首先 创建Windows窗体应用程序
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace _03_浏览器控件 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { string text = textBox1.Text; Uri uri = new Uri("http://"+text);//创建uri对象,为了调用其构造函数(构造函数只有在创建对象的时候才会被调用) webBrowser1.Url = uri; } } }
