ASP.NET MVC - HybridViewResult（的ViewResult / PartialViewResult） [英] ASP.NET MVC - HybridViewResult (ViewResult /PartialViewResult)

问题描述

是否有可能建立一个混合的ViewResult，在一个AjaxRequest的depedency返回或Htt的prequest一个 PartialViewResult 或的ViewResult ？

Is it possible to build a hybrid ViewResult that returns in depedency of an AjaxRequest or HttpRequest a PartialViewResult or ViewResult?

IsAjaxRequest - >回PartialViewResult
！IsAjaxRequest - >返回的ViewResult

IsAjaxRequest --> return PartialViewResult !IsAjaxRequest --> return ViewResult

据我知道我应该HybridViewResult从ViewResultBase派生。

As far as I know my HybridViewResult should derive from ViewResultBase.

但如何实现FindView方法？

But how to implement the FindView method?

推荐答案

尝试：

public class HybridViewResult : ActionResult
{
    public string ViewName { get; set; }
    public HybridViewResult () { }
    public HybridViewResult (string viewName ) { this.ViewName = viewName ; }
    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null) throw new ArgumentNullException("context");
        var usePartial = ShouldUsePartial();
        ActionResult res = GetInnerViewResult(usePartial);
        res.ExecuteResult(context);
    }
    private ActionResult GetInnerViewResult(bool usePartial)
    {
        var view = ViewName;
        ActionResult res;
        if(String.IsNullOrEmpty(view)) {
             res = usePartial ? new PartialViewResult(view) : new ViewResult(view);
        }
        else {
             res = usePartial ? new PartialViewResult() : new ViewResult();
        }
        return res;
    }
    private bool ShouldUsePartial(ControllerContext context) {
        return false; //your code that checks if you need to use partial here
    }
}

添加任何构造函数和放大器; GetInnerViewResult变化需要，即通过模型。

Add any constructor & GetInnerViewResult variations as needed i.e. to pass Model.
