Yield Keyword in VB.NET 2.0

What the heck - I can't find it. A bit shocked to see it missing though.

So "Does VB.NET have the yield keyword, or any equivalent of it" ?

Sahil,

Please to give better posibilities to research and therefore a better
product, use this newsgroups for Net 2.0 and related products.

Cor,

I checked that place - no help there.

I must say, I am incredibly frustrated and very annoyed that something as
important as the "yield" keyword would be missed out of VB.NET.

Now try writing a SQLCLR TVF and the 3 lines it takes to accomplish it in C#
translate to 3 pages of buggy VB.NET code. Highly Highly Highly Highly
stupid to miss that out IMO.

Sahil,

I think that this reaches where you are looking for. This old Visual Basic
keyword is probably one of the reasons why what is in C language called
Static is called in VBNet Shared.

Cor,

I'm not talking about "Static/Shared" .. I am talking about "Yield".

No. Different languages have different features.

Sahil,
I'm not talking about "Static/Shared" .. I am talking about "Yield".

I assume that you do not know what Static is in VBNet, therefore I gave you
the link to the page.

If you want a mercedes with a chevrolet logo, than you have to put that logo
on it yourself, Mercedes does not do that for you.

However I find the Mercedes logo is not bad at all

static d as integer
For each a in b
d += 1
Next

This gives you at the end of your program the total result of loops or if
you set it conditional to zero let you go on where you was in the loop.

I am not busy with 2005, however short reading gave me the idea that this
was the idea.

I hope this helps,

Cor

yield is a keyword which is only valid in custom enumerator routines
('iterators'), something which is C# 2.0 only if I'm not mistaken. It's
therefore logical VB.NET doesn't have a yield equivalent, as it doesn't
support custom iterator creation (though it's my understanding it does
support consuming them). At least, that's my understanding, but I might
have overlooked something.

Therefore, babbling about static/shared is erm... completely
irrelevant ;)

yield is a keyword for custom iterators, which IMHO is something
which is C# only.

However, it's not hard to work around it. After all, we all write code
today which works OK right? :)
