Razor in .cshtml file - adding additional 'if' statements gives error
提问by Chris Halcrow
I'm trying to add a couple of if statements to a razor page. The page I'm changing worked before the changes however when I add the blocks I've highlighted in the code sample below I get this error:
我正在尝试向剃刀页面添加几个 if 语句。我正在更改的页面在更改之前工作，但是当我添加在下面的代码示例中突出显示的块时，我收到此错误：
Error loading Razor Script ~/macroscripts/genericpage.cshtml The code block is missing a closing "}" character. Make sure you have a matching "}" character for all the "{" characters within this block, and that none of the "}" characters are being interpreted as markup.
加载 Razor 脚本时出错 ~/macroscripts/genericpage.cshtml 代码块缺少关闭的“}”字符。确保此块中的所有“{”字符都有一个匹配的“}”字符，并且没有任何“}”字符被解释为标记。
if (publishedRightHandPods.Any())
{
foreach(var rh in publishedRightHandPods)
{
if (rh.image.GetType() == typeof(DynamicXml))
{
if (rh.link.GetType() == typeof(DynamicXml))
{
var linkSupplied = !String.IsNullOrEmpty(rh.link.url) && !String.IsNullOrWhiteSpace(rh.link.url);
var titleSupplied = !String.IsNullOrEmpty(rh.title) && !String.IsNullOrWhiteSpace(rh.title);
@* *************** *@
@* I'M ADDING THIS *@
@* *************** *@
@{
if (linkSupplied) {
<a href="@(rh.link.url)">
}
}
@* ****************** *@
@* END OF ADDED BLOCK *@
@* ****************** *@
<div class="side-pod" style="background: url('@(rh.image.mediaItem.Image.umbracoFile)') no-repeat scroll 0 0 transparent; height: @(rh.image.mediaItem.Image.umbracoHeight)px">
@{
if (titleSupplied)
{
<h2 class="title" style="color: #@(rh.textColour);">@Html.Raw(rh.title.ToString())</h2>
}
}
@{
if (!String.IsNullOrEmpty(rh.linkText) && !String.IsNullOrWhiteSpace(rh.linkText) && !String.IsNullOrEmpty(rh.link.url) && !String.IsNullOrWhiteSpace(rh.link.url))
{
<a class="findoutmore-btn" href="@(rh.link.url)">@(rh.linkText)</a>
}
}
</div>
@* *************** *@
@* I'M ADDING THIS *@
@* *************** *@
@{
if (linkSupplied) {
</a>">
}
}
@* ****************** *@
@* END OF ADDED BLOCK *@
@* ****************** *@
}
}
}
I don't understand why the if statements inside the <div>are working however when I add the new (similar) statements outside the div I get the error.
我不明白为什么里面的 if 语句<div>正在工作，但是当我在 div 之外添加新的（类似的）语句时，我得到了错误。
****UPDATE****
****更新****
If I remove the @{} surrounding the if statements that I added, like this:
如果我删除我添加的 if 语句周围的 @{}，如下所示：
if (linkSupplied) {
<a href="@(rh.link.url)">
}
I see this on screen:

When you need to open a HTML tag inside ifstatement but you don't want to close it, I suggest you to use @Html.Raw():
当您需要在if语句中打开 HTML 标记但又不想关闭它时，建议您使用@Html.Raw()：
@if (linkSupplied) {
@Html.Raw(string.Format("<a href=\"{0}\">", rh.link.url))
}
@if (linkSupplied) {
@Html.Raw(string.Format("<a href=\"{0}\">", rh.link.url))
}
...then, when you close Atag...
...然后，当您关闭A标签时...
@if (linkSupplied) {
@Html.Raw("</a>")
}
@if (linkSupplied) {
@Html.Raw("</a>")
}

You have an extra apostrophe and greater then sign after the last closing tag in the second if statement:
在第二个 if 语句的最后一个结束标记之后，您有一个额外的撇号和更大的 then 符号：
@{
if (linkSupplied) {
</a>">
}
}

try using global @{} rather than using it in every section. The markup will work fine inside the razor syntax. In this way you can simplify your code.
尝试使用全局 @{} 而不是在每个部分都使用它。标记将在 razor 语法中正常工作。通过这种方式，您可以简化您的代码。
