Format function doesn't work in ASP.NET?

Ok... I have a string that contains "1" ... I want to format it so that it will hold "00000001"

So I just do...

s1 = "1"
s2 = Format(s1, "00000000")

s2 now equals "00000000" ... when it should be "00000001"

This works in regular VB, but not ASP.NET .... WHY?!

Well, for starters, ASP.NET <> VB.

Try this:

VB Code:

Dim s1 As String = "1"
Dim s2 As String = s1.PadLeft(8, "0")

I realize this is way after the fact, but the reason this didn't evaulate correctly is due to namespace operations.

First, ASP.NET, when Language = VB IS VB.Net.

The reason this doesn't work right off is that the namespace resolution engine does not know which FORMAT to use and uses the wrong one.

Instead of
s2 = Format(s1, "00000000")
use
s2 = String.Format(s1, "00000000")

Since the Format object you were looking for is the Format object of the String class.

While I'm at it, I might as well point out that the way you are doing it will be deprecated some time in the future. (Microsoft never gives estimates)

They now recommend:

s2 = Double.Parse(s1).ToString("00000000")
