我正在使用HttpWebRequest发送Xml作为流但我收到以下响应：“prolog中不允许内容”

我应该使用编码UTF-16BE，但我不知道如何。

我目前的代码：

 private void sendXml(string protocolo, string path)
    {
        string base64 = Convert.ToBase64String(Encoding.Default.GetBytes("user:password"));
        string authorization = String.Concat("Basic ", base64);

        String finalResult;
        HttpWebRequest hwrRequest = (HttpWebRequest)HttpWebRequest.Create("https://address/"+protocolo);

        hwrRequest.UseDefaultCredentials = true;
        hwrRequest.Headers.Add("Authorization", authorization);
        hwrRequest.Method = "PUT";

        string finalXML = @"<?xml version=""1.0"" encoding=""UTF-16BE""?>....";

        byte[] bytes = Encoding.BigEndianUnicode.GetBytes(finalXML);

        hwrRequest.ContentLength = bytes.Length;

        using (Stream putStream = hwrRequest.GetRequestStream())
        {
            putStream.Write(bytes, 0, bytes.Length);
        }

        using (HttpWebResponse response = (HttpWebResponse)hwrRequest.GetResponse())
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            finalResult = reader.ReadToEnd();
            visualiza.Text = visualiza.Text + "\n " + finalResult;
        }
    }

生成xmlDocument的方法

private void geraXML()
    {

        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.PreserveWhitespace = false;
        byte[] xml = Encoding.BigEndianUnicode.GetBytes(@"<?xml version=""1.0"" encoding=""UTF-16BE""?>...");

        MemoryStream ms = new MemoryStream(xml, true);
        xmlDoc.Load(ms);
        string caminho = path/+"xmldoc.xml";            
        string nomeArquivo = "xmldoc.xml";
        xmlDoc.Save(caminho);                      

        geraHASH(caminho, nomeArquivo);            
    }

Encoding班级有 - BigEndianUnicode

获取使用大端字节顺序的UTF-16格式的编码。

因此，您可以更改代码以使用它（而不是ASCII

        string finalXML = @"<?xml version=""1.0"" encoding=""UTF-16BE""?>";

        byte[] bytes = Encoding.BigEndianUnicode.GetBytes(finalXML);
