我能够调用 WebBrowser.ObjectForScripting 用JavaScript C＃方法 window.external 从 web浏览器的WinForms控制，并通过字符串， INT ，布尔等，但我不知道如何通过JavaScript的日期对象，并以某种方式转换/元帅到.NET 日期时间类。

I am able to call C# methods of WebBrowser.ObjectForScripting with javascript window.external from WebBrowser WinForms control and pass string, int, bool etc. However I don't know how to pass javascript Date object and somehow convert/marshal it to .NET DateTime class.

很显然，我可以通过一个字符串并解析它，但是这是真的不是重点。我只是好奇，我怎么能做到这一点的JavaScript 日期和.NET 的DateTime ？

Obviously, I could pass a string and parse it, but this is really not the point. I'm just curious how could I do it with javascript Date and .NET DateTime?

推荐答案

我终于得到了它的工作。我不知道为什么，但我无法使用它与动态。这里是解决方案：

I finally got it working. I don't know why, but I am unable to use it with dynamic. Here is the solution:

[ComVisible(true)]
public class Foo
{
    public void Bar(object o)
    {
        var dateTime = (DateTime)o.GetType().InvokeMember("getVarDate", BindingFlags.InvokeMethod, null, o, null);
        Console.WriteLine(dateTime);
    }
}
