Subject: NVelocity String Functions - Split
Print | Individual message | Show original | Report this message | Find messages by this author
I am using the NVelocity view engine with the latest ASP.NET MVC
framework, preview 3. I cannot figure out how to split a comma
delimited string. Here is what I am trying and it is not working.

#set($myString = "one,two,three,four")

#foreach($str in $myString.Split(","))
  $str
#end

I am not sure why this is not working. I can get substring and replace
to work just fine. What is wrong with split? What references should I
be using to see what string functions are available? I have tried the
VTL reference.

Thanks.

Why not use:

#set( $numbers = ["one", "two", "three","four"] )

#foreach( $str in $numbers)
        $str
#end

I've never used NVelocity with ASP.NET MVC, but I don't know if it is
possible call the Split method from your variable $myString. One
possible reason is that $myString is not created by NVelocity as a
normal C# string. Have you tried do the same with a variable passed
from controller?

Cheers,

José,

Thanks for the help. I do not have an array as you used in your
example. I have a string that is comma delimited.

#set( $numbers = ["one", "two", "three","four"] ) = array
#set( $numbers ="one,two,three,four") = my comma delimited string

Since I have a string delimited by commas, I need to use split to
create an array to iterate over. I am not sure why split does not
appear to work, nor am I sure what reference documentation I should be
using. For example, is this just VTL documentation, or is this Java
string documentation, or C# strings, ect. The Java docs have a string
util function called split, that I tried that. Then I tried the C#
version of split, and nothing worked there.

Thanks again for any ideas,

Alex

From here http://msdn.microsoft.com/en-us/library/system.string.split.aspx
it looks like there's no overload for a string, only char and string
arrays. so it's not finding the overload, and that's why it's not
working

Thanks for the help, both of you. I have moved forward, without the
split, passing the array to my view as needed. Split would sure be
useful in that case.
