Loss of Precision from C# to SQL Server

This is an issue I am facing which is causing loss of precision when storing in SQL Server database from C# Entity Framework. SQL Server Data Type is decimal(20, 15) In C# Property is defined as public decimal AssignedGrossBudget { get; set; } public decimal AssignedGrossBudget { get; set; } in C# value in variable (AssignedGrossBudget) is 34.09090909090909 But in SQL Server table it is 3

从C#到SQL Server的精度损失

这是我遇到的问题,当从C#Entity Framework存储在SQL Server数据库中时,会导致精度损失。 SQL Server数据类型是decimal(20, 15) 在C#中,Property被定义为public decimal AssignedGrossBudget { get; set; } public decimal AssignedGrossBudget { get; set; } 在变量(AssignedGrossBudget)中的C#值是34.09090909090909 但在SQL Server表中它是34.090000000000000 什么可能是错的? (我正在使用实体框架db.Sav

A string tokenizer in C++ that allows multiple separators

Possible Duplicate: C++: How to split a string? Is there a way to tokenize a string in C++ with multiple separators? In C# I would have done: string[] tokens = "adsl, dkks; dk".Split(new [] { ",", " ", ";" }, StringSplitOptions.RemoveEmpty); Use boost::tokenizer. It supports multiple separators. In fact, you don't really even need boost::tokenizer. If all you want is a split, use b

C ++中的字符串标记器,允许使用多个分隔符

可能重复: C ++:如何分割一个字符串? 有没有办法使用多个分隔符来标记C ++中的字符串? 在C#中我会完成: string[] tokens = "adsl, dkks; dk".Split(new [] { ",", " ", ";" }, StringSplitOptions.RemoveEmpty); 使用boost :: tokenizer。 它支持多个分隔符。 事实上,你甚至不需要boost :: tokenizer。 如果你想要的只是一个分割,使用boost :: split。 该文档有一个示例:http://www.boost.org/doc/libs/1_4

C# Split A String By Another String

I've been using the Split() method to split strings, but this only appears to work if you are splitting a string by a character. Is there any way to split a string , with another string being the split by parameter? I've tried converting the splitter into a character array, with no luck. In other words, I'd like to split the string : THExxQUICKxxBROWNxxFOX by xx , and return a

C#将字符串拆分为另一个字符串

我一直在使用Split()方法来拆分字符串,但是这只有在你用字符拆分字符串时才会起作用。 有没有什么办法来分割一个string ,另一个字符串是按参数拆分? 我已经尝试将分离器转换为字符数组,但没有运气。 换句话说,我想分割string : THExxQUICKxxBROWNxxFOX 由xx ,并返回一个数组值: THE,QUICK,BROWN,FOX 为了分割一个字符串,你必须使用字符串数组重载。 string data = "THExxQUICKxxBROWNxxFOX"; return data

Should aggregate roots have dependencies?

In Eric Evan's book "Domain Driven Design" (which people often call 'the best example for DDD'), there are many examples of aggregate roots (mostly domain models or even entities) that fullfil a certain request. Let's take the following example: public Car : IAggregateRoot { public List<Wheel> Wheels { get; set; } public void ReplaceWheels(); } In or

聚合根需要依赖吗?

在埃里克埃文的“域驱动设计”一书中(人们经常称这是“DDD最好的例子”),有很多聚合根源(主要是域模型甚至实体)的例子满足了某些请求。 我们来看下面的例子: public Car : IAggregateRoot { public List<Wheel> Wheels { get; set; } public void ReplaceWheels(); } 为了更换车轮,我必须从GarageService请求一组新的车轮,它本身从WheelRepository收集车轮。 在一种情况下,我不是一个客户,而是一个

How to make sure we have only one instance, and it is disposed in a correct way

In the software I am writing I will read some data from an external device (connected via USB). The drivers I have been given (dll file) are not thread safe and only one instance can be used at a time. I have to write a wrapper to these drivers in C#. Given that I have a multi-threaded application, I would like to make sure that: Always only one instance is used (probably the wrapper being a

如何确保我们只有一个实例,并以正确的方式进行处理

在我写的软件中,我将从外部设备(通过USB连接)读取一些数据。 我得到的驱动程序(dll文件)不是线程安全的,一次只能使用一个实例。 我必须在C#中为这些驱动程序编写一个封装器。 鉴于我有一个多线程应用程序,我想确保: 总是只使用一个实例(可能是一个单例包装?)。 它可以被处置以释放那里的驱动程序和资源( IDisposable ?)。 从一次性辛格尔顿我可以看到,意见分歧,可以在单是IDisposable或没有。 也许有

Convert C to MIPS64 Assembly

I have written some code in C and need to convert this to MIPS 64, with and without optimisation. I have been trying to convert this with gcc but this converts it to x86 which is far more complex. Furthermore, I have been trying to find a cross compiler but have not been able to get any compiler to work. Any help and suggestions will tremendously be appreciated. Kind regards, After downloa

将C转换为MIPS64汇编

我用C语言编写了一些代码,需要将其转换为MIPS 64,无论是否进行优化。 我一直在试图用gcc来转换它,但是这会将它转换为更加复杂的x86。 此外,我一直在试图找到一个交叉编译器,但一直未能获得任何编译器的工作。 任何帮助和建议将非常感激。 亲切的问候, 在下载并安装MIPS的Codesourcery代码平台之后,调用MIPS 64修订版2架构的MIPS gcc交叉编译器,如下所示: C:Program Files (x86)CodeSourcerySourcery_CodeBench_L

Fastest way of getting properties of ManagementObject

I have a method that returns list of services on remote machine. I'm getting the ManagementObjectCollection using ManagementObjectSearcher.Get() and WIN32 query. Then in foreach loop I'm creating instance of my Service class and add it to result List. While initializing new Service I'm getting ManagementObject properties using GetPropertyValue(string). The problem i'm facing i

获取ManagementObject属性的最快方法

我有一个方法返回远程机器上的服务列表。 我得到ManagementObjectCollection使用ManagementObjectSearcher.Get()和WIN32查询。 然后在foreach循环中创建我的Service类的实例并将其添加到结果List中。 在初始化新服务时,我使用GetPropertyValue(字符串)获取ManagementObject属性。 我面临的问题是这个过程非常缓慢。 我认为GetPropertyValue很慢(我每次循环使用它7次)。 有更快的方法从ManagementObject类获取属性吗
