如何在C#中写Excel文件

1. 创建一个Console Application, 添加COM选显卡中的Microsoft Excel 12.0 Object Library引用.

2. 粘贴下面的源代码.

using System;

using Excel = Microsoft.Office.Interop.Excel;



namespace CShartExcelTest

{

    class Program

    {

        static void Main(string[] args)

        {

            try

            {

                string[,] values = { 

                                             {"Tom",   "18",  "Beijing",     "13912345678"},

                                             {"Jerry",  "17",  "Shanghai",  "13687654321"}

                                        };

                Excel.Application objApp;

                Excel._Workbook objBook;

                Excel.Workbooks objBooks;

                Excel.Sheets objSheets;

                Excel._Worksheet objSheet;

                Excel.Range range;



                // Instantiate Excel and start a new workbook.

                objApp = new Excel.Application();

                objBooks = objApp.Workbooks;

                objBook = objBooks.Add(System.Reflection.Missing.Value);

                objSheets = objBook.Worksheets;

                objSheet = (Excel._Worksheet)objSheets.get_Item(1);



                //Get the range where the starting cell has the address

                range = objSheet.get_Range("A2", System.Reflection.Missing.Value);

                range = range.get_Resize(2, 4);

                range.set_Value(System.Reflection.Missing.Value, values);



                //Construct the header.

                objSheet.Cells[1, 1] = "Name";

                objSheet.Cells[1, 2] = "Age";

                objSheet.Cells[1, 3] = "HomeTown";

                objSheet.Cells[1, 4] = "Mobile";



                bool bSave = false;



                if (bSave)

                {

                    //Return control of Excel to the user.

                    objApp.Visible = true;

                    objApp.UserControl = true;

                }

                else

                    objBook.SaveAs(@"c:\temp\csharp-Excel.xls",

                        Excel.XlFileFormat.xlWorkbookNormal,

                    releaseObject(objBook);

                    releaseObject(objApp);

                }

            }

            catch (Exception ex)

            {

                Console.WriteLine(ex.Message);
