剃须刀，ASP.Net，用户认证

Question

我很奇怪，为什么以下内容：

   @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> 
      @} 

抛出以下错误：

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

这个错误是我else if块抛出。我是ASP.net和剃须刀的新手，但是从我的理解来看，我所做的是正确的？因为它们都是布尔返回。

我认为你不需要在其他的“@”如果。

尝试这样的：

 @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> 
     }

您的剃须刀语法是愚蠢的。您应该将整个if/else if块与@{}环绕，并从if/else分支中的各个右花括号中删除@符号。

@{ 
    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> 
    } 
}
