如何创建soap信封以在c＃.net中向Web服务发送请求

Question

我必须向Web服务发送SOAP请求。客户端为我提供了WSDL，端点，x509证书以及WSDL链接。我必须创建以下请求，但我无法帮助我。

我创建了WCF客户端并添加了它创建的app.config的WSDL引用。

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <bindings>
      <customBinding>
        <binding name="PreAuthBinding12">
          <textMessageEncoding maxReadPoolSize="64" 
                               maxWritePoolSize="16"
                               messageVersion="Soap12" 
                               writeEncoding="utf-8">
            <readerQuotas maxDepth="32" 
                          maxStringContentLength="8192" 
                          maxArrayLength="16384"
                          maxBytesPerRead="4096" 
                          maxNameTableCharCount="16384" />
          </textMessageEncoding>
          <httpsTransport manualAddressing="false" 
                          maxBufferPoolSize="524288"
                          maxReceivedMessageSize="65536" 
                          allowCookies="false" 
                          authenticationScheme="Anonymous"
                          bypassProxyOnLocal="false"
                          hostNameComparisonMode="StrongWildcard"
                          keepAliveEnabled="true" 
                          maxBufferSize="65536" 
                          proxyAuthenticationScheme="Anonymous"
                          realm="" transferMode="Buffered"
                          unsafeConnectionNtlmAuthentication="false"
                          useDefaultWebProxy="true" requireClientCertificate="false" />
        </binding>
      </customBinding>
    </bindings>
    <client>
      <endpoint address="https:ww.abc.com"
                binding="customBinding" 
                bindingConfiguration="PreAuthBinding12"
                contract="Vpay" name="PreAuthorizationServicePort12" />
    </client>
  </system.serviceModel>
</configuration>

所以我不明白如何使用x509证书创建soap信封，如何创建签名，摘要算法，规范，wsu，wsse。
