	    1 增加应用   Microsoft.Office.Interop.Excel
	    2 引用命名空间 using Excel = Microsoft.Office.Interop.Excel;
	    /// <summary>
	 /// If the supplied excel File does not exist then Create it
	 /// </summary>
	 /// <param name="FileName"></param>
	 private void CreateExcelFile(string FileName)
	 {
	 //create
	 object Nothing = System.Reflection.Missing.Value;
	 var app = new Excel.Application();
	 app.Visible = false;
	 Excel.Workbook workBook = app.Workbooks.Add(Nothing);
	 Excel.Worksheet worksheet = (Excel.Worksheet)workBook.Sheets[1];
	 worksheet.Name = "Work";
	 //headline
	 worksheet.Cells[1, 1] = "FileName";
	 worksheet.Cells[1, 2] = "FindString";
	 worksheet.Cells[1, 3] = "ReplaceString";

	 worksheet.SaveAs(FileName, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing);
	 workBook.Close(false, Type.Missing, Type.Missing);
	 app.Quit();
	 }

	 /// <summary>
	 /// open an excel file,then write the content to file
	 /// </summary>
	 /// <param name="FileName">file name</param>
	 /// <param name="findString">first cloumn</param>
	 /// <param name="replaceString">second cloumn</param>
	 private void WriteToExcel(string excelName,string filename,string findString,string replaceString)
	 {
	 //open
	 object Nothing = System.Reflection.Missing.Value;
	 var app = new Excel.Application();
	 app.Visible = false;
	 Excel.Workbook mybook = app.Workbooks.Open(excelName, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing);
	 Excel.Worksheet mysheet = (Excel.Worksheet)mybook.Worksheets[1];
	 mysheet.Activate();
	 //get activate sheet max row count
	 int maxrow = mysheet.UsedRange.Rows.Count + 1;
	 mysheet.Cells[maxrow, 1] = filename;
	 mysheet.Cells[maxrow, 2] = findString;
	 mysheet.Cells[maxrow, 3] = replaceString;
	 mybook.Save();
	 mybook.Close(false, Type.Missing, Type.Missing);
	 mybook = null;
	 //quit excel app
	 app.Quit();
	 }
