What this adds

Seven example projects. The first six are the README's "... in C#" tasks that had no example of their own; OcrPdf goes with the OCR section that #94 added.

Project	What it shows	Sample
ConvertDocxToPdf	Word to PDF	test.docx
ConvertHtmlToPdf	an HTML file, and an HTML string such as an invoice, to PDF files (a web page by URL stays in ConvertUrlToPdf)	test.html
ConvertExcelToPdf	Excel to PDF	test.xlsx
ExtractTextFromPdf	the text of a PDF into a string	test.pdf
CompressPdf	compression with Preset=web, printing the size before and after	test.pdf
ConvertHtmlToDocx	HTML to an editable Word document	test.html
OcrPdf	a scanned PDF made searchable	scanned.pdf (new)

They follow the existing examples and Examples/README.md: a .NET 10 console project that references the library source, reads the token from CONVERTAPI_TOKEN, finds its sample through AppContext.BaseDirectory, saves the result in the temp folder, catches ConvertApiException and prints Status Code: and Response:, and waits for Enter.

• Each has at most 3 comment lines at the top.
• Each is in ConvertApi.sln under the Examples folder, so build compiles it and the Examples workflow runs it. The 49 solution lines were added by hand: dotnet sln add would also have rewritten every existing project with x64 and x86 platforms.
• Each is linked from the Tasks table, from its README section ("Example project: ...") and from the More examples list, which keeps its heading and its order.
• Examples/TestFiles/scanned.pdf is a made-up letter (fictional companies, an example.com address) rendered to a 150 dpi grayscale JPEG and wrapped in a one-page A4 PDF, with no text layer and no document metadata: 113 KB. The default OCR settings read all of it.
• No existing example is renamed or removed.

How it was checked

• Release build of ConvertApi.sln: 0 errors. The only warnings are the 3 that ConverterCatalogDemo and GetConverterInfoDemo already had.
• .github/ci/check_csharp.py examples with .github/ci/ci-host.targets, as the Examples workflow runs it, but against the staging API (CONVERTAPI_BASE_URI=https://stag-v2.convertapi.com): 7 of 7 passed, and CiHost deleted every uploaded and result file.

Example	Result on staging
CompressPdf	compressed.pdf, 246,542 bytes: 23% of test.pdf's 1,086,060
ConvertDocxToPdf	word-to-pdf.pdf, 146,734 bytes
ConvertExcelToPdf	excel-to-pdf.pdf, 43,891 bytes
ConvertHtmlToDocx	html-to-word.docx, 13,241 bytes
ConvertHtmlToPdf	html-file.pdf, 21,994 bytes, and html-string.pdf, 12,791 bytes
ExtractTextFromPdf	printed the 2,485 characters of text
OcrPdf	searchable.pdf, 139,419 bytes, with the letter's text as its text layer

In the Examples workflow, which runs against the production API, these add 8 conversions per job (ConvertHtmlToPdf converts twice).

Not changed: the library, the existing examples, build.yml, the CI files, CHANGELOG.md and RELEASING.md.

What changed in this PR

Adds seven runnable examples for the README’s C# conversion tasks, including the OCR documentation introduced in #94. The examples use the library source and follow the existing console-project structure.

Changes:

• Demonstrates Word, Excel and HTML conversions, PDF text extraction, compression and OCR.
• Adds .NET 10 projects with sample-file copying and solution registration.
• Links the examples from the README’s task table, relevant sections and examples list.
