Asp.net mvc 如何在ASP.NETMVC中保存访问者机器的数据库客户端IP地址？

我正在尝试获取客户端计算机的IP地址

Request.ServerVariables[“HTTP_X_FORWARDED_FOR”]工作正常

在页面加载时获取IP

public ActionResult AddCompany()
        {
            get_IP();
            return View();
        }

获取IP代码

public void get_IP()
        {
            string ipAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
            if (string.IsNullOrEmpty(ipAddress))
            {
                ipAddress = Request.ServerVariables["REMOTE_ADDR"];
            }
            ViewBag.IPAddress = ipAddress;
        }

但当用户注册时，表单得到的IP地址值也保存在数据库中

Cs.html文件

<div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main">
    <h1 class="page-header">Add Company</h1>

    @using (Html.BeginForm())
    {
        @Html.AntiForgeryToken()

        <div class="form-horizontal">
            @Html.ValidationSummary(true)
            @Html.HiddenFor(model => model.IPAddress)
            <div class="form-group">

            <div>

                <select id="city"></select><br />
            </div>

            <div class="form-group">
                <div class="col-md-offset-2 col-md-10">
                    <input type="submit" value="Create" class="btn btn-default" />

        </div>
    }

    <div>
        @Html.ActionLink("Back to List", "Index")
    </div>
</div>

知道如何从数据库中保存客户端IP地址吗

类文件

[Table("MySecondMVCDemo")]
    public class Company
    {
        [Key]
        public int CompanyID { get; set; }
        [Required(ErrorMessage = "Please Enter Company Name")]
        [Display(Name = "CompanyName")]
        public string CompanyName { get; set; }
        [Required(ErrorMessage = "Please Enter Short Name")]
        [Display(Name = "ShortName")]
        public string ShortName { get; set; }
        [Required(ErrorMessage = "Please Enter Email Address")]
        [Display(Name = "Email")]
        public string Email { get; set; }
        [Required(ErrorMessage = "Please Enter Email Address")]
        [Display(Name = "Country")]
        public string Country { get; set; }
        [Required(ErrorMessage = "Please Enter Mobile No")]
        [Display(Name = "MobileNo")]
        public string MobileNo { get; set; }
        public Int32? IPAddress { get; set; }
    }

将IP地址存储为字符串而不是Int32

请使用此处的代码获取IP地址

我不知道HiddenFor，因为我以前没有使用过它。
我以前是如何隐藏字段的：

@Html.TextBoxFor(model => model.IPAddress, new { @class = "sr-only", @type = "hidden" })

cmp.IPAddress = Request.Form["IPAddress"];

您可以添加引导类sr only，以确保它是隐藏的。
确保检查浏览器检查器以查看隐藏字段是否有值

如果已过账但仍未保存，请在保存前尝试将IpAddress标识分配给表单字段值，如下所示：

@Html.TextBoxFor(model => model.IPAddress, new { @class = "sr-only", @type = "hidden" })

cmp.IPAddress = Request.Form["IPAddress"];
