How to copy one Excel file to another using spreadsheet light in VB.NET?

Question

I have a code wherein I am taking two files. Both are Excel files and I need to copy one file to another. The number of rows and columns in the files are dynamic.

sFile is the source file and sFile1 is the destination file. I need to know the number of rows in source file to run a for loop when am copying it to destination file.

The code is below:

Dim shtlight As New SLDocument(sFile1) 
Dim lrow As Integer 
Dim lcol As Integer 
Dim sflie = Environment.Directory & "\Data.xls" 
lrow = 2  
Dim shtlight1 As New SLDocument(sFile1) 

For each row in sfile1 
    for column in sfile1 'code here to set value next next

I want help in running this for loop, don't know how to set the upper bound as no of rows and columns in file is dynamic.

Can someone help please? I am using phone so format might not be correct. :(

As I mentioned in the comments above, I have never worked with SpreadsheetLight . I just downloaded SpreadsheetLight and experimented with it.

To get the last row you need to use this

Imports DocumentFormat.OpenXML
Imports DocumentFormat.OpenXML.Spreadsheet
Imports SpreadsheetLight

Public Class Form1

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim sl As New SLDocument("C:\Users\Siddharth\Desktop\Tester.xlsx", "Sheet1")
        MessageBox.Show (sl.GetWorksheetStatistics.EndRowIndex)
    End Sub
End Class

Note

For someone who is novice like me to SpreadsheetLight and would like to experiment.

1. Reference set to DocumentFormat.OpenXml.dll ( Open XML SDK 2.0 ). Can be downloaded from Here . It didn't work with Open XML SDK 2.5 for me and I didn't put too much into it to find out to why...

2. Reference set to SpreadsheetLight. Can be downloaded from Here

Above code is tested on VS 2013
