var uri = new Uri("http://localhost/SOAP/SOAPSMS.asmx/add");
var req = (HttpWebRequest) WebRequest.CreateDefault(uri);
req.ContentType = "text/xml; charset=utf-8";
req.Method = "POST";
req.Accept = "text/xml";
req.Headers.Add("SOAPAction", "http://localhost/SOAP/SOAPSMS.asmx/add");
var strSoapMessage = @"<?xml version='1.0' encoding='utf-8'?>
<soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
<soap:Body><add xmlns='http://tempuri.org/'><a>23</a><b>5</b></soap:Body>
</soap:Envelope>";
using (var stream = new StreamWriter(req.GetRequestStream(), Encoding.UTF8))
stream.Write(strSoapMessage);

I've done something like this, building an xml request manually and then using the webrequest object to submit the request:
我做过这样的事情，手动构建一个 xml 请求，然后使用 webrequest 对象提交请求：
string data = "the xml document to submit";
string url = "the webservice url";
string response = "the response from the server";
// build request objects to pass the data/xml to the server
byte[] buffer = Encoding.ASCII.GetBytes(data);
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = buffer.Length;
Stream post = request.GetRequestStream();
// post data and close connection
post.Write(buffer, 0, buffer.Length);
post.Close();
// build response object
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
Stream responsedata = response.GetResponseStream();
StreamReader responsereader = new StreamReader(responsedata);
response = responsereader.ReadToEnd();
The string variables at the start of the code are what you set, then you get a string response (hopefully...) from the server.
代码开头的字符串变量是您设置的，然后您会从服务器获得字符串响应（希望...）。

This isn't the normal way. Usually you would use WCF or the older style web service reference to generate a proxy client for you.
这不是正常的方式。通常您会使用 WCF 或旧样式的 Web 服务引用来为您生成代理客户端。
However, what you need to do generally is use HttpWebRequest to connect to the URL and then send the XML in the body of the request.
但是，您通常需要做的是使用 HttpWebRequest 连接到 URL，然后在请求正文中发送 XML。

I'm wondering how's the XML generated and is it a valid SOAP message? You can post it via HTTP as suggested by the folks above.
我想知道 XML 是如何生成的，它是否是有效的 SOAP 消息？您可以按照上述人员的建议通过 HTTP 发布它。
If you want to test if that's going to work, you can give SoapUIa try (for testing I mean).
如果你想测试它是否会起作用，你可以试试SoapUI（我的意思是测试）。

Here's another example--this one in VB:
这是另一个例子——这个在 VB 中的例子：
Dim manualWebClient As New System.Net.WebClient()
manualWebClient.Headers.Add("Content-Type", "application/soap+xml; charset=utf-8")
' Note: don't put the <?xml... tag in--otherwise it will blow up with a 500 internal error message!
Dim bytArguments As Byte() = System.Text.Encoding.ASCII.GetBytes( _
"<soap12:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap12=""http://www.w3.org/2003/05/soap-envelope"">" & System.Environment.NewLine & _
" <soap12:Body>" & System.Environment.NewLine & _
" <Multiply xmlns=""http://cptr446.class/"">" & System.Environment.NewLine & _
" <x>5</x>" & System.Environment.NewLine & _
" <y>4</y>" & System.Environment.NewLine & _
" </Multiply>" & System.Environment.NewLine & _
" </soap12:Body>" & System.Environment.NewLine & _
"</soap12:Envelope>")
Dim bytRetData As Byte() = manualWebClient.UploadData("http://localhost/CPTR446.asmx", "POST", bytArguments)
MessageBox.Show(System.Text.Encoding.ASCII.GetString(bytRetData))

Sorry for bumping an old thread here's my solution to this
很抱歉碰到旧线程，这是我的解决方案
''' <summary>
''' Sends SOAP to a web service and sends back the XML it got back.
''' </summary>
Public Class SoapDispenser
Public Shared Function CallWebService(ByVal WebserviceURL As String, ByVal SOAP As String) As XmlDocument
Using wc As New WebClient()
Dim retXMLDoc As New XmlDocument()
wc.Headers.Add("Content-Type", "application/soap+xml; charset=utf-8")
retXMLDoc.LoadXml(wc.UploadString(WebserviceURL, SOAP))
Return retXMLDoc
End Using
End Function
End Class

You need to post the data over HTTP. Use the WebRequest classto post the data. You will need to send other data with the post request to ensure you have a valid SOAP envelope. Read the SOAP specfor all of the details.
您需要通过 HTTP 发布数据。使用WebRequest 类发布数据。您将需要随 post 请求发送其他数据，以确保您拥有有效的 SOAP 信封。阅读SOAP 规范以了解所有详细信息。
