Question

I have a list of array List<float[]> and I want to create excel file so i can email the arrays for testing. I need it in excel and not XML – serialization will not do here.
I want to have each array in its own worksheet(tab) – here CSV goes out of the window 🙁

Can someone guide me what is the best approach for achieving it? using Microsoft.Office.Interop.Excel seems like overkill for my needs but if this is the best way i would appreciate a sample on how to do it.

Thanks.

Using Interop is probably the simplest thing to do.

If l is your list:

    Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
    xlApp.Visible = true;
    xlApp.Workbooks.Add(misValue);
    int nWS = xlApp.ActiveWorkbook.Worksheets.Count;
    for (int i = nWS; i < l.Count; i++)
        xlApp.ActiveWorkbook.Worksheets.Add(misValue, misValue, misValue, misValue);
    int iWS = 1;
    foreach (float[] ff in l)
    {
        Microsoft.Office.Interop.Excel.Worksheet ws = (Microsoft.Office.Interop.Excel.Worksheet)xlApp.ActiveWorkbook.Worksheets[iWS++];
        int idxRow = 1;
        foreach (float aFloat in ff)
            ws.Cells[idxRow++, 1] = aFloat;
    }
