I am defining a model in EF4 CTP5 where I need to map an inherited entity only when the value of an id is greater than 0. the code looks like this. public class Parent { public int ID { get; set; } public string FirstName { get; set; } public string LastName { get; set; } } public class Child : Parent { public int SchoolID { get; set; } } In the OnModelCreating method... modelBuil
我正在EF4 CTP5中定义一个模型,只有当id的值大于0时,我需要映射继承的实体。代码如下所示。 public class Parent { public int ID { get; set; } public string FirstName { get; set; } public string LastName { get; set; } } public class Child : Parent { public int SchoolID { get; set; } } 在OnModelCreating方法中... modelBuilder.Entity<Parent>().Map<Child>( reg =>
I need to get the Display Name of the current user, and cannot find a solution that always works. Just for clarity, I'm not looking for the username. I need the "John Doe". The value displayed on the Start Menu. There are many posts about this question however none have solved my problem. Get Windows User Display Name How do I get the AD Display Name of the currently logged
我需要获取当前用户的显示名称,并且找不到始终有效的解决方案。 为了清楚起见,我不在寻找用户名。 我需要“John Doe”。 开始菜单上显示的值。 有很多关于这个问题的帖子,但没有解决我的问题。 获取Windows用户显示名称 如何获取当前登录用户的AD显示名称 这两个帖子引导我: PrincipalContext context = domain.Equals(Environment.MachineName, StringComparison.CurrentCultureIgnoreCase) ? new PrincipalCo
For example, see How to get the current ProcessID? No one bothered to call Dispose for an object returned by System.Diagnostics.Process.GetCurrentProcess() . Should it actually be called? Please explain why. Yes, and actually it is important too. If you see the actual source, you will see the Dispose isn't just inherited from Component , it does something too. It seems to me, looki
例如,请参阅 如何获取当前的ProcessID? 没有人打扰为System.Diagnostics.Process.GetCurrentProcess()返回的对象调用Dispose。 它应该被称为? 请解释原因。 是的,其实也很重要。 如果你看到实际的源代码,你会看到Dispose不仅仅是从Component继承的,它也做了一些事情。 在我看来,查看该代码时,在EnableRaisingEvents设置为true时最重要,因为这涉及创建等待句柄。 该句柄需要释放以防止内存泄漏。
When using the .NET Compiler Platform SDK Templates (https://visualstudiogallery.msdn.microsoft.com/849f3ab1-05cf-4682-b4af-ef995e2aa1a5) to create a Roslyn Diagnostic with Code Fix, I get both a NuGet package and a VSIX - as stated by the readme: "Building this project will produce an analyzer .dll, as well as the following two ways you may wish to package that analyzer: A NuGet packa
使用.NET Compiler Platform SDK模板时(https://visualstudiogallery.msdn.microsoft.com/849f3ab1-05cf-4682-b4af-ef995e2aa1a5) 使用Code Fix创建Roslyn Diagnostic,我得到了一个NuGet包和一个VSIX - 正如自述文件所述: “构建此项目将生成一个分析器.dll,以及以下两种您可能想要打包该分析器的方法: 一个NuGet包(.nupkg文件),将您的程序集添加为参与构建的项目本地分析器。 VSIX扩展名(.vsix文件),将您
I am working on an ASP.NET MVC 4 web application that generates large and complicated reports. I want to write Unit Tests that render a View in order to make sure the View doesn't blow up depending on the Model: [Test] public void ExampleTest(){ var reportModel = new ReportModel(); var reportHtml = RenderRazorView( @"....Report.MvcViewsReportIndex.c

I'm reading some C code embedded with a few assembly code. I understand that __asm__ is a statement to run assembly code, but what does __asm__ do in the following code? According to the output (ie, r = 16 ), it seems that __asm__ does not effect the variable r . Isn't it? #include <stdio.h> static void foo() { static volatile unsigned int r __asm__ ("0x0019"); r |= 1 &l
我正在阅读一些嵌入了几个汇编代码的C代码。 我知道__asm__是运行汇编代码的语句,但是__asm__在下面的代码中做了什么? 根据输出(即r = 16 ),似乎__asm__不会影响变量r 。 不是吗? #include <stdio.h> static void foo() { static volatile unsigned int r __asm__ ("0x0019"); r |= 1 << 4; printf("foo: %un", r); } 平台:OSX Yosemite上的Apple LLVM 6.0版(clang-600.0.56)(基于LLVM
In the code below ViewState["L"] stores a List<string> . I create a new instance of List and assign the casted value of a viewstate to it. List<string> myList = new List<string>(); myList=(List<string>)ViewState["L"]; Response.Write(myList.Equals(ViewState["L"]));// returns True As you can see, .Equals() method tells me that the Viewstate object and the List
在下面的代码中, ViewState["L"]存储List<string> 。 我创建一个List的新实例,并为其分配一个视图状态的值。 List<string> myList = new List<string>(); myList=(List<string>)ViewState["L"]; Response.Write(myList.Equals(ViewState["L"]));// returns True 正如你所看到的, .Equals()方法告诉我Viewstate对象和List对象是一样的。 现在我向你们提出的问题是, List和Viewstate
