C＃多个属性调用序列

Question

我有多个属性我想应用在控制器上，我需要按顺序调用它们，因为如果第一个属性执行，我初始化下列属性将使用的变量。我的属性

[AuthorizeLicense] 
[MerchantLoggedIn] 
[MerchantAuthorize] 
public class MerchantController : BaseController 
{ 
} 

定义

public class AuthorizeLicense:AuthorizeAttribute 
{ 
    protected override bool AuthorizeCore(HttpContextBase httpContext) 
    { 

     if(somecondition is true){ 
    //initialize variables for next attribute use; 
     } 

    } 

    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext) 
    { 


    } 


} 

下一个属性

public class MerchantLoggedIn:AuthorizeAttribute 
{ 
    protected override bool AuthorizeCore(HttpContextBase httpContext) 
    { 

      //use initialize variables from previous attribute 


    } 

    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext) 
    { 


    } 


} 

我面临的挑战是，属性不是序列中被称为我已经在类中定义它们;即从上到下。 请帮忙..我做错了什么。

可以使用秩序参数

[AuthorizeLicense(Order = 1)] 
[MerchantLoggedIn(Order = 2)] 
public class ...
