references : - Project (project name) type is unsupported
我正在使用Visual Studio 2015 Update 3,并且我有一个针对完整.Net Framework(4.6.1)的Asp.Net Core项目。 我想在同一个解决方案中添加对F#库的引用,但是VS抱怨说它不能引用该类型的项目(对于C#库而言,它工作正常): “以下项目不支持作为参考: - 当前项目不支持项目(项目名称)类型,并且不能被引用。” 我相信F#4.1版本仍然是预发行版,但正如我所说的,这是针对完整框架的,看起来这应该起作用。
To learn more about the new exciting Asp.Net-5 framework, I'm trying to build a web application using the newly released Visual Studio 2015 CTP-6. Most things looks really promising, but I can't seem to find Request.IsAjaxRequest() - a functionality I've been using quite frequently on older MVC projects. Is there a better way to do this - that made them remove this method - or is
要了解更多关于新的令人兴奋的Asp.Net-5框架,我正在尝试使用新发布的Visual Studio 2015 CTP-6构建一个Web应用程序。 大多数东西看起来非常有前途,但我似乎无法找到Request.IsAjaxRequest() - 这是我在较老的MVC项目中经常使用的功能。 有没有更好的方法来做到这一点 - 这使得他们删除了这种方法 - 或者它在其他地方“隐藏”了吗? 感谢您在哪里找到它或做什么的建议! 我有点困惑,因为标题提到了MVC 5。 在MVC6 gi
I am wondering what the different is between IQueryable, List, IEnumerator and when I should using each one? For instance when using linq to sql I would do something like this public List<User> GetUsers() { return db.User.where(/* some query here */).ToList(); } now I am wondering if I should be using IQueryable instead but I am unsure of the advantages of using it over the list. I
我想知道IQueryable,List,IEnumerator和我应该使用每一个的区别是什么? 例如,当使用LINQ到SQL我会做这样的事情 public List<User> GetUsers() { return db.User.where(/* some query here */).ToList(); } 现在我想知道是否应该使用IQueryable,但我不确定在列表中使用它的优点。 IQueryable<T>旨在允许查询提供者(例如,LINQ to SQL或实体框架之类的ORM)使用查询中包含的表达式将请求转换为另一种格
