Question

我有以下观点：

@model MyProject.Models.RegisterViewModel

<div class="content">
<div class="wrapper">
    <h2>E-Bill Saver Registration</h2>
    <hr />

    <div class="columns top-gap">
        <div class="first cell width-6 dark-blue-headings">
            @using (Html.BeginForm())
            {
                @Html.AntiForgeryToken()
                @*@Html.ValidationSummary("", new { @class = "text-danger" })*@
                <div class="form-horizontal">                        
                    <div class="form-group">
                        @Html.Label("Account Number", htmlAttributes: new { @class = "control-label col-md-2 bold" })
                        <br />@Html.ValidationMessageFor(model => model.AccountNo, "", new { @class = "text-danger" })
                        <div class="col-md-10">
                            @Html.EditorFor(model => model.AccountNo, new { htmlAttributes = new { @class = "form-control input" } })
                        </div>

                    <div class="form-group">
                        @Html.Label("MPNumber", htmlAttributes: new { @class = "control-label col-md-2 bold" })

                    </div>

                    <div class="form-group">
                        @Html.Label("Email Address", htmlAttributes: new { @class = "control-label col-md-2 bold" })
                        <br />@Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })
                        <div class="col-md-10">
                            @Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control input" } })

                    <div class="form-group">
                        @Html.Label("Confirm Email Address", htmlAttributes: new { @class = "control-label col-md-2 bold" })
                        <br />@Html.ValidationMessageFor(model => model.ConfirmEmail, "", new { @class = "text-danger" })
                        <div class="col-md-10">

                        </div>
                    </div>

                    <div class="form-group">
                        @Html.Label("Password", htmlAttributes: new { @class = "control-label col-md-2 bold" })
                        <br />@Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" })
                        <div class="col-md-10">
                            @Html.EditorFor(model => model.Password, new { htmlAttributes = new { @class = "form-control input" } })
                        </div>
                    </div>

                    <div class="form-group">
                        @Html.Label("Confirm Password", htmlAttributes: new { @class = "control-label col-md-2 bold" })
                        <br />@Html.ValidationMessageFor(model => model.ConfirmPassword, "", new { @class = "text-danger" })
                        <div class="col-md-10">
                            @Html.EditorFor(model => model.ConfirmPassword, new { htmlAttributes = new { @class = "form-control input" } })
                        </div>
                    </div>

                    <div class="form-group">
                        <div class="col-md-offset-2 col-md-10">
                            <input type="submit" value="Register" class="opc_button" />
                        </div>
                    </div>
                </div>
            }
        </div>
    </div>       
</div>

如果任何字段上存在验证错误，则错误消息将按预期和需要显示在标签下方。然而，在我的控制器上，我有一些自定义逻辑错误，我将它们添加到模型状态，如下所示：

else
                {
                    //This email address is already assigned to a user      
                    ModelState.AddModelError("Email Address : ", "Error! You must enter an email address that is unique to your account.");
                    return View(model);
                }

如果我取消注释页面上的validationsummary，那么它将显示自定义服务器端错误，但它也会在标签下方显示我想要的单个验证错误。有没有什么办法可以设置验证摘要来忽略单独列出的值，只返回服务器端验证错误？

ModelState.AddModelError方法的第一个字符串参数是稍后用于将消息绑定到模型属性的键如果要在电子邮件标签旁边显示该错误消息，请将AddModelError的第一个参数与您的媒体资源名称相匹配：

ModelState.AddModelError("Email", "Error! Email already used...");

在验证摘要中仅显示服务器端错误
