替换system.windows.forms.webbrowser用Microsoft.web.webview2.winforms.webview2 in winforms应用程序

Question

我正在使用Microsoft.web.webview2.winforms.webview2升级Winforms C＃.NET 4.8 Framework应用程序并替换嵌入式浏览器System.Windows.Forms.webbrowser。我正在调用我的C＃代码中一些浏览器托管的JavaScript函数，而且我的JavaScript函数确实调用了一些C＃方法。 我已经使它工作了（信息源之一是文章 https://weblog.west.west-wind.com/posts/2021/jan /14/toth-the-new-chromium-webview2-control-a-a-spin-in-net-net-part-1＃do-you-need-the-webview2 ），但是，我不是对我的代码中的序列化/避难所感到满意。令我困扰的是，交换是基于序列化的字符串。这种方法对我来说似乎有些原始。要调用JavaScript函数，我正在撰写一个源语句。另一方面，当我的浏览器脚本调用C＃方法时，该参数是一个序列化的字符串（我知道是JSON格式化的），所有引用字符都逃脱了。

我的问题是：我是否应该以不同的方式意识到C＃和JavaScript之间的相互作用？

这是我从winforms测试程序中使用JavaScript调用的两个C＃代码片段，我为应对迁移而制作的：

public struct ConfigGraph3D
{
    public bool showServices { get; set; }
    public string viewStyle { get; set; }
    public bool enforceNodeLabels { get; set; }
    public bool enforceServiceLabels { get; set; }
    public bool planesVisible { get; set; }
    public bool embedded { get; set; }
}
// retrieving a JavaScript structure into a C# structure
//var CONFIG = { showServices: true, viewStyle: "O", enforceNodeLabels: false, 
//               enforceServiceLabels: false, planesVisible: true, embedded: false};
//
string invocation = "getConfig()";
string response = await browser.ExecuteScriptAsync(invocation);
// Notice here that I’m deserializing the data twice: first removing backslash escapes
// then converting it into the structure ConfigGraph3D.
string configStr = JsonSerializer.Deserialize<string>(response);
ConfigGraph3D config = JsonSerializer.Deserialize<ConfigGraph3D>(configStr);
textConfig.Text = response;
//
// sending a graph structure to JavaScript. 
// The properly formatted JSON structure is read from a file by yet it needs to be serialized 
// in order to add escape characters (backslash).
//
string invocation = getJsonFile (graphFilePath) ;
string response = await browser.ExecuteScriptAsync(invocation);
//
//
string getJsonFile (string graphFilePath)
{
    string contents = File.ReadAllText(graphFilePath);
    JsonSerializerOptions jso = new JsonSerializerOptions();
    jso.Encoder = System.Text.Encodings.Web.JavaScriptEncoder.UnsafeRelaxedJsonEscaping;
    string contents2 = JsonSerializer.Serialize(contents, jso);
    string invocation = "replaceModelList(" + contents2 + ")";
    return invocation;
}

从JavaScript中调用C＃：

    public struct ItemSelectedInfo
    {
        public int id { get; set; }
        public string type { get; set; }
    }
    //
    // invoked from JavaScript 
    // var jsonObj = "{ \"id\": " + mesh._id2 + ", \"type\":\"" + mesh._type + "\"}";   
    // window.chrome.webview.hostObjects.sync.dotnet.SelectedinGraphic(jsonObj);
    //
    [ComVisible(true)]
    public class GraphInterface
    {
        public void SelectedinGraphic(string jsonInfo)
        {
            ItemSelectedInfo selectedNodeKey = JsonSerializer.Deserialize<ItemSelectedInfo>(jsonInfo);
            Debug.WriteLine("SelectedinGraphic: " + jsonInfo);
        }
    }
