C#中关于访问Internet以及自制浏览器的方法

1.访问Internet

测试代码如下：

System.Net.WebClient Client = new WebClient();
Stream strm = Client.OpenRead("http://www.sina.com.cn");
StreamReader sr = new StreamReader(strm);
string line;
while ((line = sr.ReadLine()) != null)
{
    System.Console.WriteLine(line);
}

strm.Close();

 

2.自制简易浏览器

代码如下：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace Browser{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void webBrowser1_DocumentTitleChanged(object sender, EventArgs e) { this.Text = webBrowser1.DocumentTitle.ToString(); } private void textBox1_KeyPress(object sender, KeyPressEventArgs e) { if (e.KeyChar == (char)13) { webBrowser1.Navigate(textBox1.Text); } } private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e) { textBox1.Text = webBrowser1.Url.ToString(); } private void Form1_Load(object sender, EventArgs e) { buttonBack.Enabled = false; buttonForward.Enabled = false; buttonStop.Enabled = false; } private void buttonBack_Click(object sender, EventArgs e) { webBrowser1.GoBack(); textBox1.Text = webBrowser1.Url.ToString(); } private void buttonForward_Click(object sender, EventArgs e) { webBrowser1.GoForward(); textBox1.Text = webBrowser1.Url.ToString(); } private void buttonStop_Click(object sender, EventArgs e) { webBrowser1.Stop(); } private void buttonHome_Click(object sender, EventArgs e) { webBrowser1.GoHome(); textBox1.Text = webBrowser1.Url.ToString(); } private void buttonRefresh_Click(object sender, EventArgs e) { webBrowser1.Refresh(); } private void buttonSubmit_Click(object sender, EventArgs e) { webBrowser1.Navigate(textBox1.Text); } private void webBrowser1_CanGoBackChanged(object sender, EventArgs e) { if (webBrowser1.CanGoBack == true) { buttonBack.Enabled = true; } else { buttonBack.Enabled = false; } } private void webBrowser1_CanGoForwardChanged(object sender, EventArgs e) { if (webBrowser1.CanGoForward == true) { buttonForward.Enabled = true; } else { buttonForward.Enabled = false; } } private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e) { buttonStop.Enabled = true; } private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { buttonStop.Enabled = false; } }}
