推荐答案

您可以使用设备门户REST API进行禁用屏幕键盘，这里有一个你可以参考的样本：

You can use device portal REST API for disable on-screen keyboard, here is a sample you can reference:

            string uri = "http://[IP ADDRESS]:8080/api/iot/osk/settings?IsFollowInputFocusEnabled=false";

            string data = "";
            byte[] dataBytes = Encoding.UTF8.GetBytes(data);

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
            request.ContentLength = dataBytes.Length;
            request.ContentType = "application/x-www-form-urlencoded";
            request.Method = "POST";
            CredentialCache myCache = new CredentialCache();
            myCache.Add(new Uri("http://[IP ADDRESS]:8080"), "Basic", new NetworkCredential("Administrator", "p@ssw0rd"));
            request.Credentials = myCache;

            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            using (Stream stream = response.GetResponseStream())
            using (StreamReader reader = new StreamReader(stream))
            {
                string answer = reader.ReadToEnd();
                Console.WriteLine("status code:" + response.StatusCode.ToString());
                Console.WriteLine("result:" + answer);
            }

祝你好运，
