If you don't know the size of an array when you create it (and it
needs to be available to the whole program), is it more efficient to
redim or use (,) e.g. :
1.
Public class form1
….
Dim SampleArray(,) as string
…
Private sub Something()
Dim NowWeKnowTheValueOfTheArray as integer = 100
Dim NowWeKnowTheValueOfTheArray2 as integer = 1000
For i = 0 to NowWeKnowTheValueOfTheArray - 1
For j = 0 to NowWeKnowTheValueOfTheArray2 - 1
SampleArray(i, j) = "Something"
next
Next
Or
2.
Public class form1
…..
Dim SampleArray(0,1) as string
…..
Private sub Something()
Dim NowWeKnowTheValueOfTheArray as integer = 100
Dim NowWeKnowTheValueOfTheArray2 as integer = 1000
Redim SampleArray(NowWeKnowTheValueOfTheArray - 1 ,
NowWeKnowTheValueOfTheArray2 - 1)
For i = 0 to NowWeKnowTheValueOfTheArray - 1
For j = 0 to NowWeKnowTheValueOfTheArray2 - 1
SampleArray(i, j) = "Something"
next
Next
Or something else? 1 1310
It is best to use an ArrayList object that can grow as you need it.
You can set an initial size.
