Get document info
GroupDocs.Metadata allows users to get meta information of a document which includes:
- File format (detected by the internal structure)
- File extension
- MIME type
- Number of pages
- File size
- A value indicating whether a file is encrypted
The following code sample demonstrates how to extract basic format information from a file.
BasicUsage.GetDocumentInfo
// Constants.InputXlsx is an absolute or relative path to your document. Ex: @"C:\Docs\source.xlsx"
using (Metadata metadata = new Metadata(Constants.InputXlsx))
{
if (metadata.FileFormat != FileFormat.Unknown)
{
IDocumentInfo info = metadata.GetDocumentInfo();
Console.WriteLine("File format: {0}", info.FileType.FileFormat);
Console.WriteLine("File extension: {0}", info.FileType.Extension);
Console.WriteLine("MIME Type: {0}", info.FileType.MimeType);
Console.WriteLine("Number of pages: {0}", info.PageCount);
Console.WriteLine("Document size: {0} bytes", info.Size);
Console.WriteLine("Is document encrypted: {0}", info.IsEncrypted);
}
}
