Adding HTTP request header to WCF request

Question

I have a WCF service consume by both AJAX and C# application,
I need to send a parameter through the HTTP request header.

On my AJAX I have added the following and it works:

$.ajax({
    type: "POST",
    url: this.tenantAdminService,
    beforeSend: function (req, methodName)
    {
        req.setRequestHeader("AdminGUID", adminGuid);
    }

and on the WCF server side I do the following to Get the header:

string adminGUID = System.Web.HttpContext.Current.Request.Headers["AdminGUID"];

What is the C# equivalent? How can I send the http request header that will also be consume by my WCF server?

I need to add the parameter to HTTP request header and not to the message header,

Thanks!

Solution

The simplest way to this is using WebOperationContext at the following way:

Service1Client serviceClient = new Service1Client();
using (new System.ServiceModel.OperationContextScope((System.ServiceModel.IClientChannel)serviceClient.InnerChannel))
{
    System.ServiceModel.Web.WebOperationContext.Current.OutgoingRequest.Headers.Add("AdminGUID", "someGUID");
    serviceClient.GetData();
}

Can I do this in a neater way? so that I wont have to put URL? since I already have service reference that contains all methods

You add the web service directly to your project c#. VS will automatically generate classes for you to call your web service directly but it might not give the option to add a request header, when calling the web service.

Thanks this helps a lot. Looks promising.
