C＃-无法识别右括号 [英] C# - Closing brackets aren't being recognized

问题描述

我有一个类似这样的控制器方法

I have a controller method that looks like this

    public ActionResult SpecialOrderSummary(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }

            JobOrder jobOrder = db.JobOrders.Find(id);
            if (jobOrder == null)
            {
                return HttpNotFound();
            }
            ViewBag.JobOrderID = jobOrder.ID;
            ItemInstance ii = db.ItemInstances.Where(x => x.serialNumber == jobOrder.serialNumber).FirstOrDefault();
            Item item = db.Items.Find(ii.ItemID);

            var vm = new ItemViewModel
            {
                ItemId = item.ItemID,
                ItemName = item.Name,
                Parts = new List<ItemPartViewModel>
                {
                  foreach (ItemHasParts ihp in item.IHP) 
                  {
                      Part part = db.Parts.Find(ihp.PartID);
                      new ItemPartViewModel
                      {
                         PartId = part.ID,
                         PartName = part.Name
                      };
                  }
                } //this is closing method
            }; // this is closing controller
            
            return View(vm);
        }

但零件的结尾} 列表和虚拟机不在右括号内。取而代之的是，部件} 关闭方法，而vm } 关闭控制器。

But the closing } to the Parts list and the vm aren't closing the right brackets. Instead, the Parts } is closing the method while the vm } is closing the controller.

为什么会这样？我的语法有问题吗？

Why is this happening? Is there an issue with my syntax?

推荐答案

是的，您不能拥有 foreach 零件列表初始化内的c $ c>循环。

Yea you can't have a foreach loop inside the Parts list initialization.

您必须执行以下操作：

var vm = new ItemViewModel
{
    ItemId = item.ItemID,
    ItemName = item.Name,
    Parts = new List<ItemPartViewModel>()
};

foreach (ItemHasParts ihp in item.IHP) 
{
    Part part = db.Parts.Find(ihp.PartID);

    vm.Parts.Add(new ItemPartViewModel
    {
        PartId = part.ID,
        PartName = part.Name
    };
}

我很惊讶编译器实际上允许您进行编译？

I am surprised the compiler actually let you compile?
