通過這個軟件一兩天就完成了幾千產品數據的錄入，可見很多工作不是一味用人工去做，作為一個程序員，就是要讓很多讓那些經常做重復性的、繁瑣的工作中的人解放出來。下面只是寫了一些核心代碼，而且采集必須要和對應網站相掛鉤，作者：鄭少群
代碼如下:
//提取產品列表頁中產品最終頁的網頁
private void button1_Click(object sender, EventArgs e)
{
if (textBox1.Text.Trim() == "" || textBox2.Text.Trim() == "")
{
MessageBox.Show("網址和域名不能為空！", "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
return;
}
try
{
string Html = inc.GetHtml("http://study.pctoday.net.cn");
//ArrayList al = inc.GetMatchesStr(Html, "<a[^>]*?>.*?</a>");
ArrayList al = inc.GetMatchesStr(Html, @"href/s*=/s*(?:[/'/""/s](?<1>[^/""/']*)[/'/""])");//提取鏈接
" title="Replica Watches:">Replica Watches Buy Full Quality Popular Luxury Watches at Amazing Price, Your One Stop Discount Swiss Watches StoreExclusive Replica Rolex Watches, Tag Heuer Watches Replica, Cartier Watches online Sale!
StringBuilder sb = new StringBuilder();
foreach (object var in al)
{
string a = var.ToString().Replace("/"", "").Replace("'", "");
a = Regex.Replace(a, "href=", "", RegexOptions.IgnoreCase | RegexOptions.Multiline);
if (a.StartsWith("/"))
a = textBox2.Text.Trim() + a;
if (!a.StartsWith("http://"))
a = "http://" + a;
sb.Append(a + "/r/n");
}
textBox5.Text = sb.ToString();//把提取到網址輸出到一個textBox，每個鏈接占一行
MessageBox.Show("共提取" + al.Count.ToString() + "個鏈接", "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (Exception err)
{
MessageBox.Show("提取出錯！原因：" + err.Message, "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
//把采集的產品頁面html代碼進行字符串處理，提取需要的代碼，最后保存到本地一個access數據庫中，同時提取產品圖片地址并自動現在圖片到本地images文件夾下
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
//填充產品表
Database.ExecuteNonQuery("delete from Tb_Product");
DataTable dt2 = new DataTable();
OleDbConnection conn = new OleDbConnection(Database.ConnectionStrings);
OleDbDataAdapter da = new OleDbDataAdapter("select * from Tb_Product", conn);
OleDbCommandBuilder cb = new OleDbCommandBuilder(da);
da.Fill(dt2);
dt2.Rows.Clear();
BackgroundWorker worker = (BackgroundWorker)sender;//這個是做一個進度條
string[] Urls = textBox5.Text.Trim().ToLower().Replace("/r/n", ",").Split(',');
DataTable dt = new DataTable();
StringBuilder ErrorStr = new StringBuilder();
string html = "", ImageDir = AppDomain.CurrentDomain.BaseDirectory + "Images//";
//循環每次采集網址
