C# WORDPROCESSINGDOCUMENT SAVE AS PDF

Yozuru You will find these classes in the DocumentFormat. This method does not validate the XML content in each part. MainDocumentPart wordprocessigndocument Look for the vbaProject part. You must explicitly reference the following assemblies in your project:. Copy contents of an Open XML package part to a document part in a different package Note Carefully select the appropriate WordProcessingDocumentType and verify that the persisted file has the correct, matching file extension. How the Code Works The sample code modifies the document that you specify, verifying that the document contains a vbaProject part, and deleting the part.

NET Web applications. In addition, some interesting scenarios benefit from creating an in-memory copy of an existing document. Learn how to create and work with in-memory copies of Open XML documents. However, sometimes you want to work with Open XML documents in memory. There are four main scenarios where this is interesting: When working with document libraries by using Microsoft Office SharePoint Server or SharePoint Server , you retrieve a document from the document library as a byte array.

You can then modify it as necessary, and then put it back into the document library, either as a new document, or replacing the original. When working with document libraries using the SharePoint Foundation Managed Client Object Model you access a document from the document library as a stream. After retrieving the document, you can modify it as necessary, and then stream it back into the document library. When building an ASP.

You do not want to serialize such temporary documents to the file system. After creating them, you want to send them directly to the user of the Web application.

In more traditional Open XML applications, you may want to open an Open XML document, do some temporary transformations on the document, such as accept all revisions, and then query the transformed document. In this case, you do not want to serialize the modified document back to the file system, as the temporary modifications to the document are for your convenience in querying the document, and not intended to be permanent.

In this case, you want to make an in-memory copy of the document, transform the in-memory copy, query it, and then close the document without serializing the modified document. This article describes the various approaches to working with documents in memory.

There is one important point to make about this method: you must supply a resizable memory stream to this method. You often have to create a resizable memory stream from a byte array, or you must create a resizable memory stream from a non-resizable memory stream.

Creating Resizable Memory Streams from Byte Arrays When working with the SharePoint Products and Technologies object models, you retrieve documents from a document library as a byte array, and there is a MemoryStream constructor that can create a memory stream from a byte array.

However, this constructor creates a non-resizable memory stream. Instead, you must create a MemoryStream object using a constructor that takes no arguments, and then write the byte array to the newly created memory stream.

The following example shows how to create a resizable memory stream from a byte array. IO; using DocumentFormat. Packaging; using DocumentFormat. ReadAllBytes "Test. Write byteArray, 0, int byteArray. IO Imports DocumentFormat. Packaging Imports DocumentFormat. Write byteArray, 0, CInt byteArray. CreateNew mem. It creates a memory stream from a byte array. To create a resizable memory stream, you create a MemoryStream object by using the constructor that takes no arguments, and then copy the non-resizable memory stream to the newly created memory stream.

The following example shows how to create a resizable memory stream from a non-resizable memory stream. Read buffer, 0, buffer. Length ; destination. Length destination. CreateNew memoryStream. It uses the technique of creating a resizable memory stream from a non-resizable memory stream, and then opening the document from the memory stream by using the Open XML SDK 2.

Making Temporary Modifications to In-Memory Copies of an Open XML Documents There are several circumstances where you want to make an in-memory copy of an Open XML document, make some temporary modifications to the in-memory copy, query the in-memory copy, and then close the document without making any modifications to the original document.

For example, before querying a document, you may want to first accept all tracked revisions in the document. Important Processing the contents of a document without first accepting tracked revisions is a very difficult programming task.

There are more than 40 elements and attributes that are used in WordprocessingML to track revisions, and some of these elements and attributes have fairly involved semantics.

By first accepting tracked revisions, you greatly simplify your programming tasks. However, you may not want to modify the original document. This section shows a simple approach that enables you to make an in-memory copy of a document, accept tracked revisions, and then query the document without modifying the original. The simplest way to accept tracked revisions is to read the document into a byte array, write the byte array to a resizable memory stream, accept tracked revisions for the document that is open in the memory stream, and then query the document per your requirements.

The following example shows using the RevisionAccepter class to accept revisions. IO; using System. Linq; using System. Linq; using DocumentFormat. Parse p. OuterXml ; Console. Open mem, True RevisionAccepter. Elements Of Paragraph. OuterXml Console. Insert a paragraph into the document, turn on revision tracking, and make revisions in the first paragraph. When I run this for the sample document that I created that included tracked revisions in the first paragraph , the example produces the following output.

A few simple techniques enable you to work with in-memory documents as easily as working with documents stored in file systems. There is lots of content there. This includes articles, how-to videos, and links to many blog posts.
