EF Eager fetching derived class

I´m using EF6 and trying to eager fetch the whole structure of an object. The problem is that i´m using inheritance. Let´s say that i have this classes. DbContext DbSet<A> A { get; set; } Example classes public class A { public string Id { get; set; } public IList<Base> Bases { get; set; } } public abstract class Base { public int Id { get; set; } public strin

EF预先获取派生类

我正在使用EF6并试图抓取对象的整个结构。 问题是我使用继承。 我们说我有这个课程。 的DbContext DbSet<A> A { get; set; } 示例类 public class A { public string Id { get; set; } public IList<Base> Bases { get; set; } } public abstract class Base { public int Id { get; set; } public string Name { get; set; } } public abstract class Base1 : Base { public SomeClas

Web User Controls in different Project

I put some self made Web User Controls in a seperate Project "WebControls" and now want to reuse them from another Project My Control consists of: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TestControl.ascx.cs" Inherits="WebControls.TestControl" %> <asp:Label ID="lblTest" runat="server" ></asp:Label> <asp:TextBox ID="textBox" runat="serv

不同项目中的Web用户控制

我在一个单独的项目“WebControls”中放了一些自制的Web用户控件,现在想从其他项目中重用它们 我的控制包括: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TestControl.ascx.cs" Inherits="WebControls.TestControl" %> <asp:Label ID="lblTest" runat="server" ></asp:Label> <asp:TextBox ID="textBox" runat="server" Width="" /> <asp:HiddenField ID="hiddenFi

What is the strict aliasing rule?

When asking about common undefined behavior in C, souls more enlightened than I referred to the strict aliasing rule. What are they talking about? A typical situation you encounter strict aliasing problems is when overlaying a struct (like a device/network msg) onto a buffer of the word size of your system (like a pointer to uint32_t s or uint16_t s). When you overlay a struct onto such a bu

什么是严格的别名规则?

在询问C语言中常见的未定义行为时,灵魂比我提到严格的别名规则更加开明。 他们在说什么? 遇到严格别名问题的典型情况是将结构(如设备/网络信息)覆盖到系统字长度的缓冲区上(如指向uint32_t s或uint16_t s的指针)。 当通过指针转换将结构覆盖到这样的缓冲区或缓冲区上时,您可以轻松违反严格的别名规则。 所以在这种设置中,如果我想发送消息给某个东西,我必须有两个不兼容的指针指向同一块内存。 然后我可能天真

Realistic usage of the C99 'restrict' keyword?

I was browsing through some documentation and questions/answers and saw it mentioned. I read a brief description, stating that it would be basically a promise from the programmer that the pointer won't be used to point somewhere else. Can anyone offer some realistic cases where its worth actually using this? restrict says that the pointer is the only thing that accesses the underlying ob

C99'restrict'关键字的实际使用情况?

我浏览了一些文档和问题/答案,并看到它提到。 我读了一个简短的描述,指出这基本上是程序员的一个承诺,即指针不会被用来指向别的地方。 任何人都可以提供一些实际情况,其实际价值在于使用它吗 restrict指出指针是访问底层对象的唯一东西。 它消除了指针混叠的可能性,使编译器能够更好地进行优化。 例如,假设我有一台机器,它具有可以在内存中乘以数字向量的专用指令,并且具有以下代码: void MultiplyArrays(int*

Access files on remote server

I am creating a website and I need to display an image of the employee next to their details. The details about the employee are stored in a SQL Server database and one of the fields contains the name of the image eg Picturesemployeename.jpg .

访问远程服务器上的文件

我正在创建一个网站,我需要在他们的详细信息旁边显示员工的图像。 有关员工的详细信息存储在SQL Server数据库中,其中一个字段包含图像的名称,例如 Pictures employeename.jpg 。 该文件的实际位置在服务器上,并且是该URL的URL \服务器 Folder1中文件夹2 图片图片 在我的代码中,我将两个部分连接起来构成以下字符串 \服务器 Folder1中文件夹2 图片图片图片 employeename.jpg 然后我将它附加到image.imageurl,

Store the name but not the path of all folders in a specified folder to a list?

So I have a folder in the same directory as my .exe console application. I want to make a list of all the folders inside of that folder (it's called ClientFiles ) but I don't want the full paths. So if I have a hierarchy like this: ClientFiles --- Folder1 --- Folder2 --- Folder3 I should end up with a list containing the strings: "Folder1", "Folder2", "Fold

将名称而不是指定文件夹中所有文件夹的路径存储到列表中?

所以我有一个与我的.exe控制台应用程序在同一个目录中的文件夹。 我想列出该文件夹内的所有文件夹(称为ClientFiles )的列表,但我不想要完整的路径。 所以如果我有这样的层次结构: ClientFiles --- Folder1 --- Folder2 --- Folder3 我最终会得到一个包含字符串的列表:“文件夹1”,“文件夹2”,“文件夹3”。 这就是我现在所拥有的: List<string> clientNumbers = Directory .GetDirectories(AppDomain.Curren

Why is access denied when I try to move a directory?

为什么当我尝试移动目录时访问被拒绝?

我有两个目录:folder1和folder2。 folder1包含一个文件。 我想要将folder1移到folder2下面以生成folder2 folder1。 当我尝试使用下面的C#代码执行此操作时,我得到: System.IO.IOException:访问路径'E: www dev test MoveDirectories folder1'被拒绝。 相关代码: // In Page_Load. MoveDirectory("folder1"); // Method for moving directories. protected void MoveDirectory(string strMoveThis) {

How to use LogonUser properly to impersonate domain user from workgroup client

ASP.NET: Impersonate against a domain on VMWare This question is what I am asking, but the answer does not provide details on how the _token is derived. It seems to only use WindowsIdentity.GetCurrent().Token so there's no impersonation happening. Can I impersonate a user on a different Active Directory domain in .NET? This next question has conflicting answers, with the accepted one b

如何正确使用LogonUser从工作组客户端模拟域用户

ASP.NET:针对VMWare上的域进行模拟 这个问题是我问的,但答案并没有提供关于_token如何派生的细节。 它似乎只使用WindowsIdentity.GetCurrent().Token所以没有模仿发生。 我可以在.NET中模拟不同的Active Directory域上的用户吗? 接下来的问题有相互矛盾的答案,接受的答案有一个评论:“我开始怀疑我的问题在别处。” 没有帮助。 LogonUser只适用于我的域名 接下来的问题似乎暗示这是不可能的,但它涉及2个域名,所
