不包含构造函数参数 - 错误 [英] does not contain a constructor argument - error

问题描述

亲爱的，



我想知道如何为以下代码设置参数，因为它当前正在输出编译错误 - 'user_feb2014.BasicAuthHandler'不包含带0参数的构造函数 - 错误。



Global.aspx类

Dear all,

I would like to know how can setup argument for the following code, as it currently outputting an compiling error - 'user_feb2014.BasicAuthHandler' does not contain a constructor that takes 0 arguments - error.

Global.aspx class

GlobalConfiguration.Configuration.MessageHandlers.Add(new BasicAuthHandler());

我尝试添加用户参数，但输出的错误更多。如果有人可以请我提供一些指导，那将非常有帮助。

I have tried adding user parameters but it outputs even more error. If someone could please provide me with some guidance, that would be very helpful.

public class BasicAuthHandler : DelegatingHandler
    {

        private const string BasicAuthResponseHeader = "WWW-Authenticate";
        private const string BasicAuthResponseHeaderValue = "Basic";

        private readonly iUser repository;

        public BasicAuthHandler(iUser repository)
      {
         this.repository = repository;
      }

非常感谢

Many thanks

推荐答案

您的构造函数需要参数：要加载到类中的存储库变量的iUser类/接口实例。



如果你没有可用的（我怀疑你需要找到一个）然后你将不得不创建一个不带参数的构造函数 - 但是你的存储库将会做什么变量后来是任何人的猜测。它可能会在系统后期导致失败。

Your constructor expects a parameter: an iUser class / interface instance to load into the repository variable in your class.

If you don't have one available (and I suspect you need to find one) then you will have to create a constructor that takes no arguments - but what that will do with your repository variable later is anybodies guess. It' will probably cause a failure later in the system.
