邮递员中的Soap请求

我有一个PHP Soap请求,我正试图将它转移到C#。我以前从未使用过Soap,我对它的请求/响应结构感到非常困惑。

在我开始编码之前,我试着在邮递员那里测试一下。

以下是我的邮递员设置:

URL=http://example.com/service1.svc?singleWsdl
contentType=text/xml

下面是正在使用的PHP代码,工作正常:

$client = new SoapClient($wsdlurl, $options);
$customerData = $client->NewCustAddDC($params);

这里是 $params 是一个如下所示的数组:

<NewCustomerAdd>
  <InitParameters>
    <InitOrderLines>
      <InitPartDesc />
      <InitPartSKU>test</InitPartSKU>
      <InitQuantity>1</InitQuantity>

请求正文 :

我到底做错了什么?
