有没有办法在.Net 3.5中用委托来做到这一点? [英] Is there a way to do this with delegates in .Net 3.5?

问题描述

我们有一个系统，需要动态更改一组步骤结束时发生的情况.我们正在使用委托进行此操作.但是，我们需要在步骤集末尾调用的方法具有不同的签名.目前，我们可以选择使用标准委托人签名(可能是从ASP.Net复制事件处理程序)来执行此操作，还是以其他方式来执行此操作(确定！).有没有办法在.Net 3.5中用委托来做到这一点?还是我们可以使用C#4.0的命名参数或委托中的可选参数来做到这一点?

解决方案

我们通过使用事件处理程序方法签名来解决此问题，即我们的委托期望(对象发送者，eventargs e)，并构建了一个自定义事件args类./p>

We have a system where we need to dynamically change what happens at the end of a set of steps. We're doing this using a delegate. However the methods that we need to call at the end of the set of steps have different signatures. We have a choice at the moment to either do this using a standard delegate signature (probably copying the event handler one from ASP.Net) or doing it some other way (undertermined!) Is there a way to do this with delegates in .Net 3.5 ? Or could we do this using C# 4.0's named parameters or optional parameters on the delegate?

解决方案

We got around this by using the event handler method signature, i.e. our delegate expects (object sender, eventargs e) and we built a custom event args class.
