Override a virtual method in a partial class

问题 I am currently working with the nopCommerce source code and trying my best to avoid editing the source at all, but instead using partial classes and plugins that are separate from the source code, should we ever need to upgrade versions. I want to make some changes to the code that places an order, by using a partial class in the same assembly: Orignal Source Code: namespace Nop.Services.Orders { public partial class OrderProcessingService : IOrderProcessingService { public virtual

What are the benefits to using a partial class as opposed to an abstract one?

I have been reading Programming Microsoft® Visual C#® 2008: The Language to get a better understanding of C# and what can be done with it. I came across partial classes which I had already encountered from ASP.Net's Page class. To me it seems that you can do what partial classes do with an abstract class and an overridden one. Obviously one team will be in control of the interface via the abstract methods but you would be relying on each other anyway. And if the goal is collaboration then isn't that what source control and other tools solve. I am just missing the point to a partial class. Also

Access class fields from partial class

问题 I'm currently in a scenario in which I have to make use of partial classes. In this partial class I have a few methods that need to address fields in the other class. for example Edit: I'm sorry: the first class is already declared partial ! public partial class myClass { private string _myString; public string myString { get { return _myString; } set { _myString = value; } } } and public partial class myClass { public void doSomething() { myString = "newString"; } } The compiler says

Is it possible to declare a partial class in two projects

半腔热情 提交于 2019-12-01 15:09:39
问题 Consider we create a partial class in Project1 and we have a Project2 that has reference to Project1 .How is it possible to declare some other method of partial class in Project2 ? thanks 回答1: The partial construct is only a compiler functionality, to allow a class to be spread out in several source files. The compiled class still lives in one and only one class library (dll file). There are two ways to extend a class in another library: Inheritance, unless the class is sealed . This requires

C# Partial Classes

I currently have a solution with multiple projects that mostly use the same classes. As a result, it appeared to me that it would be a good idea to add a class library containing these classes in the solution instead of repeating the class in each project. However, one project I have requires a few additional properties to some of the classes that are specific to that project and will not be used anywhere else. As a result, I thought that I should use partial classes to add these properties. So I have done something like this: In the class library: namespace MyClassLibrary { public partial

WinForm partial classes

大憨熊 提交于 2019-11-30 08:34:52
I have a WinForm project that contains a form called MainUI. You can see that the automatically generated partial class shows up as a node under MainUI.cs . Is there a way to "move" my self created partial class MainUI.Other.cs under MainUI.cs so that it'll show as another node? Close the solution in Visual Studio, and open your .csproj file in a text editor. Find MainUI.Other.cs, and add the following XML element: <Compile Include="MainUI.Other.cs"> <SubType>Form</SubType> <DependentUpon>MainUI.cs</DependentUpon> <!-- this is the magic incantation --> </Compile> Reopen the solution in Visual

How to add data annotations to partial class?

I have an auto generated class with a property on it. I want to add some data annotations to that property in another partial class of the same type. How would I do that? namespace MyApp.BusinessObjects { [DataContract(IsReference = true)] public partial class SomeClass: IObjectWithChangeTracker, INotifyPropertyChanged { [DataMember] public string Name { get { return _name; } set { if (_name != value) { _name = value; OnPropertyChanged("Name"); } } } private string _name; } } and in another file I have: namespace MyApp.BusinessObjects { public partial class SomeClass { private SomeClass() { }

C++ partial method specialization

白昼怎懂夜的黑 提交于 2019-11-29 13:19:49
Is there a partial specialization for template class method? template <class A, class B> class C { void foo(); } it doesn't work to specialize it like this: template <class A> void C<A, CObject>::foo() {}; Any help? If you are already have specialized class you could give different implementation of foo in specialized class: template<typename A, typename B> class C { public: void foo() { cout << "default" << endl; }; }; template<typename A> class C<A, CObject> { public: void foo() { cout << "CObject" << endl; }; }; To specialize member function in Visual C++ 2008 you could make it template too

EF 4, how to add partial classes

亡梦爱人 提交于 2019-11-29 07:20:26
I needed to extend my EF partial classes, because I want to add some functionality to able to use Oracle's sequences , however I really don't know how to use this partial class thing, I made a seperate .cs file and name it as one of my auto-generated classes as follows: namespace GlassStoreDAL { public partial class CAR { private int _sequences; public int sequences { get { return _sequences; } set { _sequences = value; } } } } Now I assumed that, on my BLL - which references GlassStoreDAL - I can find my "sequences" property , but apparently something goes wrong, I would appreciate any help

A way to implement partial classes in java

限于喜欢 提交于 2019-11-29 01:04:42
I have an interface that I want to implement in separate classes after doing a quick google search apparently, Java doesn't have partial classes. Is there a way that I can do this or am I stuck throwing all of my code into one class? Basically, I am trying to write a service. Some of the service methods really belong in their own class and seem kind of illogical in the same class. Here is an example of what I am trying to do. package com.upmc.esdm.messaging.epcd.service; import java.util.List; import javax.ejb.Remote; import com.upmc.esdm.messaging.epcd13jpa.entities.EmailDomainTrust; @Remote
