我有一个Winform应用程序，我可以使用TCP客户端连接到WCF服务，但我不知道如何调用它的功能。
我一直在考虑通过TCP客户端向WCF服务发送SOAP-XML请求，但总是得到＆＃34;错误请求＆＃34;响应。
这是我的要求：
POST /MyService.svc HTTP/1.1
Host: MyHost.com
Content-Type: text/xml; charset=utf-8
Content-Length: 700
SOAPAction: "http://MyHost.com/MyService/MyFunction"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance
xmlns:xsd=http://www.w3.org/2001/XMLSchema
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<Action soap:must Understand="1"
xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">
http://MyHost.com/MyService/MyFunction
</Action>
</soap:Header>
<soap:Body>
<MyFunction xmlns="http://MyHost.com/">
</MyFunction>
</soap:Body>
以下是回复：
