c# - ASP.NET MVC - HybridViewResult (ViewResult/PartialViewResult)

Question

是否有可能构建一个混合 ViewResult，它在 AjaxRequest 或 HttpRequest 的依赖中返回一个 PartialViewResult 或 ViewResult？

IsAjaxRequest --> 返回 PartialViewResult!IsAjaxRequest --> 返回 View 结果

据我所知，我的 HybridViewResult 应该派生自 ViewResultBase。

但是如何实现FindView方法呢？

Answer 1

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
    }
}

根据需要添加任何构造函数和 GetInnerViewResult 变体，即传递模型。
