使用破折号（ - ）在ASP.MVC参数 [英] Using a dash (-) in ASP.MVC parameters

问题描述

<% using (Html.BeginForm("SubmitUserName")) { %>
    <input type='text' name='user-name' />
    <input type='submit' value='Send' />
<% } %>

应该是什么相应的动作方法的签名接受用户名参数？

public ActionResult SubmitUserName(string user-name) {...}

方法签名上面并没有出于某种原因; - ）

Method signature above does not work for some reason ;-)

我知道有一个 ActionNameAttribute 来处理与操作名称短划线的情况。有什么样 ParameterNameAttribute ？

I know there is an ActionNameAttribute to handle situation with a dash in action name. Is there something like ParameterNameAttribute?

推荐答案

因为每个人都有所指出的，最简单的解决方法是不再使用破折号。如果你真的需要短跑，你可以创建自己的ActionFilterAttribute来处理它，但。

As everyone has noted, the easiest fix would be not to use a dash. If you truly need the dash, you can create your own ActionFilterAttribute to handle it, though.

是这样的：

[AttributeUsage(AttributeTargets.Method, AllowMultiple = true)]
public class ParameterNameAttribute :  ActionFilterAttribute
{
    public string ViewParameterName { get; set; }
    public string ActionParameterName { get; set; }

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if(filterContext.ActionParameters.ContainsKey(ViewParameterName))
        {
            var parameterValue = filterContext.ActionParameters[ViewParameterName];
            filterContext.ActionParameters.Add(ActionParameterName, parameterValue);   
        }
    }
}

然后，您可以将过滤器应用于适当的行动方式：

You would then apply the filter to the appropriate Action method:

[ParameterName( ViewParameterName = "user-data", ActionParameterName = "userData")]
[ParameterName( ViewParameterName = "my-data", ActionParameterName = "myData" )]
    public ActionResult About(string userData, string myData)
    {
        return View();
    }

您可能会想增强ParameterNameAttribute处理/小写，但是这将是基本思想。

You would probably want to enhance the ParameterNameAttribute to handle upper/lower case, but that would be the basic idea.
