C＃多個屬性調用序列

Question

我有多個屬性我想應用在控制器上，我需要按順序調用它們，因爲如果第一個屬性執行，我初始化下列屬性將使用的變量。我的屬性

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

定義

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) 
    { 


    } 


} 

下一個屬性

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

      //use initialize variables from previous attribute 


    } 

    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext) 
    { 


    } 


} 

我面臨的挑戰是，屬性不是序列中被稱爲我已經在類中定義它們;即從上到下。 請幫忙..我做錯了什麼。

可以使用秩序參數

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