using System.ComponentModel.DataAnnotations; using System.Web.Mvc; namespace Ninesky.Web.Areas.Control.Models { /// <summary> /// 添加用户视图模型类 /// </summary> public class AddUserViewModel { /// <summary> /// 角色ID /// </summary> [Required(ErrorMessage = "必须选择{0}")] [Display(Name = "角色ID")] public int RoleID { get; set; } /// <summary> /// 用户名 /// </summary> [Remote("CanUsername","User",HttpMethod = "Post", ErrorMessage ="用户名已存在")] [StringLength(50, MinimumLength = 4, ErrorMessage = "{0}长度为{2}-{1}个字符")] [Required(ErrorMessage = "必须输入{0}")] [Display(Name = "用户名")] public string Username { get; set; } /// <summary> /// 姓名【可做昵称、真实姓名等】 /// </summary> [StringLength(20, ErrorMessage = "{0}必须少于{1}个字符")] [Display(Name = "姓名")] public string Name { get; set; } /// <summary> /// 性别【0-女，1-男，2-保密】 /// </summary> [Required(ErrorMessage = "必须选择{0}")] [Range(0, 2, ErrorMessage = "{0}范围{1}-{2}")] [Display(Name = "性别")] public int Sex { get; set; } /// <summary> /// 密码 /// </summary> [Required(ErrorMessage = "必须输入{0}")] [DataType(DataType.Password)] [StringLength(256, ErrorMessage = "{0}长度少于{1}个字符")] [Display(Name = "密码")] public string Password { get; set; } /// <summary> /// 确认密码 /// </summary> [System.ComponentModel.DataAnnotations.Compare("Password",ErrorMessage ="两次输入的密码不一致")] [DataType(DataType.Password)] [Display(Name = "确认密码")] public string ConfirmPassword { get; set; } /// <summary> /// Email /// </summary> [Required(ErrorMessage = "必须输入{0}")] [DataType(DataType.EmailAddress)] [Remote("CanEmail", "User",HttpMethod = "Post", ErrorMessage = "Email已存在")] [StringLength(50, MinimumLength = 4, ErrorMessage = "{0}长度为{2}-{1}个字符")] [Display(Name = "Email")] public string Email { get; set; } } }
模型中使用到了远程验证（Remote）、属性比较（Compare）等验证方式。
2.2用户名和Email远程验证方法
在UserController中添加CanUsername和CanEmail方法
/// <summary> /// 用户名是否可用 /// </summary> /// <param>用户名</param> /// <returns></returns> [HttpPost] public JsonResult CanUsername(string UserName) { return Json(!userManager.HasUsername(UserName)); } /// <summary> /// Email是否存可用 /// </summary> /// <param>Email</param> /// <returns></returns> [HttpPost] public JsonResult CanEmail(string Email) { return Json(!userManager.HasEmail(Email)); }
2.3 添加用户页面
在UserController中添加Add方法
/// <summary> /// 添加用户 /// </summary> /// <returns></returns> public ActionResult Add() { //角色列表 var _roles = new RoleManager().FindList(); List<SelectListItem> _listItems = new List<SelectListItem>(_roles.Count()); foreach(var _role in _roles) { _listItems.Add(new SelectListItem() { Text = _role.Name, Value = _role.RoleID.ToString() }); } ViewBag.Roles = _listItems; //角色列表结束 return View(); }
方法中向视图传递角色列表ViewBag.Roles
右键添加视图
代码如下：
@model Ninesky.Web.Areas.Control.Models.AddUserViewModel @{ ViewBag.Title = "添加用户"; } @section SideNav{@Html.Partial("SideNavPartialView")} <ol> <li><span></span> @Html.ActionLink("首页", "Index", "Home")</li> <li> @Html.ActionLink("用户管理", "Index", "User")</li> <li>@Html.ActionLink("添加用户", "Add", "User")</li> </ol> @using (Html.BeginForm()) { @Html.AntiForgeryToken() <div> <hr /> @Html.ValidationSummary(true, "", new { @class = "text-danger" }) <div> @Html.LabelFor(model => model.RoleID, htmlAttributes: new { @class = "control-label col-md-2" }) <div> @Html.DropDownListFor(model => model.RoleID, (IEnumerable<SelectListItem>)ViewBag.Roles, new { @class = "form-control" }); @Html.ValidationMessageFor(model => model.RoleID, "", new { @class = "text-danger" }) </div> </div> <div> @Html.LabelFor(model => model.Username, htmlAttributes: new { @class = "control-label col-md-2" }) <div> @Html.EditorFor(model => model.Username, new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" }) </div> </div> <div> @Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" }) <div> @Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" }) </div> </div> <div> @Html.LabelFor(model => model.Sex, htmlAttributes: new { @class = "control-label col-md-2" }) <div> @Html.RadioButtonFor(model => model.Sex, 1) 男 @Html.RadioButtonFor(model => model.Sex, 0) 女 @Html.RadioButtonFor(model => model.Sex, 2) 保密 @Html.ValidationMessageFor(model => model.Sex, "", new { @class = "text-danger" }) </div> </div> <div> @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" }) <div> @Html.EditorFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" }) </div> </div> <div> @Html.LabelFor(model => model.ConfirmPassword, htmlAttributes: new { @class = "control-label col-md-2" }) <div> @Html.EditorFor(model => model.ConfirmPassword, new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.ConfirmPassword, "", new { @class = "text-danger" }) </div> </div> <div> @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" }) <div> @Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" }) </div> </div> <div> <div> <input type="submit" value="添加" /> </div> </div> </div> } @Scripts.Render("~/bundles/jqueryval")
2.4添加处理方法
UserController中添加Add(AddUserViewModel userViewModel)方法
