问题
I am trying to implement this example
http://blog.evonet.com.au/post/Gridview-with-highlighted-search-results.aspx
but the only problem I am facing is the AddressOf keyword of VB.net which I am unable to convert in C#.net
can anybody help me out with this, what alternative I should use to make it work.
Thanks.
Edit: I found some searches on stackoverflow regarding similar problems but I am unable to understand them.
回答1:
You can just leave it out. Method groups are implicitly convertible to delegates in C#.
return ResultStr.Replace(InputTxt, new MatchEvaluator(ReplaceWords))
Or even simpler(I think this requires C# 2):
return ResultStr.Replace(InputTxt, ReplaceWords);
But since ReplaceWords
is so simple, I'd consider a lambda expression(Requires C# 3):
return ResultStr.Replace(InputTxt, m => "<span class=highlight>" + m + "</span>");

Based on the link you posted, I'm assuming that you want this:
Return ResultStr.Replace(InputTxt, New MatchEvaluator(AddressOf ReplaceWords))
.. in C#?
If so you don't need the AddressOf
keyword at all. MatchEvaluator
is a delegate type so you can simply pass over a method (ResultStr.Replace(InputTxt, ReplaceWords)
). Alternatively, you could use an anonymous method for this to reduce the code, which makes sense as it's not being used elsewhere:
return ResultStr.Replace(InputTxt, delegate(Match m) {
return "<span class=highlight>" + m.ToString() + "</span>";
});

I think you need to translate this into:
new EventHandler(theMethod)
回答4:
You should be able to use something like this:
return ResultStr.Replace(InputTxt, new MatchEvaluator(ReplaceWords))
Basically, in c# you don't need the 'addressOf' operator. I like having it, since it makes it real clear whats up, but c# is just like that.
