Class Geodatabase
Represents a mobile geodatabase containing geographic data and non-spatial tables.
Inheritance
Namespace: Esri.ArcGISRuntime.Data
Assembly: Esri.ArcGISRuntime.dll
Syntax
public sealed class GeodatabaseRemarks
Geodatabase is used to open and access the contents of a mobile geodatabase (.geodatabase file) that can contain geographic features, non-spatial tabular data, and data such as attachments, utility networks, field domain definitions, contingent values, and relationships between layers/tables.
Geodatabases can contain one or more geodatabase feature tables. You can create a layer from GeodatabaseFeatureTable tables, as follows:
-
A FeatureLayer from any table returned by GeodatabaseFeatureTables that contains point,
polyline, or polygon features. Check that HasGeometry is
true. - An AnnotationLayer from any table returned by GeodatabaseAnnotationTables.
- A DimensionLayer from any table returned by GeodatabaseDimensionTables.
You can generate a mobile geodatabase file from an ArcGIS feature service and downloaded it to a device using offline workflows offered by the GeodatabaseSyncTask and the OfflineMapTask. Apps can then operate offline to view and edit the features in these geodatabases. If the geodatabases are enabled for synchronization with the original feature service, edits can be synchronized when connectivity is restored.
Mobile geodatabase files can also be created with ArcGIS Pro. These geodatabases can be used offline but they do not support synchronization with the original feature service. See Build offline applications for more information.
For editing workflows that use a mobile geodatabase, you can use geodatabase transactions to manage a set of edits (transaction). If you start a transaction with BeginTransaction(), you can control when edits are committed (saved) as a single unit using CommitTransaction(). If you decide to discard the edits you can use RollbackTransaction(). If the app unexpectedly disconnects from the geodatabase, any active transaction will be rolled back. If the app crashes, or the user closes the app without saving edits, the transaction will be rolled back and the edits discarded.
