10.3.3.2 Deleting Data by Specifying Record IDs

Use the Delete method to delete data.

The .NET APIs use record IDs to delete data. The record IDs of the data to be deleted have to be obtained before deleting the data.

The following diagram shows the process for deleting data by specifying a record ID.

[Figure 10-14 Flow of the Process for Deleting Data by Specifying a Record ID]

Sample Code for C# .NET

ShunService service = new ShunService();
service.Connect();

ShunRecordCollection recCol = new ShunRecordCollection();                        (1)
recCol.Add( record );                                                            (2)
service.Delete( recCol );                                                        (3)

service.Disconnect();

Sample Code for VB .NET

Dim service As New ShunService()
service.Connect()

Dim recCol As New ShunRecordCollection()                                         (1)
recCol.Add( record )                                                             (2)
service.Delete( recCol )                                                         (3)

service.Disconnect()

(1) Create a ShunRecordCollection Object

Create a ShunRecordCollection object.
