如何將ASP.NET MVC視圖呈現(xiàn)為字符串？我想輸出兩個不同的視圖（一個作為將作為電子郵件發(fā)送的字符串），另一個顯示給用戶的頁面。這是否可以在ASP.NET MVC beta中使用？我嘗試過多個例子：1. ASP.NET MVC Beta中的RenderPartial到String如果我使用此示例，則會收到“在HTTP標頭發(fā)送后無法重定向”。2. MVC框架：捕獲視圖的輸出如果我使用它，我似乎無法執(zhí)行redirectToAction，因為它嘗試渲染可能不存在的視圖。如果我確實返回了視圖，那么它完全搞砸了，看起來根本不正確。有沒有人對我遇到的這些問題有任何想法/解決方案，或者對更好的問題有任何建議？非常感謝！以下是一個例子。我要做的是創(chuàng)建GetViewForEmail方法：public ActionResult OrderResult(string ref){
//Get the order
Order order = OrderService.GetOrder(ref);
//The email helper would do the meat and veg by getting the view as a string
//Pass the control name (OrderResultEmail) and the model (order)
string emailView = GetViewForEmail("OrderResultEmail", order);
//Email the order out
EmailHelper(order, emailView);
return View("OrderResult", order);}Tim Scott接受的答案（由我改變并格式化）：public virtual string RenderViewToString(
ControllerContext controllerContext,
string viewPath,
string masterPath,
ViewDataDictionary viewData,
TempDataDictionary tempData){
Stream filter = null;
ViewPage viewPage = new ViewPage();
//Right, create our view
viewPage.ViewContext = new ViewContext(controllerContext, new WebFormView(viewPath, masterPath), viewData, tempData);
//Get the response context, flush it and get the response filter.
var response = viewPage.ViewContext.HttpContext.Response;
response.Flush();
var oldFilter = response.Filter;
try
{
//Put a new filter into the response
filter = new MemoryStream();
response.Filter = filter;
//Now render the view into the memorystream and flush the response
viewPage.ViewContext.View.Render(viewPage.ViewContext, viewPage.ViewContext.HttpContext.Response.Output);
response.Flush();
//Now read the rendered view.
filter.Position = 0;
var reader = new StreamReader(filter, response.ContentEncoding);
return reader.ReadToEnd();
}
