ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Desktop.Mapping Namespace / MapMember Class / GetUseSourceMetadata Method
Example Version

GetUseSourceMetadata Method (MapMember)
Gets whether or not the MapMember stores its own metadata or uses metadata retrieved from its source. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
public virtual bool GetUseSourceMetadata()

Return Value

True if the MapMember is using source metadata. False if it is using its own metadata
Exceptions
ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Remarks
Group layer ignores GetUseSourceMetadata. Sub layer types do not support metadata. They typically have a single source, specified on the parent layer, that controls the metadata.
Example
Layer Metadata
MapMember mapMember = map.GetLayersAsFlattenedList().FirstOrDefault(); //Search for only layers/tables here if needed.
if (mapMember == null) return;

//Gets whether or not the MapMember stores its own metadata or uses metadata retrieved
//from its source. This method must be called on the MCT. Use QueuedTask.Run
bool doesUseSourceMetadata = mapMember.GetUseSourceMetadata();

//Sets whether or not the MapMember will use its own metadata or the metadata from
//its underyling source (if it has one). This method must be called on the MCT.
//Use QueuedTask.Run
mapMember.SetUseSourceMetadata(true);

//Does the MapMember supports metadata
var supportsMetadata = mapMember.SupportsMetadata;

//Get MapMember metadata
var metadatstring = mapMember.GetMetadata();
//TODO:Make edits to metadata using the retrieved mapMetadata string.

//Set the modified metadata back to the mapmember (layer, table..)
if (mapMember.GetCanEditMetadata())
  mapMember.SetMetadata(metadatstring);
