C# – Inserting newlines in Word using OpenXML

cms-wordopenxml

I am using openxml WordProcessingDocument to open a Word template and replace placeholder x1 with a string. This works fine unless I need the string to contain a newline.
How can I replace x1 with text may contain newlines that word would recognise? I have tried \n \r but these do not work

Just to explain further when the word template is opened I read it into a StreamReader then use .Replace to replace x1.

To insert newlines, you have to add a Break instance to the Run.

Example:

run.AppendChild(new Text("Hello"));
run.AppendChild(new Break());
run.AppendChild(new Text("world"));

The XML produced will be something like:

<w:r>
  <w:t>Hello</w:t>
  <w:br/>
  <w:t>world</w:t>
</w:r>

C# – Should ‘using’ directives be inside or outside the namespace

There is actually a (subtle) difference between the two. Imagine you have the following code in File1.cs:

// File1.cs
using System;
namespace Outer.Inner
{
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now imagine that someone adds another file (File2.cs) to the project that looks like this:

// File2.cs
namespace Outer
{
    class Math
    {
    }
}

The compiler searches Outer before looking at those using directives outside the namespace, so it finds Outer.Math instead of System.Math. Unfortunately (or perhaps fortunately?), Outer.Math has no PI member, so File1 is now broken.

This changes if you put the using inside your namespace declaration, as follows:

// File1b.cs
namespace Outer.Inner
{
    using System;
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now the compiler searches System before searching Outer, finds System.Math, and all is well.

Some would argue that Math might be a bad name for a user-defined class, since there's already one in System; the point here is just that there is a difference, and it affects the maintainability of your code.

It's also interesting to note what happens if Foo is in namespace Outer, rather than Outer.Inner. In that case, adding Outer.Math in File2 breaks File1 regardless of where the using goes. This implies that the compiler searches the innermost enclosing namespace before it looks at any using directive.

How to display code snippets in MS Word preserving format and syntax highlighting

Here is the best way, for me, to add code inside word:

Go to Insert tab, Text section, click Object button (it's on the right)
Choose OpenDocument Text which will open a new embedded word document
Copy and paste your code from Visual Studio / Eclipse inside this embedded word page
Save and close

Advantages

The result looks very nice. Here are the advantages of this method:

The code keeps its original layout and colors
The code is separated from the rest of the document, as if it was a picture or a chart
Spelling errors won't be highlighted in the code (this is cool !)

And it takes only few seconds.
