手动调用安全 WCF 服务

我需要手动调用WCF（通过HttpWebRequest）。我可以通过添加 Web 引用并通过代理调用它来调用我的服务，因此我知道服务设置正确，证书、Web 配置等都是正确的。根据我找到的示例，我认为我做对了，但仍然收到内部错误 500。

编辑：WebService正在使用wsHttpBinding。

控制台应用代码为：

    HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:8733/Design_Time_Addresses/WcfServiceLibrary1/Service1");
    string strRequest = Properties.Resources.TextFile1;
    req.Method = "POST";
    req.ContentType = "application/soap+xml; charset=utf-8";
    req.ContentLength = strRequest.Length;
    req.Credentials = new NetworkCredential("test", "test");
    using (Stream stream = req.GetRequestStream())
    {
        stream.Write(UTF8Encoding.Default.GetBytes(strRequest), 0, strRequest.Length);
    }
    using (WebResponse res = req.GetResponse())
    {
        // nothing to do here
    }

文本文件1 是 XML 请求...现在只是硬编码：

<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
  <s:Header>
    <a:Action s:mustUnderstand="1">http://tempuri.org/IService1/GetData</a:Action>
    <a:MessageID>urn:uuid:f3c2172e-eeb9-4dfd-8e1b-3a623088b78f</a:MessageID>
    <a:ReplyTo>
      <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
    </a:ReplyTo>
  </s:Header>
  <s:Body>
    <GetData xmlns="http://tempuri.org/">
      <value>0</value>
      <value2>test</value2>
    </GetData>
  </s:Body>
</s:Envelope>

我在这里错过了什么？例外中没有进一步的细节。
