System.Net.WebUtility.HtmlDecode似乎没有正常工作

Question

这是我的客户端代码（WinForm的C＃桌面）：

sb.Append("<informedworker>"); 
sb.Append("<request name=\"Customer\" action=\"GET\" verb=\"*\">"); 
sb.Append("</request>"); 
sb.Append("</informedworker>"); 
Uri url = new Uri("http://192.168.0.6/DATA_START" + System.Net.WebUtility.HtmlEncode(sb.ToString()) + "DATA_END"); 
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
      request.Method = "GET"; 
using (var response = request.GetResponse()) 
using (var stream = response.GetResponseStream()) 
using (var reader = new StreamReader(stream)) 
{ 
    HttpStatusCode statusCode = ((HttpWebResponse)response).StatusCode; 
    string contents = reader.ReadToEnd(); 
} 

这在我的服务器应用程序的代码，这在UWP应用C＃：

StringBuilder request = new StringBuilder(); 
using (IInputStream input = args.Socket.InputStream) 
{ 
    byte[] data = new byte[BufferSize]; 
    IBuffer buffer = data.AsBuffer(); 
    uint dataRead = BufferSize; 
    while (dataRead == BufferSize) 
    { 
     await input.ReadAsync(buffer, BufferSize, InputStreamOptions.Partial); 
     request.Append(Encoding.UTF8.GetString(data, 0, data.Length)); 
     dataRead = buffer.Length; 
    }      
} 
System.Diagnostics.Debug.WriteLine(System.Net.WebUtility.HtmlDecode(request.ToString())); 

，这是结果：

GET /DATA_START<informedworker><request%20name="Customer"%20action="GET"%20verb="*"></request></informedworker>DATA_END HTTP/1.1 
Host: 192.168.0.6 
Connection: Keep-Alive 

，你可以看到 '<' 和 '>' AR e转换成OK，但空格仍然被读为％20？

从我看到的，HtmlDecode方法使用HtmlEntities静态类，其中有实体列表解码。但没有提及空间特征。你可能想尝试调用Uri.UnescapeDataString（）来代替。
