using (Annotator annotator = new Annotator("result.bmp"))
{
var tmp = annotator.Get();
annotator.Remove(tmp[0]);
annotator.Save("removed.bmp");
}
// 3- How to remove some annotations from document using list of ID’s
using (Annotator annotator = new Annotator("result.bmp"))
{
var idList = new List{1, 2, 3};
annotator.Remove(idList);
annotator.Save("removed.bmp");
}
// 4- How to remove some annotations from document using list of annotations
using (Annotator annotator = new Annotator("result.bmp"))
{
var tmp = annotator.Get();
annotator.Remove(tmp);
annotator.Save("removed.bmp");
}

//assuming we are going to change some properties of existing annotation
AreaAnnotation updated = new AreaAnnotation
{
// It's important to set existed annotation Id
Id = 1,
BackgroundColor = 255,

Message = "This is updated annotation",
Replies = new List
{
new Reply
{
Comment = "Updated first comment",
RepliedOn = DateTime.Now
},
new Reply
{
Comment = "Updated second comment",
RepliedOn = DateTime.Now
}
}
};
// update annotation
annotator.Update(updated);
annotator.Save("result.bmp");
}
GroupDocs.Annotation makes it easy for Net developers to annotate documents and extract annotation information from XLSX files within any Net-based application by implementing a few easy steps.

{
List annotations = annotator.Get();
XmlSerializer formatter = new XmlSerializer(typeof(List));
using (FileStream fs = new FileStream("annotations.xml", FileMode.Create))

XLSX is well-known format for Microsoft Excel documents that was introduced by Microsoft with the release of Microsoft Office 2007. Based on structure organized according to the Open Packaging Conventions as outlined in Part 2 of the OOXML standard ECMA-376, the new format is a zip package that contains a number of XML files. The underlying structure and files can be examined by simply unzipping the .xlsx file.
