无法使用[EmailAddress]注释仅验证电子邮件验证中的空间

Question

我正在使用[EmailAddress] data annotation来验证电子邮件地址。我注意到如果我增加空间而不是工作。如果我使用句号，连字符，下划线但空格，它工作正常。

型号：

[DisplayName(@"Custom Email Confirmation Address")]
[EmailAddress(ErrorMessage = @"Invalid Email Address")]
public string CustomEmailConfirmationAddress { get; set; }

自定义控制：

<div>
    <%=Html.RequiredLabelFor(m => m.CustomEmailConfirmationAddress) %>
    <%=Html.TextBoxFor(m => m.CustomEmailConfirmationAddress, new { maxlength = 100 })%>
    <%=Html.ValidationMessageFor(m => m.CustomEmailConfirmationAddress)%>
</div>

在浏览器上：适用于空间class="textboxhelp-focus valid"

<div>
    <label class="required" for="CustomEmailConfirmationAddress">Custom Email Confirmation Address</label>
    <input id="CustomEmailConfirmationAddress" class="textboxhelp-focus valid" type="text" value="" name="CustomEmailConfirmationAddress" maxlength="100" data-val-email="Invalid Email Address" data-val="true" help="noreply@example.com" style="width: 300px;">
    <span class="field-validation-valid" data-valmsg-replace="true" data-valmsg-for="CustomEmailConfirmationAddress"></span>
</div>

对于下划线：class="textboxhelp-focus input-validation-error"

<div>
    <label class="required" for="CustomEmailConfirmationAddress">Custom Email Confirmation Address</label>
    <input id="CustomEmailConfirmationAddress" class="textboxhelp-focus input-validation-error" type="text" value="" name="CustomEmailConfirmationAddress" maxlength="100" data-val-email="Invalid Email Address" data-val="true" help="noreply@example.com" style="width: 300px;">
    <span class="field-validation-error" data-valmsg-replace="true" data-valmsg-for="CustomEmailConfirmationAddress">
</div>

我在这里错过了什么吗？
