将文本值从WinCE C＃App传递到WebApp

Question

我有在WinCE上运行的RFID手持设备。 供应商为我提供了一个简单应用程序的源代码，该应用程序从扫描的RFID标签读取RFID代码并将其显示在应用程序本身中（Windows窗体）。 我需要以某种方式使此值达到我的Web应用程序的最低要求，而无需通过POST，GET方法或打开新的IE窗口。 谢谢你的指教。

您可以轻松地创建一个WebRequest对象并将其发布到网页上：

http://msdn.microsoft.com/zh-CN/library/debx8sh9.aspx

// Create a request using a URL that can receive a post. 
WebRequest request = WebRequest.Create ("http://www.contoso.com/PostAccepter.aspx ");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "This is a test that posts this string to a Web server.";
byte[] byteArray = Encoding.UTF8.GetBytes (postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams.
reader.Close ();
dataStream.Close ();
response.Close ();
