Render, Print or View Files

Aspose.Words for .NET has its own rendering engine specifically designed to render and print documents with highest fidelity. Using this feature, developers can render (draw) any page onto a .NET Graphics object while specifying the size and zoom level to create thumbnails for displaying images in a browser. Moreover, API is fully integrated with the .NET printing infrastructure and has the ability to completely customize the process so that developers can easily print or preview documents in their own applications.

Some of the rendering capabilities that API can perform:

Programming with Documents Using Document Object Model (DOM)

Aspose.Words for .NET allows you to create, build and modify documents, including document formatting, using an intuitive Document Object Model (DOM) with over 100 classes.

Here are just a few of the manipulation functions that the Words API can perform:

  • Work with whole documents: compare documents, clone documents, find and replace text, combine documents or document parts, split documents into parts and so on
  • Protect and encrypt documents, add a digital signature or watermark
  • Manage all elements including sections, headers, footers, paragraphs, lists, tables, text, fields and much more
  • Specify detailed formatting for any element, including shapes, text boxes, images, OLE objects, and controls
  • Work with complex and deeply nested expressions containing IF blocks, formulas and other fields

Reporting and Mail Merge

Aspose.Words for .NET provides an extended API syntax for mail merge fields to perform more complex operations during mail merge. You can perform a simple mail merge operation or mail merge with regions. Data for mail merge operation can come from various data tables, array of values supported by ADO .NET or custom data sources.

In addition, developers can use the LINQ Reporting Engine to generate documents from templates and data from a variety of sources, including databases, XML, JSON, OData, CLR custom type objects, external documents, and more right out of the box.

Execute simple mail merge – C#

// load the template containing merged fields

var wfle = new Aspose.Words.Document(dir + "template.doc");

// fill the fields with user data

wfle.MailMerge.Execute(

    new string[] { "FullName", "Company", "Deparment", "City" },
    
    new object[] { "John Doe", "Aspose", "Sales", "London" });

// save the result

wfle.Save(dir + "merged.doc");

No Need for Microsoft Office Automation

You can work with documents programmatically without installing any other third-party application. This is possible because the library is built using managed code. Therefore, you do not need to install Microsoft Office or Microsoft Word on your computer to work with Word formats. It is a perfect alternative to Microsoft Office Automation in terms of supported features, security, stability, scalability, speed, and price.
