        // now send it
        requestStream.Write(postBytes, 0, postBytes.Length);

        // grab te response and print it out to the console along with the status code
        WebResponse response = await request.GetResponseAsync();

推荐答案

WebView类不支持直接使用POST参数导航到URL.

WebView class doesn't support navigating to an URL with POST parameters directly.

但是，您可以使用代码和WebResponse来获取HTML.然后使用WebView类的NavigateToString方法呈现HTML:

You could however use your code and the WebResponse to get the HTML. And then use the NavigateToString method of the WebView class to render the HTML:

            HttpWebResponse httpResponse= (HttpWebResponse)response;
            StreamReader reader=new StreamReader(httpResponse.GetResponseStream());
            string htmlString= reader.ReadToEnd();
            if (!string.IsNullOrEmpty(htmlString))
                webView.NavigateToString(htmlString);

或者您可以使用带有您的帖子值的表单和一些JavaScript来创建自己的HTML，以提交表单，但这可能会比较麻烦.

Or you could create your own HTML with a form with your post values and some javascript to submit the form, but that might be a bit more cumbersome.
