VS 2010 declare/dimension multiple object using for, possible?

forse mi sono espresso male

i have to declare multiple ojject, in this particular case streamreader/writer whitout declare all manually

for i=0 to 50
dim variablename(i can use i value too) as new streamreader(Application.StartupPath & "\temp\" & i & ".txt")
next

but i got error, is possible in another way?

Dim sw As New StreamWriter(Application.StartupPath & "\temp\0.txt", True)
Dim sw1 As New StreamWriter(Application.StartupPath & "\temp\1.txt", True)
Dim sw2 As New StreamWriter(Application.StartupPath & "\temp\2.txt", True)
