How are partial methods used in C# 3.0?

阅读更多关于 How are partial methods used in C# 3.0?

问题 I have read about partial methods in the latest C# language specification, so I understand the principles, but I'm wondering how people are actually using them. Is there a particular design pattern that benefits from partial methods? 回答1: Partial methods have been introduced for similar reasons to why partial classes were in .Net 2. A partial class is one that can be split across multiple files - the compiler builds them all into one file as it runs. The advantage for this is that Visual

How to use partial method in C# to extend existing implemetation

阅读更多关于 How to use partial method in C# to extend existing implemetation

问题 It would be great if this would work. Am I trying to implement my idea in the wrong way? I would like to use partial method, to be able to extend existing code, and simply plug in/out implementation of methods. Basically exactly what the reference is stating: Partial methods enable class designers to provide method hooks, similar to event handlers, that developers may decide to implement or not. If the developer does not supply an implementation, the compiler removes the signature at compile

C# Why can partial methods use ref, but not out?

阅读更多关于 C# Why can partial methods use ref, but not out?

问题 Pretty straight forward. MSDN states that you can use ref, but not out for partial methods. I'm just curious as to the why ? It was my understanding that when code is compiled, the partials are merged, so what is up with the restriction? Is there more to partial than just making code files cleaner and organized (i.e. eyecandy)? Reference: MSDN Article - "Partial methods can have ref but not out parameters." 回答1: You got to consider what happens if the partial method isn't implemented. What

问题 I've worked on VS projects before where there is no .designer.cs files. Now I started a new project on a different computer and I can't get rid of designer.cs files. It's really annoying me. Do I really need it, how can I remove it? There must be a setting somewhere. 回答1: You're dealing with a web application rather than a website (clarification) Yes, in the context of a web application, you do need them. 回答2: YES! You can remove them......here is how..... HOW TO DELETE DESIGNER.CS PAGES FROM

Workaround for VB.NET partial method using CodeDom?

阅读更多关于 Workaround for VB.NET partial method using CodeDom?

问题 I know CodeDom doesn't support partial methods, but is there a workaround? I found a workaround for C#, but I need one for VB.NET. Thanks. 回答1: It is a horrible hack, as wicked as the C# one, but it does work: Imports System.CodeDom Imports System.CodeDom.Compiler Imports System.IO Module Module1 Sub Main() Dim unit As New CodeCompileUnit Dim nspace As New CodeNamespace("SomeNamespace") Dim vbclass As New CodeTypeDeclaration("SomeClass") vbclass.IsClass = True Dim snippet As New

Why you need partial methods in c#? Can events be used to achieve the same goal?

阅读更多关于 Why you need partial methods in c#? Can events be used to achieve the same goal?

I was reading the book "Apress Pro LINQ: Language Integrated Query in C#" and I came across partial methods, but I really don't understand what is the need for them. I think the examples in the book (properties before and after change) can be implemented using events. So any explanation? Yes, you could achieve a similar effect with events as you can with partial methods. Partial methods are really just a way of letting code generators, primarily designers, to generate hooks for the non-generated code. Events could fill this role. However there are advantages to partial methods over events in
