Razor, ASP.Net, user authentication

Question

I am wondering why the following:

             @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>
             @}

Is throwing the following error:

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

This error is thrown on my else if block. I am new to ASP.net and razor, but from my understanding what I did is correct no? Since they both are Boolean returns.

I think you don't need the "@" in the else if.

Try like this:

        @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>
        }

Your razor syntax is goofed. You should surround the entire if/else if block with the @{} and remove the @ symbol from the various closing braces in your if/else branch.

@{
    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>
    }
}

Or just use @if. Since the HTML tags within each block are valid, Razor can figure out that the else if and closing bracket are code.

@JasonBerkan - good point. I think that these two methods are just style choices at that point.
