Answer 1

You can use the 'Path' property to get the right path.

private void WorkbookSaveAs()
{
    if (this.FileFormat == Excel.XlFileFormat.xlWorkbookNormal)
    {
        this.SaveAs(this.Path + @"\XMLCopy.xls",
        Excel.XlFileFormat.xlXMLSpreadsheet, missing, missing,
        false, false, Excel.XlSaveAsAccessMode.xlNoChange,
        missing, missing, missing, missing, missing);
}
}

Hope this helps!

        System.Runtime.InteropServices.Marshal.ReleaseComObject(xlWorkBook);
        System.Runtime.InteropServices.Marshal.ReleaseComObject(xlWorkSheet);
        System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);
