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!

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();
}
