[removed] What is the simplest way to format a string?

Question

I have the following format: Value1 is {0} and Value2 is {1}.

I need to replace the numbers in the brackets with strings. This is easily done in most languages usin

Answer 1

I wanted something similar and didn't like any of these answers as they meant multiple lines for each value (Ignoring Beaner's answer is for the wrong language!) so I created the following:

Public Function StrFormat(FormatString, Arguments())
    Dim Value, CurArgNum

    StrFormat = FormatString

    CurArgNum = 0
    For Each Value In Arguments
        StrFormat = Replace(StrFormat, "{" & CurArgNum & "}", Value)
        CurArgNum = CurArgNum + 1
    Next
End Function

You can use the following then (note that you need to add "Array()" around your variables):

formatString = "Test '{0}', '{2}', '{1}' and {0} again!"
Response.Write StrFormat(formatString, Array(1, 2, "three", "Unused"))
Response.Write StrFormat(formatString, Array(4, 5, "six", "Unused"))

Which will output what you expect:

Test '1', 'three', '2' and 1 again!
Test '4', 'six', '5' and 4 again!

Hope this feels a bit more natural for people from other languages.
