Array Function for ASP - 19 Feb 2002

I was in search of an array function like the one below for ASP (being so lazy!), but I couldn't find one... so I decided to create my own! This function reads a file line by line and stores each line a dynamic array. First two object varibles - fso (file system object) and ts (textfileobject) - are created.

Set fso = CreateObject("Scripting.FileSystemObject")
Set ts = fso.OpenTextFile(filename, ForReading)

Then I declared an array using ReDim statement with the size set one.

reDim myarray(0)

Now as long as I read from the file, I change the size of the array dynamically without destroying the previous elements and copy the current line read to the current array element.

While not ts.AtEndOfStream
i=i+1

Redim Preserve myarray(i)
myarray(i)=ts.ReadLine
Wend

The final statement returns the myarray object from function File(filename). Here's the entire source code listing:
