Returns a list of all the annotations in the store.
Overloads
| GetAnnotations() |
Returns a list of all the annotations in the store. |
| GetAnnotations(ContentLocator) |
Returns a list of annotations that have Anchors with locators that begin with a matching ContentLocatorPart sequence. |
Examples
The following example shows how to use the GetAnnotations method to determine whether there are any annotations contained in the store.
// ---------------------------- CloseFile -----------------------------
private void CloseFile()
{
// If there are existing annotations, then they should be saved.
if (_annStore.GetAnnotations().Count > 0)
{
string backupFile = _fileName + ".annotations" + ".xml";
FileStream backupStream = new FileStream(backupFile, FileMode.Create);
CopyStream(_annotationBuffer, backupStream);
_annStore.Flush();
_annServ.Disable();
}
}
GetAnnotations()
Returns a list of all the annotations in the store.

The list of all annotations that are currently in the store.
Exceptions
Dispose has been called on the store.
Examples
The following example shows how to use the GetAnnotations method to determine whether there are any annotations in the store.
// ---------------------------- CloseFile -----------------------------
private void CloseFile()
{
// If there are existing annotations, then they should be saved.
if (_annStore.GetAnnotations().Count > 0)
{
string backupFile = _fileName + ".annotations" + ".xml";
FileStream backupStream = new FileStream(backupFile, FileMode.Create);
CopyStream(_annotationBuffer, backupStream);
_annStore.Flush();
_annServ.Disable();
}
}
Remarks
The GetAnnotations method will never return null; however the list may be empty if the store contains no annotations.

GetAnnotations(ContentLocator)
Returns a list of annotations that have Anchors with locators that begin with a matching ContentLocatorPart sequence.
public:
override System::Collections::Generic::IList<System::Windows::Annotations::Annotation ^> ^ GetAnnotations(System::Windows::Annotations::ContentLocator ^ anchorLocator);public override System.Collections.Generic.IList<System.Windows.Annotations.Annotation> GetAnnotations (System.Windows.Annotations.ContentLocator anchorLocator);override this.GetAnnotations : System.Windows.Annotations.ContentLocator -> System.Collections.Generic.IList<System.Windows.Annotations.Annotation>Public Overrides Function GetAnnotations (anchorLocator As ContentLocator) As IList(Of Annotation)Parameters
- anchorLocator
- ContentLocator
The starting ContentLocatorPart sequence to return matching annotations for.
Returns
The list of annotations that have Anchors with locators that start and match the given anchorLocator; otherwise, null if no matching annotations were found.
Examples
The following example shows how to use the GetAnnotations method to determine whether there are any annotations in the store.
// ---------------------------- CloseFile -----------------------------
private void CloseFile()
{
// If there are existing annotations, then they should be saved.
if (_annStore.GetAnnotations().Count > 0)
{
string backupFile = _fileName + ".annotations" + ".xml";
FileStream backupStream = new FileStream(backupFile, FileMode.Create);
CopyStream(_annotationBuffer, backupStream);
_annStore.Flush();
_annServ.Disable();
}
}
Remarks
This GetAnnotations method internally uses the StartsWith method of the ContentLocator class to search and match for the annotations to return.
