ArcGIS.Core.Data.PluginDatastore Namespace : PluginField Class
Represents a column in a plug-in table or feature class.
Syntax
public sealed class PluginField 
Public NotInheritable Class PluginField 
Remarks
A plug-in table does not necessarily correspond to a database table on the back end. It can be any data structure or format, but it is presented to ArcGIS as a table. Similarly, the third-party data structure exposed through the Plugin Datasource does not necessarily contains fields, but they are exposed to ArcGIS in this fashion.
