C# 向请求添加消息头

正在尝试在c中将此标头添加到我的请求中：

<soap:Header>
<UserCredentials soap:mustUnderstand="1" xmlns="http://test.credential.com/UserCredentials" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<CicsUsername xmlns="http://schemas.test.org/2004/07/test.Mainframe">ciscs</CicsUsername>
<TechnicalPassword "http://schemas.test.org/2004/07/test.Mainframe">password</TechnicalPassword>
<TechnicalUsername "http://schemas.test.org/2004/07/test.Mainframe">user</TechnicalUsername>
</UserCredentials>
</soap:Header>   

我尝试过，但没有成功：

问候

伙计，正如前面的链接所示，我们可以使用OperationContext添加自定义消息头。请参考下面的例子，希望对你有用。 服务器控制台应用程序，10.157.13.69:3336

服务器端的Appconfig

ClientConsole应用程序，使用ChannelFactory调用

结果。 此外，我们还可以使用IClientMessageInspector接口创建一个持久的SOAP消息头，因为上面的操作表明添加SOAP消息头只在USING语句中有效。请参阅我先前的答复。 如果有什么我能帮忙的，请随时告诉我
