VB.net to C# Equivalent of “AddressOf”

Question

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.

Answer 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>");

Answer 2

I think you need to translate this into:

new EventHandler(theMethod)

Answer 3

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>";
});

Answer 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.
