我有一个应用程序,管理员可以在电子邮件中完成订单并将其副本保存在服务器中之后,让用户在电子邮件中订购详细信息。我有一个视图“〜/ order / MyOrder.cshtml?id = Q5 / KCbPNhXKx7EWffTprWg ==”,用户登录后即可查看以查看其状态。但是,当订单完成后,管理员会向用户发送一封电子邮件,其中包含订单状态以及所有信息的pdf文件。我正在尝试从上述视图创建pdf文件,并计划将该文件附加到电子邮件中。最佳方法是什么?我在这里看到的解决方案很少,但是我无法弄清楚如何解决这个问题。我为此使用ITexSharp。
string html = RenderViewToString(ControllerContext,
"/order/MyOrder.cshtml?Auth=Q5/KCbPNhXKx7EWffTprWg==",
model, true);
using (MemoryStream stream = new System.IO.MemoryStream())
{
StringReader sr = new StringReader(html);
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, stream);
pdfDoc.Open();
XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);
pdfDoc.Close();
var Filename = File(stream.ToArray(), "application/pdf", "Grid.pdf");
zip.AddFile(Filename.FileDownloadName, "Pdf");
}
和RanderViewToString函数:
static string RenderViewToString(ControllerContext context,
string viewPath,
object model = null,
bool partial = false)
{
// first find the ViewEngine for this view
ViewEngineResult viewEngineResult = null;
if (partial)
viewEngineResult = ViewEngines.Engines.FindPartialView(context, viewPath);
else
viewEngineResult = ViewEngines.Engines.FindView(context, viewPath, null);
if (viewEngineResult == null)
throw new FileNotFoundException("View cannot be found.");
// get the view and attach the model to view data
var view = viewEngineResult.View;
context.Controller.ViewData.Model = model;
string result = null;
using (var sw = new StringWriter())
{
var ctx = new ViewContext(context, view,
context.Controller.ViewData,
context.Controller.TempData,
sw);
view.Render(ctx, sw);
result = sw.ToString();
}
return result;
}
我收到“值不能为null。参数名称:view'”错误。我不确定如何通过带有参数的视图将其转换为字符串。

我建议您尝试Rotativa
https://github.com/webgio/Rotativa
public ActionResult PrintIndex()
{
return new ActionAsPdf("Index", new { name = "Giorgio" }) { FileName = "Test.pdf" };
}
