Here are a couple of examples of using Excel with C#:

This example sends a value to cell A1 of a Microsoft Office Excel 2003 worksheet.

public void EchoStringToCell(string str)
{
    Excel.Worksheet sheet1 =
        (Excel.Worksheet)this.ThisApplication.Sheets.get_Item(1);
    ((Excel.Range)sheet1.Cells[1,1]).Value2 = str;
}

This example uses the Add method of the ChartObjects collection to add a chart to a Microsoft Office Excel 2003 worksheet programmatically.

public void CreateChart()
{
    Excel.Worksheet thisWorksheet;
    thisWorksheet = thisWorkbook.ActiveSheet as Excel.Worksheet;
    Excel.ChartObjects charts = 
        (Excel.ChartObjects)thisWorksheet.ChartObjects(Type.Missing);

    // Adds a chart at x = 100, y = 300, 500 points wide and 300 tall.
    Excel.ChartObject chartObj = charts.Add(100, 300, 500, 300);
    Excel.Chart chart = chartObj.Chart;

    // Gets the cells that define the bounds of the data to be charted.
    Excel.Range chartRange = thisWorksheet.get_Range("A5","D8");
    chart.SetSourceData(chartRange,Type.Missing);

    chart.ChartType = Excel.XlChartType.xlXYScatter;
    Excel.SeriesCollection seriesCollection= 
        (Excel.SeriesCollection)chart.SeriesCollection(Type.Missing);
    Excel.Series series = seriesCollection.Item(seriesCollection.Count);
}

This example requires:
Data to be charted, stored in the range from A5 to D8 in the worksheet.

Not sure if this is what you were looking for.

i think it's hard to do appending data to excel file,
if possible i could write it on text file or CSV file just like this:

NAME ID
name1 001
name2 002
