Mongodb editing file information with c# driver

gistfile1.cs

//Easier to just pull the file collection and edit the files documents, just be careful, example:


public void SaveMetadata(string id, MetadataJson metadata)
{
  var gridFs = FilesContext.GetGridFs();
	var files = gridFs.Database.GetCollection(gridFs.Settings.FilesCollectionName);
	var file = files.FindOneById(new BsonObjectId(id));
	var metadataDocument = file["metadata"].AsBsonDocument;
	metadataDocument.Set("comment", metadata.comment ?? string.Empty);
	if (metadata.name.IsNotNullOrWhiteSpace())
	{
		file.Set("filename", metadata.name);
	}
	files.Save(file);
}

public class MetadataJson
{
  public string name { get; set; }
	public string comment { get; set; }
}
