剃鬚刀，ASP.Net，用戶認證

Question

我很奇怪，爲什麼以下內容：

   @if(Request.LogonUserIdentity.IsAnonymous){ 
       <ul id="menu"> 
        <li>@Html.ActionLink("Location", "Index", "Location")</li> 
        <li>@Html.ActionLink("Map", "Map", "Home")</li> 
        <li>@Html.ActionLink("Help", "Help", "Home")</li> 
       </ul> 
      @}else if(Request.LogonUserIdentity.IsAuthenticated){ 
       <ul id="menu"> 
        <li>@Html.ActionLink("Location", "Index", "Location")</li> 
        <li>@Html.ActionLink("Service", "Index", "Service")</li> 
        <li>@Html.ActionLink("Service Assignment", "Index", "ServiceAssignment")</li> 
        <li>@Html.ActionLink("Content Management", "Index", "Content")</li> 
       </ul> 
      @} 

拋出以下錯誤：

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1501: No overload for method 'Write' takes 0 arguments

這個錯誤是我else if塊拋出。我是ASP.net和剃鬚刀的新手，但是從我的理解來看，我所做的是正確的？因爲它們都是布爾返回。

Answer 1

我認爲你不需要在其他的「@」如果。

嘗試這樣的：

 @if(Request.LogonUserIdentity.IsAnonymous){ 
      <ul id="menu"> 
       <li>@Html.ActionLink("Location", "Index", "Location")</li> 
       <li>@Html.ActionLink("Map", "Map", "Home")</li> 
       <li>@Html.ActionLink("Help", "Help", "Home")</li> 
      </ul> 
     }else if(Request.LogonUserIdentity.IsAuthenticated){ 
      <ul id="menu"> 
       <li>@Html.ActionLink("Location", "Index", "Location")</li> 
       <li>@Html.ActionLink("Service", "Index", "Service")</li> 
       <li>@Html.ActionLink("Service Assignment", "Index", "ServiceAssignment")</li> 
       <li>@Html.ActionLink("Content Management", "Index", "Content")</li> 
      </ul> 
     }

您的剃鬚刀語法是愚蠢的。您應該將整個if/else if塊與@{}環繞，並從if/else分支中的各個右花括號中刪除@符號。

@{ 
    if (Request.LogonUserIdentity.IsAnonymous) 
    { 
     <ul id="menu"> 
      <li>@Html.ActionLink("Location", "Index", "Location")</li> 
      <li>@Html.ActionLink("Map", "Map", "Home")</li> 
      <li>@Html.ActionLink("Help", "Help", "Home")</li> 
     </ul> 
    } 
    else if (Request.LogonUserIdentity.IsAuthenticated) 
    { 
     <ul id="menu"> 
      <li>@Html.ActionLink("Location", "Index", "Location")</li> 
      <li>@Html.ActionLink("Service", "Index", "Service")</li> 
      <li>@Html.ActionLink("Service Assignment", "Index", "ServiceAssignment")</li> 
      <li>@Html.ActionLink("Content Management", "Index", "Content")</li> 
     </ul> 
    } 
}
