Markdown Code Block in C#

How to Create Markdown Inline Code or Code Block in C#

Aspose.HTML for .NET library is a stand-alone solution that allows you to parse and manipulate Markdown files without using other software. You can create a Markdown document from scratch, open from a local file and manipulate by inserting new elements, removing, or editing the content of existing nodes.
Use the Aspose.Html.Toolkit.Markdown.Syntax and Aspose.Html.Toolkit.Markdown.Parser namespaces to provide full Markdown parsing and MD syntax tree management based on the GitHub Flavored Markdown (GFM) specification.

How to Add Markdown Inline Code in C#

Using the C# library, you can programmatically edit MD files – change the document structure and content. Creating a Markdown inline code or Markdown code block in C# has a feature, that the CodeSpan or FencedCodeBlock element needs to be assembled from several nodes, such as text nodes, spaces between text nodes, or an empty line after the node.
Let’s look at creating a Markdown document from scratch and adding inline code to it.

    // Create the MarkdownSyntaxTree
    var markdown = new MarkdownSyntaxTree(new Configuration());

    // Use the SyntaxFactory property to get the factory for creating the Markdown syntax tree
    var mdf = markdown.SyntaxFactory;

    // Create an empty codeSpan node
    var codeSpan = mdf.CodeSpan();

    // Create text content for the codeSpan
    codeSpan.AppendChild(mdf.Text("Source code text"));

    // Add codeSpan to MD document
    markdown.AppendChild(codeSpan);

    // Add a space after the code node through a special WhiteSpace node
    markdown.AppendChild(mdf.Whitespace());

    // Prepare a path for MD file saving 
    string savePath = Path.Combine(OutputDir, "markdown-code.md");

    // Save MD file
    markdown.Save(savePath);

Steps to Create Markdown Code in C#

We remind you that the inline code needs to be assembled from the component nodes. Consider simple steps to create Markdown inline code:

1. Create a new empty CodeSpan node using CodeSpan() constructor in SyntaxFactory.
2. Use the Text() constructor to create text nodes for the CodeSpan.
3. Call the AppendChild() method of the MarkdownSyntaxNode class to add text nodes into the CodeSpan element.
4. Add created code block to the document syntax tree using AppendChild() method.
5. Use the Whitespace() constructor to create space after inline code.

Add Markdown Code Block in C#

The following C# code example shows how to add Markdown code block to MD document:

    // Create the MarkdownSyntaxTree
    var markdown = new MarkdownSyntaxTree(new Configuration());

    // Create a Markdown syntax factory
    var mdf = markdown.SyntaxFactory;

    // Create a start token and an end token that will frame a code block
    var startToken = mdf.Token(SourceText.From("```\r\n"));
    var endToken = mdf.Token(SourceText.From("\r\n```"));

    // Create a fenced code element
    var fencedCodeSpan = mdf.FencedCodeBlock(startToken, null, endToken);

    // Create text content for the fenced code element
    fencedCodeSpan.AppendChild(mdf.Text("Source code text"));

    //Add the fenced code element to MD file
    markdown.AppendChild(fencedCodeSpan);
            
    // Prepare a path for MD file saving 
    string savePath = Path.Combine(OutputDir, "markdown-code-block.md");

    // Save MD file
    markdown.Save(savePath);
