C# CefSharp如何在Winforms应用程序中使用

最近做了一个很小的功能,在网页上面打开应用程序,用vs的debug调试,可以正常打开应用程序,可布置到iis上面却无法运行应用程序,吾百度之,说是iis权限问题,吾依理做之,可怎么折腾也不行。最后boss给了两种方案,第一,弃b/s改c/s,第二,用CefSharp把b/s网站嵌进去。b/s网站已做完,弃之可惜,吾便用了CefSharp。

以下是使用CefSharp的步骤:

 1.创建一个基本的Winforms应用程序,并添加CefSharp使用NuGet包。

    在创建之前,请确保计算机已安装:CefSharp 45.0及更高版本需要安装VC 2013 Redistributable Package x86,早期版本需要VC 2012 Redistributable Package x86。如果未安装,会报以下错误。

  An unhandled exception of type 'System.IO.FileNotFoundException' occurred in browser.exe Additional information: Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies.

    通常安装最新版本的CefSharp,建议完全关闭VS,然后重新打开(这样可以确保您的引用显示,并有完整的intellisense),否则你可能会发生错误:找不到类型或命名空间名称“Cefsharp”(是否缺少using指令或程序集引用?)

2 更改平台配置(x86,x64或AnyCPU)

   吾用的CefSharp版本是51以上,所以要修改配置:

   首先,搜索your-project-name.csproj文件,并在第一个 <PropertyGroup>的节点添加:

     <CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport>

   然后修改app.config文件:

     <runtime>

    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <probing privatePath="x86"/>
    </assemblyBinding>
 </runtime>
3 cefsharp已经安装并配置完成,现在就可以写代码了.
  这是winfrom的代码
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CefSharp;
using CefSharp.WinForms;
using System.Configuration;

namespace VR.Winfrom
{
    public partial class Form1 : Form
    {
        public ChromiumWebBrowser chromeBrowser;

        public Form1()
        {
            InitializeComponent();
            this.WindowState = FormWindowState.Maximized;
            InitializeChromium();
            // Register an object in javascript named "cefCustomObject" with function of the CefCustomObject class :3
            chromeBrowser.RegisterJsObject("formProcess", new FormProcess(chromeBrowser, this));
        }

        public void InitializeChromium()
        {
            CefSettings settings = new CefSettings();
            // Initialize cef with the provided settings
            Cef.Initialize(settings);
            // Create a browser component
            string url = ConfigurationManager.AppSettings["Url"];
            chromeBrowser = new ChromiumWebBrowser(url);

            // Add it to the form and fill it to the form window.
            this.Controls.Add(chromeBrowser);
            chromeBrowser.Dock = DockStyle.Fill;

            // Allow the use of local resources in the browser
            BrowserSettings browserSettings = new BrowserSettings();
            browserSettings.FileAccessFromFileUrls = CefState.Enabled;
            browserSettings.UniversalAccessFromFileUrls = CefState.Enabled;
            browserSettings.WebSecurity = CefState.Enabled;
            chromeBrowser.BrowserSettings = browserSettings;
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            Cef.Shutdown();
        }
    }
}
这是执行应用程序的代码
using System.Diagnostics;
using CefSharp.WinForms;
using VR.DAL;
using System;

namespace VR.Winfrom
{
   public class FormProcess
    {
        // Declare a local instance of chromium and the main form in order to execute things from here in the main thread
        private static ChromiumWebBrowser _instanceBrowser = null;
        // The form class needs to be changed according to yours
        private static Form1 _instanceMainForm = null;
        
        public FormProcess(ChromiumWebBrowser originalBrowser, Form1 mainForm)
        {
            _instanceBrowser = originalBrowser;
            _instanceMainForm = mainForm;
        }

        public void opencmd(string filePath)
        {
              
                string file = @"" + filePath;
                ProcessStartInfo start = new ProcessStartInfo(file);
                Process.Start(start);
        }

       
    }
}

最后web页面的调用

<button class="btn btn-primary" onclick="FormProcess.opencmd('C://Program Files (x86)//Google//Chrome//Application//chrome.exe');">Open</button>
