有沒有更好的方式來顯示與角色的HTML代碼比如果MVC剃刀意見

報表

目前我在C＃我的會員角色代碼結構像下面這樣

@if (WebApiApplication.CurrentUser.CurrentRole == Role.SysAdmin || WebApiApplication.CurrentUser.CurrentRole == Role.Coordinator) 
{ 
    <li id="HomeMenu" class="@Model.GetMenuClass("HomeMenu")"><a href="@Url.Action("Index", "Home")"><i class="fa fa-home"></i>&nbsp;&nbsp;Home</a></li> 
    <li id="InternsMenu" class="@Model.GetMenuClass("InternsMenu")"><a href="@Url.Action("Index", "Interns")"><i class="fa fa-user"></i>&nbsp;&nbsp;Interns</a></li> 
    <li id="ProjectsMenu" class="@Model.GetMenuClass("ProjectsMenu")"><a href="@Url.Action("Index", "Projects")"><i class="fa fa-list-alt"></i>&nbsp;&nbsp;Projects</a></li> 
    <li id="AssignmentsMenu" class="@Model.GetMenuClass("AssignmentsMenu")"><a href="@Url.Action("Index", "Assignments")"><i class="fa fa-paperclip"></i>&nbsp;&nbsp;Assignments</a></li> 
} 
@if (WebApiApplication.CurrentUser.CurrentRole == Role.User) 
{ 
    <li id="HomeMenu" class="@Model.GetMenuClass("HomeMenu")"><a href="@Url.Action("Index", "Home")"><i class="fa fa-home"></i>&nbsp;&nbsp;Home</a></li> 
    <li id="InternsMenu" class="@Model.GetMenuClass("InternsMenu")"><a href="@Url.Action("Index", "Interns")"><i class="fa fa-user"></i>&nbsp;&nbsp;Interns</a></li> 
    <li id="ProjectsMenu" class="@Model.GetMenuClass("ProjectsMenu")"><a href="@Url.Action("Index", "Projects")"><i class="fa fa-list-alt"></i>&nbsp;&nbsp;Projects</a></li> 
    <li id="AssignmentsMenu" class="@Model.GetMenuClass("AssignmentsMenu")"><a href="@Url.Action("Index", "Assignments")"><i class="fa fa-paperclip"></i>&nbsp;&nbsp;Assignments</a></li> 
} 

@if (WebApiApplication.CurrentUser.CurrentRole == Role.Intern) 
{ 
    <li id="HomeMenu" class="@Model.GetMenuClass("HomeMenu")"><a href="@Url.Action("Index", "Home")"><i class="fa fa-home"></i>&nbsp;&nbsp;Home</a></li> 
    <li id="TimecardMenu" class="@Model.GetMenuClass("TimecardMenu")"><a href="@Url.Action("Timecard", "Assigments")"><i class="fa fa-user"></i>&nbsp;&nbsp;Interns</a></li> 
    <li id="FeedbackMenu" class="@Model.GetMenuClass("ProjectsMenu")"><a href="@Url.Action("Feedback", "Assigments")"><i class="fa fa-list-alt"></i>&nbsp;&nbsp;Projects</a></li> 
    <li id="SupportMenu" class="@Model.GetMenuClass("SupportMenu")"><a href="@Url.Action("Index", "Support")"><i class="fa fa-question-circle"></i>&nbsp;&nbsp;Support</a></li> 
} 

做這將是多麼美好處理方式角色邏輯代替剃刀查看？在C＃模型中做它？

我認爲這樣的事情可以在視圖中處理，因爲它處理頁面中菜單項的顯示。

正如其他人在評論中提到的那樣，最好在視圖模型中定義映射到用戶角色並使用它的屬性。

您可以改用switch語句，並將適用於不同角色的選項分組。例如，我在您的示例中注意到，角色SysAdmin，協調員和用戶都具有相同的菜單項，所有角色都可以訪問主菜單，並且只有角色實習生可以看到TimeCard，反饋和支持菜單。

見下面的例子：

<li id="HomeMenu" class="@Model.GetMenuClass("HomeMenu")"><a href="@Url.Action("Index", "Home")"><i class="fa fa-home"></i>&nbsp;&nbsp;Home</a></li> 

    @switch (WebApiApplication.CurrentUser.CurrentRole) 
     { 
      case Role.SysAdmin: 
      case Role.Coordinator: 
      case Role.User: 
      <li id="InternsMenu" class="@Model.GetMenuClass("InternsMenu")"><a href="@Url.Action("Index", "Interns")"><i class="fa fa-user"></i>&nbsp;&nbsp;Interns</a></li> 
      <li id="ProjectsMenu" class="@Model.GetMenuClass("ProjectsMenu")"><a href="@Url.Action("Index", "Projects")"><i class="fa fa-list-alt"></i>&nbsp;&nbsp;Projects</a></li> 
      <li id="AssignmentsMenu" class="@Model.GetMenuClass("AssignmentsMenu")"><a href="@Url.Action("Index", "Assignments")"><i class="fa fa-paperclip"></i>&nbsp;&nbsp;Assignments</a></li> 
      break; 
      case Role.Intern: 
      <li id="TimecardMenu" class="@Model.GetMenuClass("TimecardMenu")"><a href="@Url.Action("Timecard", "Assigments")"><i class="fa fa-user"></i>&nbsp;&nbsp;Interns</a></li> 
      <li id="FeedbackMenu" class="@Model.GetMenuClass("ProjectsMenu")"><a href="@Url.Action("Feedback", "Assigments")"><i class="fa fa-list-alt"></i>&nbsp;&nbsp;Projects</a></li> 
      <li id="SupportMenu" class="@Model.GetMenuClass("SupportMenu")"><a href="@Url.Action("Index", "Support")"><i class="fa fa-question-circle"></i>&nbsp;&nbsp;Support</a></li> 
      break; 
     }
