mrtig has a very elegant solution. But it won't work if you have the workbooks in separate instances of excel. So, the key is to open them in just one instance. I've modified your example to show using this approach:

public void CopyRanges()
{
    // only one instance of excel
    Excel.Application excelApplication = new Excel.Application();

    srcPath="C:\\Documents and Settings\\HARRY\\Desktop\\incident.csv";
    Excel.Workbook srcworkBook = excelApplication.Workbooks.Open(srcPath);
    Excel.Worksheet srcworkSheet = srcworkBook.Worksheets.get_Item(1);

    destPath = "C:\\Documents and Settings\\HARRY\\Desktop\\FIXED Aging incident Report.xls";
    Excel.Workbook destworkBook = excelApplication.Workbooks.Open(destPath,0,false);
    Excel.Worksheet destworkSheet = destworkBook.Worksheets.get_Item(1);

    Excel.Range from = srcworkSheet.Range("C1:C100");
    Excel.Range to = destworkSheet.Range("C1:C100");

    // if you use 2 instances of excel, this will not work
    from.Copy(to);

    destworkBook.SaveAs("C:\\Documents and Settings\\HARRY\\Desktop\\FIXED Aging incident Report " + DateTime.Now.ToString("MM_dd_yyyy") + ".xls");
    srcxlApp.Application.DisplayAlerts = false;
    destxlApp.Application.DisplayAlerts = false;
    destworkBook.Close(true, null, null);
    srcworkBook.Close(false, null, null);
    excelApplication.Quit();
}
