我想在Orchard CMS中将RazorView渲染为字符串,但我不知道如何获取部分视图的链接以获取字符串。
public string RenderRazorViewToString(string viewName, object model)
{
ViewData.Model = model;
using (var sw = new StringWriter())
{
var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
var viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
viewResult.View.Render(viewContext, sw);
viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);
return sw.GetStringBuilder().ToString();
}
}
如果在另一个MVC项目中 - 而不是Orchard - 它可以正常使用代码:
string result = RenderRazorViewToString("~/Views/Home/PartialViewEmail.cshtml", null);
但是在Orchard CMS中,它不知道从哪里获得部分视图。
我该怎么办?
非常感谢!

然而,更好的解决方案是采用Orchard的做事方式,使用形状。如果你这样做:
@Display.ViewEmail(SomeParameter: 42, SomeOtherParameter: "foo")
然后在名为/Views
的{{1}}下的主题中创建一个文件,如果需要,可以引用作为ViewEmail.cshtml
属性传入的参数。对Model
的调用将导致呈现Display
形状。

我已经解决了这个问题。这很简单,如下面
PartialViewResult path = PartialView("PartialViewEmail");
string tmp = path.ViewName;
string result = RenderRazorViewToString(tmp, null);

我选择了以下扩展方法:
public static class ViewExtensions
{
public static string RenderToString(this PartialViewResult partialView)
{
var httpContext = HttpContext.Current;
if (httpContext == null)
{
throw new NotSupportedException("An HTTP context is required to render the partial view to a string");
}
var controllerName = httpContext.Request.RequestContext.RouteData.Values["controller"].ToString();
var controller = (ControllerBase)ControllerBuilder.Current.GetControllerFactory().CreateController(httpContext.Request.RequestContext, controllerName);
var controllerContext = new ControllerContext(httpContext.Request.RequestContext, controller);
var view = ViewEngines.Engines.FindPartialView(controllerContext, partialView.ViewName).View;
var sb = new StringBuilder();
using (var sw = new StringWriter(sb))
{
using (var tw = new HtmlTextWriter(sw))
{
view.Render(new ViewContext(controllerContext, view, partialView.ViewData, partialView.TempData, tw), tw);
}
}
return sb.ToString();
}
}
它允许我执行以下操作:
var html = PartialView("SomeView").RenderToString();
如果由于某种原因我仍想获得视图的完整路径,我可以执行以下操作:
var path = ((BuildManagerCompiledView)view).ViewPath; // Will be something like "~/Views/Shared/SomeView.cshtml"
