【问题描述】：

将 mailto 添加到此 ASP.NET MVC3 代码的正确语法是什么。这不起作用，使用双引号也不起作用：

ModelState.AddModelError("", "We could not locate the email address you entered.  Please check the email address.  If you believe it is correct, please contact us by sending an email to <a href='mailto:support@abc.com'>Support</a> from the email address you are attempting to use.");

【问题讨论】：

你的意思是“不起作用”？你得到什么 HTML？
这是浏览器中显示的内容：发送给支持的电子邮件
所以这意味着文本正在服务器端进行编码.. 担心除了添加全局 JavaScript 将其转换为实际链接之外您无能为力。如果可行，请告诉我，我会提供样品。

【解决方案1】：

我不太擅长 Razor，但这暂时可以解决您的问题

@Html.Raw(Html.ValidationSummary().ToString().Replace("[mailto]", "<a href='mailto:support@abc.com'>Support</a>"))

您的消息将包含此内容

ModelState.AddModelError("", "We could not locate the email address you entered.  Please
check the email address.  If you believe it is correct, please contact us by sending an 
email to [mailto] from the email address you are attempting to use.");

链接现在从服务器/控制器添加到视图中，用实际链接替换您的[mailto] 并调用Html.Raw 以在浏览器中呈现 html

尝试使用

添加这个 NamesPace :Using System.Text

    StringBuilder s=new StringBuilder ();
    s.Append(We could not locate the email address you entered.  Please check the email address.  If you believe it is correct, please contact us by sending an email to ");
    s.Append("<a href='mailto:support@abc.com'>Support</a>");
    s.Append("from the email address you are attempting to use.");
    ModelState.AddModelError("", s.ToString());
