如何在两个控制器操作之间避免AmbiguousMatchException?

Sai*_*udo 12 .net c# asp.net-mvc controller

我有两个具有相同名称但具有不同方法签名的控制器操作.它们看起来像这样:

    //
    // GET: /Stationery/5?asHtml=true
    [AcceptVerbs(HttpVerbs.Get)]
    public ContentResult Show(int id, bool asHtml)
    {
        if (!asHtml)
            RedirectToAction("Show", id);

        var result = Stationery.Load(id);
        return Content(result.GetHtml());
    }

    //
    // GET: /Stationery/5
    [AcceptVerbs(HttpVerbs.Get)]
    public XmlResult Show(int id)
    {
        var result = Stationery.Load(id);
        return new XmlResult(result);
    }

我的单元测试没有调用一个或另一个控制器动作的问题,但是我的测试html页面抛出了System.Reflection.AmbiguousMatchException.

<a href="/Stationery/1?asHtml=true">Show the stationery Html</a>
<a href="/Stationery/1">Show the stationery</a>

需要改变什么来使这项工作?

只要有一个像这样的方法.

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Show(int id, bool? asHtml)
{
    var result = Stationery.Load(id);

    if (asHtml.HasValue && asHtml.Value)
        return Content(result.GetHtml());
    else
        return new XmlResult(result);
}
