Question

我遇到了这个问题;我有一个视图，我希望信息在pdf文件上。我写了一个存储过程和一个函数;但是，视图上的数据未显示在pdf文件中。除了编写存储过程，我如何在pdf文件上显示数据。

查看

 <dt>
        @Html.DisplayNameFor(model => model.docType)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.docType)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.requisitionNumber)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.requisitionNumber)
    </dd>

不幸的是，没有内置的方法可以轻松地将项目插入到文档中。我开发了许多具有类似要求的项目（将值插入PDF）。最简单的方法是通过Nuget包管理器使用Aspose框架。将Aspose添加到项目后，您只需用PDF替换PDF中的书签即可。

        Aspose.Words.License awLic = new Aspose.Words.License();
        Document doc = new Aspose.Words.Document(templateLocation);

        foreach (Bookmark bk in doc.Range.Bookmarks)
        {
            if(bk.exists())
            {                    
                bk.Text = q.answer;
            }
        }

        doc.Save(outPutLocation, SaveFormat.PDF);
