修改

if (user != null) {
return View(user);
} else {
return RedirectToAction("Index");
}
} [HttpPost]
public async Task<ActionResult> Edit(string id, string email, string password) {
ApplicationUser user = await _userManager.FindByIdAsync(id);
if (user != null) {
user.PasswordHash =_userManager.PasswordHasher.HashPassword(user,password);
IdentityResult result = await _userManager.UpdateAsync(user);
if (result.Succeeded) {
return RedirectToAction("Index");
} else {
AddErrors(result);
}
} else {
ModelState.AddModelError("", "User Not Found");
}
return View(user);
}

Views->Account->Edit.cshtml

@model ApplicationUser
@{ ViewBag.Title = "Edit"; }
@Html.ValidationSummary(false)
<h2>Edit User</h2> <div class="form-group">

<p class="form-control-static">@Model.Id</p>
</div>
@using (Html.BeginForm()) {

@Html.TextBoxFor(x => x.Email, new { @class = "form-control" })
</div>
<div class="form-group">

</div>
<button type="submit" class="btn btn-primary">Save</button>
@Html.ActionLink("Cancel", "Index", null, new { @class = "btn btn-default" })
}

Views ->Shared->_Layout.cshtml 加一个主跳转连接

  <div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li><a asp-area="" asp-controller="Home" asp-action="Index">Home</a></li>
<li><a asp-area="" asp-controller="Home" asp-action="About">About</a></li>
<li><a asp-area="" asp-controller="Home" asp-action="Contact">Contact</a></li>
<li><a asp-area="" asp-controller="Account" asp-action="Index">Account</a></li> //加这句
