c sharp 中调用mo如何解决引用问题?

本文提供了一种解决.NET SDK安装过程中遇到的问题的方法。通过编辑注册表中的特定条目,可以确保正确安装.NET SDK并使某些应用程序能够正常工作。具体步骤包括定位注册表中的指定路径、复制相关路径值、创建新的注册表条目并设置相应的值。

Step 1: Run "REGEDIT" from the Command Prompt or the Windows "Start | Run..." menu item and navigate to this key: HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/.NETFramework In this key are a few different values on the right-side panel, one of them is named "sdkInstallRootv1.1". The value to the right of this name is the absolute path on your machine's disk where "bin/gacutil.exe" is stored. In a typical default installation of .NET, the path in this key's value might look something like this: "C:/Program Files/Microsoft Visual Studio .NET 2003/SDK/v1.1/"

Step #2: In the right side panel of the Registry Editor, left-click to select the "sdkInstallRootv1.1" in the "Name" column. Then go up to the "Edit" menu and select "Modify", which will open a new smaller window called "Edit String".

Step #3: In the "Edit String" window, use your mouse to highlight and select the entire contents of the "Value Data" text box, then use [Ctrl] + C to copy that string to the clipboard. Then hit the "Cancel" button to dismiss this "Edit String" window.

Step #4: Go back to the left panel of the Registry Editor panel and left-click on the ".NETFramework" key to select it. Then go to the "Edit" menu and select "New...", which opens a menu to the right in which you should choose the menu item which says "String Value".

Step #5: A new entry will be made in the "Name" column of the right panel of the Registry Editor called "New Value #1" ready to edit. Change its name to "sdkInstallRoot". If it won't let you edit the name, then right-click on "New Value #1" and select "Rename" from the popup menu, then type in the new name "sdkInstallRoot" and hit [Enter] to make the name change.

Step #6: Right-click on your new name "sdkInstallRoot", and select "Modify" from the popup menu. Single-click your mouse into the text box below "Value Data", then use [Ctrl] + V to paste in the path string which you copied into the clipboard back in Step #3 above. Then click the OK button to finish the edit and dismiss the small "Edit String" window.

大体翻译:打开注册表(在windows开始的运行中键入regedit),打开(找到)HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/.NETFramework 这一项,新建一个字符值"sdkInstallRoot”,为这个字符值修改数据为字符值为"sdkInstallRootv1.1"的数据值.我成功了,然后安装MO2.2,MO2.2的SDK .net的支持选项就可选安装了 

在 CefSharp 中,C# 调用 JavaScript 方法是通过 `EvaluateScriptAsync` 或 `ExecuteJavaScriptAsync` 方法实现的,这些方法允许从 C# 代码中执行嵌入在网页中的 JavaScript 代码,并获取返回结果。以下是具体的实现方式: ### 1. 使用 `EvaluateScriptAsync` 方法调用 JavaScript 方法并获取返回值 此方法用于执行 JavaScript 表达式并获取返回结果。例如,调用一个名为 `jsFunction` 的 JavaScript 函数,并传递参数。 ```csharp var browser = new ChromiumWebBrowser(); browser.LoadUrl("http://example.com"); // 等待页面加载完成 browser.FrameLoadEnd += async (sender, args) => { if (args.Frame.IsMain) { // 调用 JavaScript 函数并传递参数 var response = await browser.EvaluateScriptAsync("jsFunction('Hello from C#')"); if (response.Success && response.Result != null) { var result = response.Result.ToString(); Console.WriteLine("JavaScript 返回结果: " + result); } } }; ``` ### 2. 使用 `ExecuteJavaScriptAsync` 方法调用 JavaScript 方法 此方法适用于不需要返回值的 JavaScript 调用,通常用于执行脚本而不关心返回结果。 ```csharp browser.ExecuteJavaScriptAsync("document.getElementById('myElement').style.color = 'red';"); ``` ### 3. 调用 JavaScript 方法并传递复杂参数 如果需要传递复杂参数(如 JSON 对象),可以使用字符串拼接的方式构造 JavaScript 表达式。 ```csharp string param = "{ name: 'John', age: 30 }"; var script = $"jsFunctionWithObject({param});"; await browser.EvaluateScriptAsync(script); ``` ### 4. 调用 JavaScript 方法并处理异步结果 如果 JavaScript 方法返回的是一个 Promise,可以通过 `await` 等待结果。 ```csharp var script = "async function callAsync() { return await Promise.resolve('Async Result'); } callAsync();"; var response = await browser.EvaluateScriptAsync(script); if (response.Success && response.Result != null) { var result = response.Result.ToString(); Console.WriteLine("异步 JavaScript 返回结果: " + result); } ``` ### 5. 调用 JavaScript 方法并处理异常 在调用 JavaScript 时,可能会遇到脚本执行错误,因此需要处理异常情况。 ```csharp try { var response = await browser.EvaluateScriptAsync("nonExistentFunction()"); if (!response.Success) { Console.WriteLine("JavaScript 执行失败: " + response.Message); } } catch (Exception ex) { Console.WriteLine("发生异常: " + ex.Message); } ``` ### 总结 CefSharp 提供了多种方式实现 C# 调用 JavaScript 方法的功能,包括同步和异步调用、传递参数、处理返回值及异常等。通过 `EvaluateScriptAsync` 和 `ExecuteJavaScriptAsync` 方法,可以灵活地与网页中的 JavaScript 交互[^1]。 ---
