我整理了你的代码：

 @ model List <   habg.models.otherservices  >  

 @using（Html.BeginUmbracoForm <   habg.pocos.otherservicessurfacecontroller  > （otherservices）） 
 {
 @ Html.AntiForgeryToken（）
 if（Model！= null）
 {
 if（Model.Count> 0）
 {
 int j = 0; 
 foreach（var.in Model.FindAll（i => i.TourType == 1）.ToList（））
 {
 if（j == 0）
 { 
<   h4  > 有组织的旅游<   / h4  >  
<   ul     class   =  os_list >  
<   li  >  
 @ Html.HiddenFor（a => a [j] .TourServiceId）
 @ Html.HiddenFor（a => a [j] .BookingId）
<   div     class   =  imgHolder >  <   img     src   =   @ System.Web.Configuration.WebConfigurationManager.AppSettings [    adminproductimage_virtualpath   = ] @ i.ImagePath    /  >   <   / div  >  <！ -     imgHolder    - >   
<   div     class   =  imgInfo &gt ;  
 @ i.TourService_Title 
<   p  >  @ i.TourService_Description <   / p  >  
价格：@ i.Price 
<   / div  >  <！ -     imgInfo    - >   
<   div     class   =  os_form >  
 @ i.StartDate to @ i.EndDate 
<   span  >  <   label  > 否。人<   / label  >  @ Html.TextBoxFor（a => a [j] .PersonCnt，new {@class =personNo topInsideShadow numericOnly，@ maxlength =2}）<   / span  >  
<   span  >  <  标签 > 检查以获取<   / label  >  @ Html.CheckBoxFor（a => a [j] .IsSelected）<   / span  >  
<   / div  >  <！ -     os-form    - &gt ;   
<   / li  >  
j = j + 1; 

<   / ul   >  
} 
<  输入   类型  = 提交    value   = 提交    class   =  submitBtn    /  >  
} 
} 
} 
} <   / habg.pocos.others ervicessurfacecontroller  >  <   / habg。 models.otherservices  >  

你有太多的括号和太多的@符号

@model List<habg.Models.OtherServices>

@using (Html.BeginUmbracoForm<habg.pocos.OtherservicesSurfaceController>("otherservices"))
{
    @Html.AntiForgeryToken()
    if (Model!= null)
    {
        
        @if (Model != null && Model.Count > 0) 
        {
            int j=0;
            foreach(var i in Model.FindAll(i=>i.TourType == 1).ToList())
            {
                if(j==0)
                {
                    <h4>Organised Tour</h4>
                    <ul class="os_list">
                }
                <li>
                    @Html.HiddenFor(a => a[j].TourServiceId)
                    @Html.HiddenFor(a=>a[j].BookingId)
                    <div class="imgHolder"><img src="@System.Web.Configuration.WebConfigurationManager.AppSettings["AdminProductImage_VirtualPath"]@i.ImagePath" /></div><!--imgHolder-->
                    <div class="imgInfo">
                        @i.TourService_Title
                        <p>@i.TourService_Description</p>
                        Price : @i.Price
                    </div><!--imgInfo-->
                    <div class="os_form">
                        @i.StartDate to @i.EndDate
                        <span><label>No. of person</label>@Html.TextBoxFor(a => a[j].PersonCnt, new { @class = "personNo topInsideShadow numericOnly", @maxlength="2" })</span>
                        <span><label>Check to avail</label>@Html.CheckBoxFor(a=> a[j].IsSelected)</span>
                    </div><!--os-form-->
                </li>
                j = j + 1;
            }
         }
        </ul>
    <input type="submit" value="submit" class="submitBtn" />
    }
    
}

The error I am getting -
The using 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.

I tidied up your code:

@model List<habg.models.otherservices>

@using (Html.BeginUmbracoForm<habg.pocos.otherservicessurfacecontroller>("otherservices"))
{
    @Html.AntiForgeryToken()
    if (Model!= null)
    {
        if (Model.Count > 0)
        {
            int j=0;
            foreach(var i in Model.FindAll(i=>i.TourType == 1).ToList())
            {
                if(j==0)
                {
                    <h4>Organised Tour</h4>
                    <ul class="os_list">

                        j = j + 1;

                    </ul>
                }
                    <input type="submit" value="submit" class="submitBtn" />

You had too many brackets and too many "@" symbols.
