How to add HTTP Header to SOAP Client

Question

Can someone answer me if it is possible to add HTTP header to soap client web-service calls. After surfing Internet the only thin I found was how to add SOAP header.

Answer 1

Try to use this:

SoapServiceClient client = new SoapServiceClient();

using(new OperationContextScope(client.InnerChannel)) 
{
    // // Add a SOAP Header (Header property in the envelope) to an outgoing request. 
    // MessageHeader aMessageHeader = MessageHeader
    //    .CreateHeader("MySOAPHeader", "http://tempuri.org", "MySOAPHeaderValue");
    // OperationContext.Current.OutgoingMessageHeaders.Add(aMessageHeader);

    // Add a HTTP Header to an outgoing request
    HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();
    requestMessage.Headers["MyHttpHeader"] = "MyHttpHeaderValue";
    OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] 
       = requestMessage;

    var result = client.MyClientMethod();
}

See here for more detail.

Answer 2

Try this

var client = new MyServiceSoapClient();
using (var scope = new OperationContextScope(client.InnerChannel))
{
    // Create a custom soap header
    var msgHeader = MessageHeader.CreateHeader("myCustomHeader", "The_namespace_URI_of_the_header_XML_element", "myValue");
    // Add the header into request message
    OperationContext.Current.OutgoingMessageHeaders.Add(msgHeader);

    var res = await client.MyMethod();
}

Answer 3

var client = new MyServiceSoapClient();
using (new OperationContextScope(InnerChannel))
{ 
    WebOperationContext.Current.OutgoingRequest.Headers.Add("myCustomHeader", "myValue");                
}
