Jetbrains全系列IDE使用 1年只要46元 售后保障 童叟无欺

1.点击“引用”，右键”管理Nuget程序包”，搜索框里输入”CefSharp”，选择”CefSharp.WinForms”，安装。

 这样就会自动把CefSharp需要的拓展给安装齐全了，之后在解决方案的 packages 目录里会有4个文件夹 cef.redist.x64.版本号，cef.redist.x86.版本号，CefSharp.Common.版本号，CefSharp.WinForms.版本号。

2.使用代码：

using CefSharp.WinForms;
using Microsoft.Win32;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Security.Cryptography;
using System.Text;
using System.Windows.Forms;
using ZKKC.Lib;

namespace Wb
{
    public partial class FormMain : Form
    {
        private CefSharp.WinForms.ChromiumWebBrowser wb_main;
        delegate void SetWebBrowserVisible(Boolean result);

        public FormMain()
        {
            InitializeComponent();

        }

        /// <summary>
        /// 初始化WebBrowser
        /// </summary>
        public void InitWb()
        {

            String url = "https://ie.icoa.cn/";

            this.wb_main = new CefSharp.WinForms.ChromiumWebBrowser(url);
            this.wb_main.ActivateBrowserOnCreation = false;
            this.wb_main.Dock = System.Windows.Forms.DockStyle.Fill;
            this.wb_main.Location = new System.Drawing.Point(0, 0);
            this.wb_main.Name = "wb_main";
            this.wb_main.Size = new System.Drawing.Size(800, 450);
            this.wb_main.TabIndex = 0;
            this.wb_main.FrameLoadStart += new System.EventHandler<CefSharp.FrameLoadStartEventArgs>(this.wb_main_FrameLoadStart);
            this.wb_main.FrameLoadEnd += new System.EventHandler<CefSharp.FrameLoadEndEventArgs>(this.wb_main_FrameLoadEnd);
            this.pl_main.Controls.Add(this.wb_main);

            try
            {
                this.toToggleWbVisible(false);  //直接设置Visible=false,会导致浏览器不会访问地址，所以在访问底之前手动设置为不可见
                this.wb_main.Load(url);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
                throw e;
            }
        }
        
        private void FormMain_Load(object sender, EventArgs e)
        {
            //初始化WebBrowser
            InitWb();
        }
        
        /// <summary>
        /// 修改浏览器插件的可见性
        /// </summary>
        /// <param name="result"></param>
        private void toToggleWbVisible(Boolean result)
        {
            // InvokeRequired required compares the thread ID of the
            // calling thread to the thread ID of the creating thread.
            // If these threads are different, it returns true.
            if (this.wb_main.InvokeRequired)
            {
                SetWebBrowserVisible d = new SetWebBrowserVisible(toToggleWbVisible);
                this.Invoke(d, new object[] { result });
            }
            else
            {
                this.wb_main.Visible = result;
            }
        }

        /// <summary>

        private void wb_main_FrameLoadStart(object sender, CefSharp.FrameLoadStartEventArgs e)
        {

            if (!e.Url.Equals("about:blank"))
            {
