How to create an array during runtime?

[VBCrazyCoder]

You would still have to declare your array, then in a loop when you are iterating your files, you would dynamically reinstantiate an array and add it to the original array (using redim preserve or using an arraylist).

You could do something like:

Dim arrAllFilesData As New ArrayList
Dim arrTempSingleFileData As ArrayList
 
            For intFileCount As Integer = 0 To 100
 
                'Set your file stuff here
 
                'Reinstantiate the array
                arrTempSingleFileData = New ArrayList
 
                For intFileLineCount As Integer = 0 To 100
                    'iterating your file line by line
                    arrTempSingleFileData.Add("Some File Text Here")
                Next
 
                'Add the single file array to the main array
                arrAllFilesData.Add(arrTempSingleFileData)
            Next

so for each file you would be reusing the arrTempSingleFileData arraylist as many times as you need to.
