C# 使用webbrowser解析html网站中的文本？

C# 使用webbrowser解析html网站中的文本？,c#,webbrowser-control,C#,Webbrowser Control,我想创建一个访问票证管理系统网站的表单，以便在windows表单应用程序中，在一些文本框中，显示创建人：、票证标题、创建地点等信息。我尝试将过滤器设置为从某一行开始： var ticketLines = codes.Where(m => m.StartsWith("<TD style=\"WIDTH: 65px; HEIGHT: 22px; LEFT: 110px\" class=hb-table-cell>")); 为此，我创建了一个列表，在其中我将发布我需要的某些信息：

我想创建一个访问票证管理系统网站的表单，以便在windows表单应用程序中，在一些文本框中，显示创建人：、票证标题、创建地点等信息。我尝试将过滤器设置为从某一行开始：

var ticketLines = codes.Where(m => m.StartsWith("<TD style=\"WIDTH: 65px; HEIGHT: 22px; LEFT: 110px\" class=hb-table-cell>"));

为此，我创建了一个列表，在其中我将发布我需要的某些信息：

List<string> ticketTitles = new List<string>();
            foreach (string line in ticketLines)
            {   
                //select the line from which you want to start scrapping
                int y = codes.IndexOf(line);
                //ticket title
                ticketTitles.Add(codes[y + 1].Substring(codes[y + 1].IndexOf(">") + 1, codes[y + 1].Length - codes[y + 1].IndexOf(">") - 6));
                //created at
                ticketTitles.Add(codes[y+2].Substring(codes[y+2].IndexOf(">")+1, codes[y+2].Length - codes[y+2].IndexOf(">") - 6 )); 
            }

在我的表单中，我有一个“登录”按钮和一个“生成”按钮。“生成”按钮通过输入特定票据id激活页面

到目前为止，我的进展是创建了自动登录按钮，没有这个按钮，您无法以特定票号进入网站

如何在文本框中显示我的元素？有人能给我解释一下这个过程吗？有人试图帮助我并将此表单中的所有代码保存到txt中：

            //textBox1.Text= this.webBrowser1.Document.Window.Frames[2].Document.GetElementsByTagName("input").Count.ToString();

            var ticketLines = codes.Where(m => m.StartsWith("<TD style=\"WIDTH: 65px; HEIGHT: 22px; LEFT: 110px\" class=hb-table-cell>"));

            //create list in which will store the text filtered
            List<string> ticketTitles = new List<string>();
            foreach (string line in ticketLines)
            {   
                //select the line from which you want to start scrapping
                int y = codes.IndexOf(line);
                //ticket title
                ticketTitles.Add(codes[y + 1].Substring(codes[y + 1].IndexOf(">") + 1, codes[y + 1].Length - codes[y + 1].IndexOf(">") - 6));
                //created at
                ticketTitles.Add(codes[y+2].Substring(codes[y+2].IndexOf(">")+1, codes[y+2].Length - codes[y+2].IndexOf(">") - 6 )); 
            }



            //int x = 1;

        }

我怎样才能复制这段代码呢。这似乎与在铬合金中使用检查元件不同？或者，我该如何在这方面做得更进一步

谢谢大家!

你的问题是什么？你的意思是你想生成一个新的表单，还是你已经有了一个表单，你只想提取一些InnerHtml值放在你已经创建的表单中？我不太清楚你在这里想要实现什么。您可以使用简单的WebApi来实现这一点，或者更难的方法是序列化和提取innerHtml。我不推荐。是的，我已经有了一个表单，但是当我尝试将过滤后的信息传递到texbox时，它不会显示任何内容

using System.Threading;
namespace snippet
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {

            this.webBrowser1.Navigate("https://elvis.harman.com/");

            while (this.webBrowser1.ReadyState != WebBrowserReadyState.Complete)
            {
                Thread.Sleep(100);
                Application.DoEvents();
            }

            //textBox1.Text= this.webBrowser1.Document.Window.Frames[2].Document.GetElementsByTagName("input").Count.ToString();


            this.webBrowser1.Document.Window.Frames[2].Document.GetElementsByTagName("input")[0].InnerText = textBox1.Text;
            this.webBrowser1.Document.Window.Frames[2].Document.GetElementsByTagName("input")[1].InnerText = textBox2.Text;
            this.webBrowser1.Document.Window.Frames[2].Document.GetElementsByTagName("button")[0].InvokeMember("click");

            //MessageBox.Show("Done!");


        }

        private void button2_Click(object sender, EventArgs e)
        {
            this.webBrowser1.Navigate("https://elvis.harman.com/cgi-bin/ticket?TID=" + txtID.Text);
            Thread.Sleep(2000);
            //this.webBrowser1.Navigate("https://elvis.harman.com/cgi-bin/ticket?TID=" + txtID.Text);
            //Thread.Sleep(2000);

            this.webBrowser1.Update();
            //var b = this.webBrowser1.Document.GetElementById("ticketHeader").InnerHtml;

            // txtTitle.Text =  this.webBrowser1.Document.GetElementById("field_100");
            var codes = this.webBrowser1.Document.GetElementById("gridBox").InnerHtml.Split(Environment.NewLine.ToCharArray(), StringSplitOptions.RemoveEmptyEntries).Select(m => m.Trim()).ToList();

            //search in code for the line that starts with " "
            var ticketLines = codes.Where(m => m.StartsWith("<TD style=\"WIDTH: 65px; HEIGHT: 22px; LEFT: 110px\" class=hb-table-cell>"));

            //create list in which will store the text filtered
            List<string> ticketTitles = new List<string>();
            foreach (string line in ticketLines)
            {   
                //select the line from which you want to start scrapping
                int y = codes.IndexOf(line);
                //ticket title
                ticketTitles.Add(codes[y + 1].Substring(codes[y + 1].IndexOf(">") + 1, codes[y + 1].Length - codes[y + 1].IndexOf(">") - 6));
                //created at
                ticketTitles.Add(codes[y+2].Substring(codes[y+2].IndexOf(">")+1, codes[y+2].Length - codes[y+2].IndexOf(">") - 6 )); 
            }



            //int x = 1;

        }
