Razor 语法缺少 } 字符

我认为这是一个男生错误，但你能否向我解释一下并提供此视图不起作用的修复方法：

@{
    int PreviousOrderId = 0;
}


@foreach (var item in Model) {

<div class="orderdetail">


@if (item.ID != PreviousOrderId){

    <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><div style="width:140px; overflow:auto;">@item.Licence.LicenceKey</div></span>
        <span class="strong">Serial No:<span><span>@item.Licence.SerialNumber</span>
    </div>               

    <div class="clear></div>
</div>
@{
   PreviousOrderId = item.ID;
}

}

span 标签附近缺少 / ，clear-div 标签中的类属性附近缺少 " ，并且 PreviousOrderId = item.ID 周围的 @{ } 不是必需的

@{
    int PreviousOrderId = 0;
}


@foreach (var item in Model) {

<div class="orderdetail">


@if (item.ID != PreviousOrderId){

    <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><div style="width:140px; overflow:auto;">@item.Licence.LicenceKey</div></span>
        <span class="strong">Serial No:</span><span>@item.Licence.SerialNumber</span>
    </div>               

    <div class="clear"></div>
</div>

   PreviousOrderId = item.ID;


}
