Answer 1

using System; 
using System.Collections.Generic; 
using System.Text; 
using System.Data; 
using Excel;
using System.IO;
using System.Reflection;namespace ohmygod 
{ 
   public class SqlToExcel 
    { 
        public void ValueToExcel(object Value,string ExcelColNum,string ExcelRowNum,string FilePath) 
        { 
            object oMissing = System.Reflection.Missing.Value; 
            Excel.ApplicationClass xlApp = new Excel.ApplicationClass(); 
            try 
            { 
                xlApp.Visible = false; 
                xlApp.DisplayAlerts = false; 
                Excel.Workbooks oBooks = xlApp.Workbooks; 
                Excel._Workbook xlWorkbook = null;                 xlWorkbook = oBooks.Open(FilePath, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, 
        oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing); 
                Excel.Worksheet xlWorksheet = xlWorksheet = (Excel.Worksheet)xlWorkbook.Worksheets.get_Item(1); 
                xlWorksheet.Activate();                 string RangeNum = ExcelColNum + ExcelRowNum; 
                Excel.Range r = xlWorksheet.get_Range(RangeNum, RangeNum);                 r.Value2 = Value;                 r.EntireColumn.AutoFit();                 xlWorkbook.Save(); 
  
            } 
            catch 
            { 
                throw; 
            } 
            finally 
            { 
                xlApp.Quit(); 
                foreach (System.Diagnostics.Process p in System.Diagnostics.Process.GetProcesses()) 
                { 
                    if (p.MainModule.ModuleName == "EXCEL.EXE") 
                    { 
                            p.Kill(); 
                            break; 
                    } 
                } 
            } 
        }     } 
} 这个是使用的方法
