Question

今天我正在玩Razor！你能看出这个观点有什么问题并解释它为什么会出错吗？

@foreach (var item in Model){

if (item.ID != PreviousOrderId){
    <div class="orderdetail">
        <div class="customer">
            <p class="strong">OrderID:</p> 
            <p>@item.ID</p>
            <p class="strong">Order Date:</p>
            <p>@String.Format("{0:g}", TimeZoneInfo.ConvertTime(item.DateInitialised, TimeZoneInfo.FindSystemTimeZoneById("GMT Standard Time")))</p>
            <p class="strong">Customer Name:</p> 
            <p>@item.WebsiteUser.Name</p>
            <p class="strong">Practice Name:</p>
            <p>@item.WebsiteUser.PracticeName</p>
            <p class="strong">Customer E-Mail:</p> 
            <p>@item.WebsiteUser.EMailAddress</p>
        </div>
   }



    <div class="detail">
        <span class="strong">Licence Key:</span><span>@item.Licence.LicenceKey</span>
        <span class="strong">Serial No:</span><span>@item.Licence.SerialNumber</span>
    </div>               

   @if (item.ID != PreviousOrderId && PreviousOrderId != 0){
    </div>
    <div class="clear"></div>
   }        

PreviousOrderId = item.ID;
}

Answer 1

您已将<div class="orderdetail">分为两部分。开始标记位于第一个if块中，结束标记位于第二个if块中。

这让Razor感到困惑，我想。

尝试在一个div区块中打开和关闭if。

Answer 2

如果您已经在代码块中，则不再需要@ -prefix代码构造......您的代码块以@foreach开头。

@foreach (var x in new string[] { "x", "y" ])
{
    if (userGuid != ViewBag.x)
   {
    @:<div class="orderdetail">
    <div class="customer">
        <p class="strong">OrderID:</p> 
        <p>@item.ID</p>
        <p class="strong">Order Date:</p>
        <p>@String.Format("{0:g}", TimeZoneInfo.ConvertTime(item.DateInitialised</p>
        <p class="strong">Customer Name:</p> 
        <p>@item.WebsiteUser.Name</p>
        <p class="strong">Practice Name:</p>
        <p>@item.WebsiteUser.PracticeName</p>
        <p class="strong">Customer E-Mail:</p> 
        <p>@item.WebsiteUser.EMailAddress</p>
    </div>
    }
    <div class="detail">
        <span class="strong">Licence Key:</span><span>@item.Licence.LicenceKey</span>
        <span class="strong">Serial No:</span><span>@item.Licence.SerialNumber</span>
    </div>               

if (userGuid != ViewBag.x && ViewBag.x != 0)
{
    @:</div>
    <div class="clear"></div>
}      
PreviousOrderId = item.ID;    
}

foreach块缺少一个结束“}”字符
