ASP.NET Identity教程二：（用户管理6）修改用户密码

一，在ViewModels下新建模型ChangePasswordViewModel

using System.ComponentModel.DataAnnotations;

namespace jsdhh2.ViewModels
{
	public class ChangePasswordViewModel
	{
		[Required]
		[DataType(DataType.Password)]
		[Display(Name = "当前密码")]
		public string OldPassword { get; set; }

		[Required]
		[StringLength(100, ErrorMessage = "{0} 必须至少包含 {2} 个字符。", MinimumLength = 6)]
		[DataType(DataType.Password)]
		[Display(Name = "新密码")]
		public string NewPassword { get; set; }

		[DataType(DataType.Password)]
		[Display(Name = "确认新密码")]
		[Compare("NewPassword", ErrorMessage = "新密码和确认密码不匹配。")]
		public string ConfirmPassword { get; set; }

	}


}

　　

二、在UserController中新建两个方法

//
		//        // GET: /Manage/ChangePassword
		public ActionResult ChangePassword()
		{
			return View();
		}


		// POST: /Manage/ChangePassword
		[HttpPost]
		[ValidateAntiForgeryToken]
		public async Task<ActionResult> ChangePassword(jsdhh2.ViewModels.ChangePasswordViewModel model)
		{
			if (!ModelState.IsValid)
			{
				return View(model);
			}
			var result = await UserManager.ChangePasswordAsync(User.Identity.GetUserId(), model.OldPassword, model.NewPassword);
			if (result.Succeeded)
			{
				var user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
				if (user != null)
				{
					await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);
				}
				return RedirectToAction("Login", "User");
			}
			AddErrors(result);
			return View(model);
		}

　　5.新建一个ChangePassword视图

@model jsdhh2.ViewModels.ChangePasswordViewModel
@{
	ViewBag.Title = "更改密码";
}

<h2>@ViewBag.Title。</h2>

@using (Html.BeginForm("ChangePassword", "Manage", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
	@Html.AntiForgeryToken()
	<h4>更改密码表单</h4>
	<hr />
	@Html.ValidationSummary("", new { @class = "text-danger" })
	<div class="form-group">
		@Html.LabelFor(m => m.OldPassword, new { @class = "col-md-2 control-label" })
		<div class="col-md-10">
			@Html.PasswordFor(m => m.OldPassword, new { @class = "form-control" })
		</div>
	</div>
	<div class="form-group">
		@Html.LabelFor(m => m.NewPassword, new { @class = "col-md-2 control-label" })
		<div class="col-md-10">
			@Html.PasswordFor(m => m.NewPassword, new { @class = "form-control" })
		</div>
	</div>
	<div class="form-group">
		@Html.LabelFor(m => m.ConfirmPassword, new { @class = "col-md-2 control-label" })
		<div class="col-md-10">
			@Html.PasswordFor(m => m.ConfirmPassword, new { @class = "form-control" })
		</div>
	</div>
	<div class="form-group">
		<div class="col-md-offset-2 col-md-10">
			<input type="submit" value="更改密码" class="btn btn-default" />
		</div>
	</div>
}
@section Scripts {
	@Scripts.Render("~/bundles/jqueryval")
}
