How to remove all Meta keyword tags? -Jpeg Metadata Adapter

I am using jpeg metadata utility in c#. I want to remove the old keyword tags and add new tags. When I used metaAdapter.Metadata.Keywords.Add(“”) it overwrites with existing keywords. But I want to clear the existing keywords. Finally I used clear function () before adding keyword.

Example:

_{JpegMetadataAdapter metaAdapter = new JpegMetadataAdapter(filePath);}

_{metaAdapter.Metadata.Title = "Bus picture";}

_{metaAdapter.Metadata.Subject = "New modern bus";}

_{metaAdapter.Metadata.Keywords.Clear();}

_{metaAdapter.Metadata.Keywords.Add("transport");}

_{bool saved = metaAdapter.Save();}
