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>
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>
