为了发送电子邮件,我正在使用此代码尝试将剃刀部分视图呈现为字符串。
public static string RenderPartialToString(
string userControlPath,
object viewModel,
ControllerContext controllerContext,
TempDataDictionary tempData)
{
using (var writer = new StringWriter())
{
var viewDataDictionary = new ViewDataDictionary(viewModel);
var view = new WebFormView(controllerContext, userControlPath);
var viewContext = new ViewContext(
controllerContext,
view,
viewDataDictionary,
tempData,
writer
);
viewContext.View.Render(viewContext, writer);
return writer.GetStringBuilder().ToString();
}
}
问题是我收到以下错误:
must derive from ViewPage, ViewPage<TModel>, ViewUserControl, or ViewUserControl<TModel>. Stack Trace: at System.Web.Mvc.WebFormView.RenderView(ViewContext viewContext, TextWriter writer, Object instance) at .... RenderPartialToString
我将如何解决这个问题?
