This code is a C# program that uses the Markdig library to parse a markdown file named TestMarkDown.md
and extract its headers. Here's a breakdown of what the code does:
- The program starts by reading the contents of the
TestMarkDown.md
file into a string variable namedmarkdown
. - The
markdown
string is then processed to replace all occurrences of the\r\n
newline sequence with the newline sequence used by the current environment, as determined by theEnvironment.NewLine
property. - A new
MarkdownPipeline
object is created using theMarkdownPipelineBuilder
class and itsBuild
method. This pipeline object is used to configure how the markdown text will be parsed. - The
Markdown.Parse
method is called to parse themarkdown
string using the specified pipeline. The result is aMarkdownDocument
object that represents the structure of the markdown text. - The
Descendants<HeadingBlock>
method is called on thedocument
object to get an enumerable collection of all heading blocks in the document. - The program then enters a loop that iterates over each heading block in the collection.
- For each heading block, the first inline element is extracted using the
FirstOrDefault
method. - If the inline element is of type
LiteralInline
, its content is written to the console using theConsole.WriteLine
method.
In summary, this code reads a markdown file, parses it, and extracts and prints its headers to the console.
