我怎样才能呈现验证消息的HTML ASP.NET MVC？ [英] How can I render html in validation message in ASP.NET MVC?

问题描述

我目前正在开发一个注册页面。当用户已经存在我想提供登录名和密码重置链接，用户在错误信息的电子邮件领域。在控制器我有：

  [HttpPost]
公众的ActionResult注册（注​​册RegistrationModel）
{
  ...  如果（userExists）
  {
      常量字符串的errorMessage =用户已经存在，你可以和LT; A HREF =/帐号/登录＆GT;登录和LT; / A＆GT; ......;
      ModelState.AddModelError（电子邮件，的errorMessage）;
      返回视图（注册，注册）;
  }
}
 

但是，当我试图输出此消息，鉴于我没有得到我的期望。我得到的HTML标记像纯文本。 我已经试过

  @using（Html.BeginForm（））
{
＆LT; D​​IV＆GT; @ Html.TextBoxFor（M = GT; m.Email）
@ {
   @ Html.ValidationMessageFor（M = GT; m.Email）   ...   @ Html.Raw（Html.ValidationMessageFor（M = GT; m.Email））   ...   串validationMessage = Html.ValidationMessageFor（M =＆GT; m.Email）的ToString（）;
   @ Html.Raw（validationMessage）   ...   串validationMessage = Html.ValidationMessageFor（M =＆GT; m.Email）.ToHtmlString（）;
   @ Html.Raw（validationMessage）   ...   串validationMessage = Html.ValidationMessageFor（M =＆GT; m.Email）的ToString（）;
   @（新HtmlString（validationMessage））   ...   串validationMessage = Html.ValidationMessageFor（M =＆GT; m.Email）.ToHtmlString（）;
   @（新HtmlString（validationMessage））   ...   串validationMessage = Html.ValidationMessageFor（M =＆GT; m.Email）的ToString（）;
   @（新MvcHtmlString（validationMessage））   ...   串validationMessage = Html.ValidationMessageFor（M =＆GT; m.Email）.ToHtmlString（）;
   @（新MvcHtmlString（validationMessage））}
＆LT; / DIV＆GT;
}
 

解决方案

  @ Html.Raw（HttpUtility.HtmlDe code（Html.ValidationMessageFor（M = GT; m.Email ）.ToHtmlString（）））
 

是不是pretty虽然

I am currently developing a registration page. When user already exists I want to provide login and reset password links for user in error message for email field. In controller I have:

[HttpPost]
public ActionResult Register(RegistrationModel registration)
{
  ...

  if(userExists)
  {
      const string errorMessage = "User already exist. You can <a href="/account/login">login</a> ...";
      ModelState.AddModelError("Email", errorMessage);
      return View("Register", registration);
  }
}

But when I try to output this message in view I do not get what I expect. I get html markup like plain text. I've already tried:

@using(Html.BeginForm())
{
<div>@Html.TextBoxFor(m => m.Email)            
@{
   @Html.ValidationMessageFor(m => m.Email)

   ...

   @Html.Raw(Html.ValidationMessageFor(m => m.Email))

   ...

   string validationMessage = Html.ValidationMessageFor(m => m.Email).ToString();
   @Html.Raw(validationMessage)

   ...

   string validationMessage = Html.ValidationMessageFor(m => m.Email).ToHtmlString();
   @Html.Raw(validationMessage)

   ...

   string validationMessage = Html.ValidationMessageFor(m => m.Email).ToString();
   @(new HtmlString(validationMessage))

   ...

   string validationMessage = Html.ValidationMessageFor(m => m.Email).ToHtmlString();
   @(new HtmlString(validationMessage))

   ...

   string validationMessage = Html.ValidationMessageFor(m => m.Email).ToString();
   @(new MvcHtmlString(validationMessage))

   ...

   string validationMessage = Html.ValidationMessageFor(m => m.Email).ToHtmlString();
   @(new MvcHtmlString(validationMessage))

}
</div>
}

解决方案

@Html.Raw(HttpUtility.HtmlDecode(Html.ValidationMessageFor(m => m.Email).ToHtmlString()))

Isn't pretty though
