C# 非静态字段、方法或属性需要对象引用 'HttpContext.Request'

Question

我正在尝试创建一个通用工厂类来调用 WCF 并注入(inject)一些 header 。在这个类中，我试图阅读 HTTP Header 属性。

    using System.ServiceModel;
    using System.ServiceModel.Channels;
    using ServiceReference;
    using Microsoft.AspNetCore.Http;
namespace Service
{
     public class ServiceFactory
        {

            public static ServiceClient Create()
            {
                ServiceProxy service = new ServiceProxy();
                string userName = HttpContext.Request.Headers["AUTH_USERNAME"];
                string authenricationType = HttpContext.Request.Headers["AUTH_TYPE"];

                using (new System.ServiceModel.OperationContextScope((System.ServiceModel.IClientChannel)service.InnerChannel))
                {          
                    HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();
                    requestMessage.Headers["AUTH_USERNAME"] = userName;
                    OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;

                    requestMessage.Headers["AUTH_TYPE"] = authenricationType;
                    OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;
                }
                return service;
            }       
        }
}

但我得到一个编译错误 “非静态字段、方法或属性'HttpContext.Request'需要对象引用。因为我不是从静态方法调用或一个类如何发生这种情况。任何帮助将不胜感激。

谢谢。

HttpContext.Request 不起作用，因为它试图像访问静态属性一样访问实例属性。 HttpContext.Current.Request 应该可以工作，假设此时上下文已经与线程相关联
