Clearing two-dimensional array

I am using a two-dimensional array of 10 elements, but my code is extremely slow.

Dim myArray As String(,) 
For i=0 to 100
   'Clear Array. (This line is really slow)
   myArray = New String(,) {{"", ""}, {"", ""}, {"", ""}, _
   {"", ""}, {"", ""}, {"", ""}, {"", ""}, {"", ""}, {"", ""}, {"", ""}}

   'Populate array
   fillArray(myArray) 

   'Do stuff with array
   useArray(myArray)
Next i

I 开发者_StackOverflow社区create a new empty array with every iteration of the for loop. Is there a way I can use the same array but just clear it instead?

It's unclear what you're using your array for, but you might want to look into using a collection instead.

As far as clearing the array is concerned, look into using Array.Clear.

Doesn't vb.net have a way to quickly create 2 dimensional arrays? It was something like:

Dim rectArray(10, 10) As String

Then you can populate as usual:

Dim rectArray(,) As String = {{'', '', '' ....etc
