C# 在asp.net控件中使用asp.net mvc视图
以下代码将asp.net webforms控件添加到webforms应用程序中的“我的内容占位符”:C# 在asp.net控件中使用asp.net mvc视图,c#,asp.net,asp.net-mvc,C#,Asp.net,Asp.net Mvc,以下代码将asp.net webforms控件添加到webforms应用程序中的“我的内容占位符”: var someControl = (System.Web.UI.UserControl)LoadControl("~/serverPath/" + ControlName + ".ascx"); phContentControls.Controls.Add(someControl); 所以我想知道是否有任何方法可以将呈现的asp.net mvc视图添加到控件中 天哪,wtf我刚才问:你可以试
var someControl = (System.Web.UI.UserControl)LoadControl("~/serverPath/" + ControlName + ".ascx");
phContentControls.Controls.Add(someControl);
所以我想知道是否有任何方法可以将呈现的asp.net mvc视图添加到控件中
天哪,wtf我刚才问:你可以试着做如下事情: 当我想在Webforms页面中呈现PartialView或ChildActions时,我会使用这个MvcUtility类,但我不认为我在UserControl中使用过它 不确定您使用的是哪个MVC版本,但我知道这适用于MVC 3和Razor视图
public static class MvcUtility
{
public static void RenderPartial(string partialViewName, object model)
{
// Get the HttpContext
HttpContextBase httpContextBase = new HttpContextWrapper(HttpContext.Current);
// Build the route data, pointing to the Some controller
RouteData routeData = new RouteData();
routeData.Values.Add("controller", typeof(Controller).Name);
// Create the controller context
ControllerContext controllerContext = new ControllerContext(new RequestContext(httpContextBase, routeData), new Controller());
// Find the partial view
IView view = FindPartialView(controllerContext, partialViewName);
// create the view context and pass in the model
ViewContext viewContext = new ViewContext(controllerContext, view, new ViewDataDictionary { Model = model }, new TempDataDictionary(), httpContextBase.Response.Output);
// finally, render the view
view.Render(viewContext, httpContextBase.Response.Output);
}
private static IView FindPartialView(ControllerContext controllerContext, string partialViewName)
{
// try to find the partial view
ViewEngineResult result = ViewEngines.Engines.FindPartialView(controllerContext, partialViewName);
if (result.View != null)
{
return result.View;
}
// wasn't found - construct error message
StringBuilder locationsText = new StringBuilder();
foreach (string location in result.SearchedLocations)
{
locationsText.AppendLine();
locationsText.Append(location);
}
throw new InvalidOperationException(String.Format("Partial view {0} not found. Locations Searched: {1}", partialViewName, locationsText));
}
public static void RenderAction(string controllerName, string actionName, object routeValues)
{
RenderPartial("RenderActionUtil", new RenderActionVM() { ControllerName = controllerName, ActionName = actionName, RouteValues = routeValues });
}
}
要渲染ChildAction,您需要共享MVC视图文件夹中的局部视图:
@model YourNamespace.RenderActionVM
@{
Html.RenderAction(Model.ActionName, Model.ControllerName, Model.RouteValues);
}
以及视图模型:
public class RenderActionVM
{
public string ControllerName { get; set; }
public string ActionName { get; set; }
public object RouteValues { get; set; }
}
最后,在您的webforms页面中,如下调用:
<% MvcUtility.RenderPartial("_SomePartial", null); %>
<% MvcUtility.RenderAction("SomeController", "SomeAction", new { accountID = Request.QueryString["id"], dateTime = DateTime.Now }); %>
