Trouble Using System.Array.ForEach

[Nathan Sokalski]

I am trying to use the System.Array.Fo rEach method in VB.NET. The action
that I want to perform on each of the Array values is:

Private Function AddQuotes(ByVal value As String) As String
Return String.Format(" '{0}'", value)
End Function

Basically, I just want to surround each value with single quotes. However, I
am having trouble getting this to work using the System.Array.Fo rEach
method. This may be partially because I am not very experienced with Actions
or Delegates, so if somebody could tell me what I am doing wrong, I would
appreciate it. Thanks. (NOTE: The Array that I want to modify the values of
is not one that I have permission to modify (it is
System.Globaliz ation.DateTimeF ormatInfo.Curre ntInfo.DayNames ()), so if
anybody knows of a way to do this inline without declaring another Array,
that would be nice as well)

RE: Trouble Using System.Array.Fo rEach

The Action type for the ForEach method requires a subroutine that takes no
parameters. I've never tried this method, but it doesn't seem useful for
your situation. How about starting with the following:


For Each dayofweek As String In _
System.Globaliz ation.DateTimeF ormatInfo.Curre ntInfo.DayNames

Console.Out.Wri teLine(AddQuote s(dayofweek))
Next

Re: Trouble Using System.Array.Fo rEach

That would get me the quotes around each of the days, but I was hoping to do
something like this:

String.Join("," ,System.Globali zation.DateTime FormatInfo.Curr entInfo.DayName s())

so that I could have the DayNames separated by commas. However, the code
that I have above would not place each day inside quotes. Do I know of ways
to create this comma-delimited String? Of course, but using a for loop would
require me to either include an if statement determining when I am at the
last value or manually remove the comma from the end of the String. I
figured if I could just use the String.Join instead, I wouldn't have to deal
with so many Strings and If statements. And, even though it may be just a
thirst for knowledge, I would like to know how to use the ForEach method for
future reference. Thanks.

Re: Trouble Using System.Array.Fo rEach

This will avoid the leading comma:


dim n as integer = CurrentInfo.Day Names.Length - 1
dim s as string = CurrentInfo.Day Names(0)

for i = 1 to n
s = string.Format(" {0}, {1}", s, CurrentInfo.Day Names(i))
next

Re: Trouble Using System.Array.Fo rEach

I know how to do string manipulation, that is a very simple task. However,
in several of my cases I want to not only add quotes to each element, but
take the substring of it as well (for example, in some cases I want an array
of only the first letter of each day). The techniques people have mentioned
so far are great when I want the entire name, but when I need to do
something like get just the first letter, or if I want it in all capitals,
etc., I would require either a loop of some sort (which is what I am trying
to avoid) or the ForEach method. I appreciate everyone's suggestions on how
to use loops and string manipulation, but unfortunately (well, fortunately
actually) I already know those techniques. So unless you are going to help
me figure out how to use ForEach, save yourself the effort of showing me
string manipulation and help someone else that is still learning loops and
all the string manipulation techniques. But I still thank you for your time
and effort.

Re: Trouble Using System.Array.Fo rEach

It appeared from your last question, that you thought using a loop to build
the comma separated list would require an if-then clause to remove the comma
before the first iteration. The code I provided eliminates this.

You have shown several cases where you seem to want a solution "of a
particular form", rather than a solution. Perhaps someone can post an
example where Array.ForEach solved a problem for them, but to be honest with
you, I have never run into a case where it helped. I think if someone has an
example, it won't exactly fit your conditions.

Re: Trouble Using System.Array.Fo rEach

You are definitely correct that you proved me wrong about the loop thing, at
least for the scenario of simply adding quotes, thank you very much for
providing that solution. However, I still have the scenarios where I need to
use only the first letter, or the first two letters, or capitalize, etc.,
and your solution does not work for these (unless I'm missing something
again), which I think are the scenarios I was thinking about when I
mentioned the If Then statement. And you may be right about the ForEach not
fitting my conditions, I really can't say for sure since I have never had
the opportunity to use ForEach, but either way, it never hurts to have extra
knowledge so that if a situation were to come up where it was fit I would
know it. Thanks.

The Action type for the ForEach method requires a subroutine that
takes
no
parameters. I've never tried this method, but it doesn't seem
useful
for
your situation. How about starting with the following:

Re: Trouble Using System.Array.Fo rEach

I have nothing against loops, in fact in many cases, I try to use them to if
it can reduce the size of my code, but in this case, I could end up removing
both a loop and an if-then, as well as some string manipulation. So in this
case, I think the ForEach would shrink my code more than a loop. I feel
loops are very important and useful, but in this case I think I could do
better, as well as the fact that I want to learn certain things, and not
everything is included in the books I have (and I have a reasonable number,
and have read them cover to cover). I appreciate any and all help you can
give.

What is so evil about using a loop?
