.NET MVC Masking Password textboxes
提问by ewahner
I was under the impression that using an annotation like this:
我的印象是使用这样的注释：
<Required()>
<DisplayName("Choose a Password:")>
<ValidatePasswordLength()>
<DataType(DataType.Password)>
Public Property Password As String
Would create a masked field when used in the view:
在视图中使用时会创建一个屏蔽字段：
<%: Html.TextBoxFor(Function(model) model.Password) %>
<%: Html.ValidationMessageFor(Function(model) model.Password) %>
However this is rendered without the type="password"
然而，这是在没有 type="password" 的情况下呈现的
What is the "DataType.Password" used for if not this?
如果不是这个，“DataType.Password”是做什么用的？

TextBoxForoverrides your annotation because it indicates a clear text input. As marcind mentioned, EditorForhonors the annotation or you could use PasswordForfor that field.
TextBoxFor覆盖您的注释，因为它指示明文输入。正如 marcind 所提到的，EditorFor尊重注释或者您可以PasswordFor用于该领域。

You are using Html.TextBoxForwhich always outputs an <input type="text">tag in the resulting HTML.
If you want the DataType.Password annotation to be automatically honored you should use Html.EditorForinstead.

您正在使用Html.TextBoxForwhich 始终<input type="text">在结果 HTML 中输出一个标签。如果您希望自动遵守 DataType.Password 注释，则应Html.EditorFor改用。您可以在此处阅读有关编辑器模板以及如何自定义它们的更多信息：http: //bradwilson.typepad.com/blog/2009/10/aspnet-mvc-2-templates-part-1-introduction.html
