Web Api控制器可以將視圖呈現爲字符串嗎？

Question

我想編寫一個Web Api控制器操作，根據結果發送一封電子郵件。我想使用MVC視圖或部分視圖以及數據模型來呈現電子郵件的正文。

有沒有辦法做到這一點？

我想是這樣的：

public class NotificationApiController : ApiController 
{ 
    private IMkpContext db; 

    public string ViewNotifications() 
    { 
     var dataModel = GetDataModel(); 
     if (dataModel != null) 
     { 
      SendEmail(dataModel.ToAddress, dataModel.FromAddress, dataModel.Subject, RenderBody("viewName", dataModel); 
     } 

     return string.Empty; 
    } 
} 

凡RenderBody會擡頭看的viewName，從數據模型填充數據，並渲染視圖作爲字符串。

如果你不想將去與RazorEngine方法建議在評論中，你可以像這樣定義一個類：

public static class ViewUtil 
{ 
    public static string RenderPartial(string partialName, object model) 
    { 
     var sw = new StringWriter(); 
     var httpContext = new HttpContextWrapper(HttpContext.Current); 

     // point to an empty controller 
     var routeData = new RouteData(); 
     routeData.Values.Add("controller", "EmptyController"); 

     var controllerContext = new ControllerContext(new RequestContext(httpContext, routeData), new EmptyController()); 

     var view = ViewEngines.Engines.FindPartialView(controllerContext, partialName).View; 

     view.Render(new ViewContext(controllerContext, view, new ViewDataDictionary { Model = model }, new TempDataDictionary(), sw), sw); 

     return sw.ToString(); 
    } 
} 

class EmptyController : Controller { }
