How to get the size of an array?

Hello,

I have this for loop:

For i = 1 to 10
....
Next

I want to use the size of an array instead of 10.

How to determine the size of an array?

Thanks,
Miguel

Dim myArray As String() = New String() { "This", "is", "a", "string",
"array" }

For i = 0 To myArray.GetUpperBounds(0)
' Do something.
Next

NOTE: Can't remember if GetUpperBounds returns a 0 based index...it
probably does so you may need myArray.GetUpperBounds(0) - 1 instead.

For i = 0 to UBound(MyArray)-1
....
Next

hmmm, I think "Ubound" no need to -1

I think you do need it.
it's zero based.

When you use the ubound(array) in VB.net, it gives you the upper index of
the array, nothing to do with Zero based. such as
dim a as string() = {"A","B","C","D","E"}
ubound(a) will give you 4, same as in VB 6.0. Therefore, just to know the
size, it is better to use the length. It gives you 5. Just remember to "-1"
when you use it in a loop.

Do you get your mcsd in C#?

You are right.
I was confusing it with Array.Length, in which case the "-1" should be used.
