  1. If you are running your blog on WordPress.com, you just include the following lines before your code.

    [sourcecode language="csharp"]
    //your code comes here
    [/sourcecode]
    

    WordPress.com gives us the facility to avoid worrying about code highlighting. If your code is in between these blocks then it will automatically render as per the language you specified. It can support many languages.

    Some of them are..

    html

    javascript

    java

    javafx

    matlab (keywords only)

    objc

    perl

    php

    If you have a self-hosted site, or one hosted on wordpress.org, you should should use the SyntaxHighlighter plugin: wordpress.org/plugins/syntaxhighlighter.

    This is the plugin the WordPress team sourced to create this functionality on wordpress.com

  2. Sorry to say, but with following code you mentioned WONT WORK

    [sourcecode language="csharp"]
    //your code comes here
    [/sourcecode]
    

    So, on WordPress Site to add Code snippet to the wordpress blog is:

    [code language="javascript"]
    //your language script here
    [/code]
    

    Hope this helped you! 🙂

  3. Adding to SHEKHAR SHETE’s answer.

    For inline code blocks:

    Selecting a text and then performing Alt+Shift+x will make text like:

    THIS is an example
    

    This will actually sorround the text with <code></code>

    Writing text inside `..` is another way

    source

  4. Do this if you want to add code in your wordpress post:

    Switch to Text from HTML in your wordpress editor, then insert
    <code>
    as starting tag and
    </code>
    as end tag.

    This is the only method that works in the latest wordpress at the time I am writing the answer. Have fun!
