} 预期的部分视图剃刀错误

Question

我在 Umbraco 部分视图中有如下代码。即使 { } 对匹配，它也会显示错误，即预期的 }。

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@{  
var langstr = "All";
var pageSize = 6;
var max_pages=0;
try
{
    if (@ViewData["storylang"] == null)
    {
        langstr = "";
    }
    else
    {
        langstr = @ViewData["storylang"].ToString();
    }
}
catch (Exception ex)
{
    langstr = "";
}

var pageIndex = (int)@ViewData["page_index"]; 
dynamic selected;

if (@ViewData["curpage"] != null)
{

    var id = (int)@ViewData["curpage"];
    var currentNode = Umbraco.TypedContent(id);
    selected = currentNode.Children.Where("Visible");


   if(langstr != ""){
        selected = currentNode.Children.Where("Visible").Where("language=\"" + @langstr + "\"");
        max_pages = currentNode.Children.Count();

        <ul>
            @foreach (var story in selected.Take(pageIndex * pageSize))
            {

               <li class="col-lg-3 col-md-3 col-sm-6 col-xs-12"><a href="@story.Url" class="\""st-text"\">@story.Name</a></li>
            }
        </ul>

    }

}
else
{
    selected = CurrentPage.Children.Where("Visible");
    max_pages = CurrentPage.Children.Count();
    if(selected.Any()){
        <ul>
            @foreach (var story1 in selected.Take(pageIndex * pageSize))
            {
                <li class="col-lg-3 col-md-3 col-sm-6 col-xs-12"><a href="@story1.Url" class="st-text">@story1.Name</a></li>
            }
        </ul>

    }
}


}

代码有什么问题？任何人都可以解决同样的问题吗？我哪里错了？这背后我付出了很多。

Answer 1

还要比较主视图的所有左括号和右括号。

   @inherits Umbraco.Web.Mvc.UmbracoTemplatePage
   @{
    var langstr = "All";
    var pageSize = 6;
    var max_pages=0;
    try
    {
        if (ViewData["storylang"] == null)
        {
            langstr = "";
        }
        else
        {
            langstr = ViewData["storylang"].ToString();
        }
    }
    catch (Exception ex)
    {
        langstr = "";
    }

    var pageIndex = (int)ViewData["page_index"];
    dynamic selected;

    if (ViewData["curpage"] != null)
    {

        var id = (int)ViewData["curpage"];
        var currentNode = Umbraco.TypedContent(id);
        selected = currentNode.Children.Where("Visible");


        if(langstr != "")
        {
            selected = currentNode.Children.Where("Visible").Where("language=\"" + @langstr + "\"");
            max_pages = currentNode.Children.Count();

            <ul>
            @foreach (var story in selected.Take(pageIndex * pageSize))
            {
                <li class="col-lg-3 col-md-3 col-sm-6 col-xs-12"><a href="@story.Url" class="st-text">@story.Name</a></li>
            }
            </ul>

        }

    }
    else
    {
        selected = CurrentPage.Children.Where("Visible");
        max_pages = CurrentPage.Children.Count();
        if(selected.Any()){
        <ul>
        @foreach (var story1 in selected.Take(pageIndex * pageSize))
        {
        <li class="col-lg-3 col-md-3 col-sm-6 col-xs-12"><a href="@story1.Url" **class="st-text"**>@story1.Name</a></li>
        }
        </ul>

    }
}
}

Answer 2

你有两个问题。

首先，这个：

class="\""st-text"\"

阻止正确解析该行并弄乱以下内容。你可能是说

class="st-text"

或

class='"st-text"'

然后，所有已经在 C# 代码上下文中的 @ViewData 必须替换为 ViewData（即全部）。

Answer 3

我解决了这个问题。它正在混合代码和渲染块...... 所以这是解决方案。

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@{  
var langstr = "All";
var pageSize = 6;
var max_pages=0;
try
{
    if (ViewData["storylang"] == null)
    {
        langstr = "";
    }
    else
    {
        langstr = ViewData["storylang"].ToString();
    }
}
catch (Exception ex)
{
    langstr = "";
}

var pageIndex=1;
if(ViewData["page_index"]!=null)
{
pageIndex=   (int)@ViewData["page_index"]; 
}
dynamic selected;
}

@if (ViewData["curpage"] != null){

var id = (int)ViewData["curpage"];
var currentNode = Umbraco.TypedContent(id);
selected = currentNode.Children.Where("Visible");


if(langstr != ""){
    selected = currentNode.Children.Where("Visible").Where("language=\"" + @langstr + "\"");
    max_pages = currentNode.Children.Count();
    <ul>
        @foreach (var story in selected.Take(pageIndex * pageSize))
        {

            <li class="col-lg-3 col-md-3 col-sm-6 col-xs-12"><a href="@story.Url" class="st-text">@story.Name</a></li>
        }
    </ul>

}
 else{
    selected = currentNode.Children.Where("Visible");
    max_pages = currentNode.Children.Count();
    <ul>
        @foreach (var story in currentNode.Children.Where("Visible").Take(pageIndex * pageSize))
        {

            <li class="col-lg-3 col-md-3 col-sm-6 col-xs-12"><a href="@story.Url" class="st-text">@story.Name</a></li>
        }
    </ul>
}
}
 else
{
selected = CurrentPage.Children.Where("Visible");
max_pages = CurrentPage.Children.Count();
if (selected.Any())
{
        <ul>
            @foreach (var story in selected.Take(pageIndex * pageSize))
            {
                <li class="col-lg-3 col-md-3 col-sm-6 col-xs-12"><a href="@story.Url" class="st-text">@story.Name</a></li>
            }
        </ul>

}
}
