最近做了一個很小的功能，在網頁上面打開應用程序，用vs的debug調試，可以正常打開應用程序，可布置到iis上面卻無法運行應用程序，吾百度之，說是iis權限問題，吾依理做之，可怎麽折騰也不行。最後boss給了兩種方案，第一，棄b/s改c/s，第二，用CefSharp把b/s網站嵌進去。b/s網站已做完，棄之可惜，吾便用了CefSharp。

以下是使用CefSharp的步驟：

1.創建一個基本的Winforms應用程序，並添加CefSharp使用NuGet包。

在創建之前，請確保計算機已安裝：CefSharp 45.0及更高版本需要安裝VC 2013 Redistributable Package x86，早期版本需要VC 2012 Redistributable Package x86。如果未安裝，會報以下錯誤。

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.

通常安裝最新版本的CefSharp，建議完全關閉VS，然後重新打開（這樣可以確保您的引用顯示，並有完整的intellisense），否則你可能會發生錯誤：找不到類型或命名空間名稱“Cefsharp”（是否缺少using指令或程序集引用？）

2 更改平臺配置（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，並在第一個 <PropertyGroup>的節點添加：

<CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport>

然後修改app.config文件:

<runtime>

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();
        }
    }
}

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);
        }

       
    }
}

最後web頁面的調用

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