c# - 如何知道是什么导致我的操作遇到多个线程？

问题描述

我有一个包含近 5 个字段的简单表单提交，在提交时它运行到 4 个线程，因此在单个 post 方法调用中将 4 个条目保存在表中。我附上了一张图片和代码，说明我面临的问题的相关性。

我的控制器：

public ActionResult Test(CustomerOrderVM CustomerOrderVM)
{
    try
    {
        if (CustomerOrderVM.Email == "")
        {
            ModelState.AddModelError("Email", "Please enter valid Country");
        }

        if (CustomerOrderVM.City == "" || CustomerOrderVM.City == "< Select City >")
        {
            ModelState.AddModelError("City", "Please enter valid City");
        }

        if (CustomerOrderVM.Contact == "")
        {
            ModelState.AddModelError("Contact", "Please enter valid Contact Number");
        }

        if (CustomerOrderVM.FullName == "")
        {
            ModelState.AddModelError("FullName", "Please enter valid FullName");
        }

        if (ModelState.IsValid)
        {
            tblCustomerOrder _tblCustomerOrder = new tblCustomerOrder();

            _tblCustomerOrder.FullName = CustomerOrderVM.FullName;
            _tblCustomerOrder.Address = CustomerOrderVM.Address;
            _tblCustomerOrder.City = CustomerOrderVM.City;
            _tblCustomerOrder.Contact = CustomerOrderVM.Contact;
            _tblCustomerOrder.Email = CustomerOrderVM.Email;
            _tblCustomerOrder.Proceeded = false;

            db.tblCustomerOrders.Add(_tblCustomerOrder);

            db.SaveChanges();

            return Json(CustomerOrderVM);
        }
        else
        {
            return Json("");
        }
    }
    catch (Exception)
    {
        ViewBag.Error = "Error";
        return Json(ViewBag.Error);
    }
}

我的视图模型：

public class CustomerOrderVM
{
    public int Id { get; set; }

    [Required]
    [RegularExpression(@"^[a-zA-Z\s]+$", ErrorMessage = "Please enter valid name")]
    [Display(Name = " Name")]
    [StringLength(200, ErrorMessage = "Please enter valid name", MinimumLength = 3)]
    public string FullName { get; set; }

    [DataType(DataType.EmailAddress)]
    [StringLength(150, ErrorMessage = "Please enter valid Email Id", MinimumLength = 5)]
    [Display(Name = "Email ID")]
    public string Email { get; set; }

    [Required]
    [RegularExpression("^[0-9]*$", ErrorMessage = "Please enter valid  Mobile No")]
    [StringLength(15, ErrorMessage = "Please enter valid Mobile No", MinimumLength = 9)]
    [Display(Name = "Mobile No")]
    public string Contact { get; set; }

    [Required]
    [Display(Name = "Street Address")]
    [StringLength(200, ErrorMessage = "Please enter valid address", MinimumLength = 7)]
    [DataType(DataType.MultilineText)]
    public string Address { get; set; }

    [Required]
    [Display(Name = "City")]
    public string City { get; set; }

    [Display(Name = "Proceeded")]
    public bool? Proceeded { get; set; }
}

这是一个问题，有 4 个线程正在运行，由黄色荧光笔指出，附在下面
