Android Question [solved]add "-" in string

[ronell]

dim number as string = "123"

how can i add hyphen after each char ? i need to get something like this

number = 1-2-3

iterate over the string transferring chars and hyphens into a stringbuilder, then get the result with stringbuilder.tostring

'-'.join(number)
(Damn!! I think Python spoiled me... )

Dim number = "123" As String
Dim output = number.CharAt(0) As String
For i = 1 To (number.Length - 1)
    output = output & "-" & number.CharAt(i)
Next
Log (output)

Using stringbuilder (which is supposed to be faster for string appends):

Dim number = "123" As String
Dim output as stringbuilder
output.append(number.CharAt(0))
For i = 1 To (number.Length - 1)
    output.append("-" & number.CharAt(i))
Next
Log (output.tostring)

single line version

log(Regex.Replace("\d","123","-$0").SubString(1))
