模型中的Rotativa PDF - ControllerContext

我正在使用Rotativa从actions/views生成PDF，并且它工作得非常好。然而，它可能在模型中使用它，或者你可以纯粹在控制器中使用它吗？模型中的Rotativa PDF - ControllerContext

的问题是功能要使用ControllerContext该款机型没有

var pdfResult = new ActionAsPdf("GeneratePDF", "PDF"); 

byte[] pdfFile = pdfResult.BuildPdf(this.ControllerContext);

我的最终结果是，我想在一个字节数组的PDF如果有做

的其他方式

您可以使用以下代码实例化控制器，然后通过该实例配置ControllerContext - 从应用程序中的任何位置进行配置。

/// <summary> 
/// Creates an instance of an MVC controller from scratch 
/// when no existing ControllerContext is present  
/// </summary> 
/// <typeparam name="T">Type of the controller to create</typeparam> 
/// <returns>Controller Context for T</returns> 
/// <exception cref="InvalidOperationException">thrown if HttpContext not available</exception> 
public static T CreateController<T>(RouteData routeData = null) 
      where T : Controller, new() 
{ 
    // create a disconnected controller instance 
    T controller = new T(); 

    // get context wrapper from HttpContext if available 
    HttpContextBase wrapper = null; 
    if (HttpContext.Current != null) 
     wrapper = new HttpContextWrapper(System.Web.HttpContext.Current); 
    else 
     throw new InvalidOperationException(
      "Can't create Controller Context if no active HttpContext instance is available."); 

    if (routeData == null) 
     routeData = new RouteData(); 

    // add the controller routing if not existing 
    if (!routeData.Values.ContainsKey("controller") && !routeData.Values.ContainsKey("Controller")) 
     routeData.Values.Add("controller", controller.GetType().Name 
                .ToLower() 
                .Replace("controller", "")); 

    controller.ControllerContext = new ControllerContext(wrapper, routeData, controller); 
    return controller; 
}

这可用于这样的：

QuotesController quotesController = ViewRenderer.CreateController<QuotesController>(); 
ViewAsPdf view = (ViewAsPdf)quotesController.Preview(model.Guid); 
byte[] pdf = view.BuildPdf(quotesController.ControllerContext); 
EmailService.Send(model, pdf);
