Error handling Leave feedback
On this page
All Convert() methods throw on failure. Use standard try/catch with specific exception types:
using GroupDocs.Markdown;
try
{
string md = MarkdownConverter.ToMarkdown("file.docx");
Console.WriteLine(md);
}
catch (DocumentProtectedException)
{
Console.WriteLine("Wrong or missing password.");
}
catch (InvalidFormatException)
{
Console.WriteLine("File is corrupt or unsupported.");
}
catch (GroupDocsMarkdownException ex)
{
Console.WriteLine($"Conversion failed: {ex.Message}");
}
| Exception | When thrown |
|---|---|
DocumentProtectedException | Document is password-protected and no password or wrong password was provided |
InvalidFormatException | File is corrupt or has an unrecognized format |
GroupDocsMarkdownException | General conversion error |
Non-fatal issues are reported via ConvertResult.Warnings:
using GroupDocs.Markdown;
using var converter = new MarkdownConverter("data.xlsx");
ConvertResult result = converter.Convert(new ConvertOptions { MaxRows = 10 });
Console.WriteLine(result.Content);
foreach (string warning in result.Warnings)
Console.WriteLine($"Warning: {warning}");
