WPF+CEF 执行JS报错

WPF+CEF 执行JS报错

在WPF中执行 webBrowser.EvaluateScriptAsync("window.scrollBy(0, 1000);");

在部分网站会报异常：
Request BrowserId : XXXX not found it's likely the browser is already closed

---

环境

.Net Framework 4.7

CefSharp.Wpf 131.3.50

解决方案：

使用CEF的控制台去执行

// xaml 页面
<cef:ChromiumWebBrowser x:Name="webBrowser" />

//using CefSharp.Wpf;

public static async Task<ResultInfo> GetEvaluateJsAsync(ChromiumWebBrowser webBrowser, string js)
{
    var res = new ResultInfo() { Success = false };
    try
    {
        if (webBrowser == null || webBrowser.IsDisposed)
            return res;

        var client = webBrowser.GetDevToolsClient();
        if (client == null)
            return res;

        var result = await client.Runtime.EvaluateAsync(js, null, true, null, null, true, null, true);
        if (result == null || result.ExceptionDetails != null)
            return res;
        res.Result = result.Result.Value?.ToString();
        res.Success = true;
        return res;
    }
    catch (Exception ex)
    {
        res.Result = ex.Message;
        return res;
    }
}

 public class ResultInfo
 {
     public bool Success { get; set; }
     public string Result { get; set; }
 }
