文档管理软件，文档管理系统，知识管理系统，档案管理系统的技术资料：
以下C#代码是自动从Excel文件提取数据（表格）并自动生成Html页面表格。
关键点一：
引用准确的控件(需要安装完整版本的OFFICE 2003)，或安装OFFICE 2003 PIA模块（联高软件>FileBone有链接）。
关键点二：
using System;
using System.IO;
using System.Text;
using System.Text.RegularExpressions;
using System.Collections;
// 这句话需要特别注意哦！
using Excel = Microsoft.Office.Interop.Excel;
namespace Legalsoft.Basic
{
public class Office_Interface
{
private static string Excel2Html(string fileName)
{
StringBuilder sb = new StringBuilder();
if (!File.Exists(fileName)) return “没有找到“ + fileName + “文件!“;
sb.AppendLine(“<!DOCTYPE HTML PUBLIC \“-//W3C//DTD HTML 4.0 Transitional//EN\“>“);
sb.AppendLine(“<html>“);
sb.AppendLine(“<head>“);
sb.AppendLine(“<title>“ + fileName + “</title>“);
sb.AppendLine(“<meta http-equiv=\“content-type\“ content=\“text/html; charset=gb2312\“ />“);

{

if (ws == null) break;
int rowCount = ws.UsedRange.Rows.Count;
int colCount = ws.UsedRange.Columns.Count;

for (int i = 0; i < rowCount; i++)
{
sb.AppendLine(“<tr>“);
for (int j = 0; j < colCount; j++)
{
