How do I dynamically resize an array? Take for example a program that reads and stores a series of strings from a file, but you don`t know how many strings there will be.

Not real code!!

dim test() as string
dim loop as integer = 0

while !endofFile
{
test(loop)=readStringFromFile
loop=loop+1
redim test(loop)
}

However redim destorys the perivous data. So how do I grow the size of the array at runtime?

Thanks
