Sample Code

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

ShunRecord record1 = new ShunRecord();
ShunRecord record2 = new ShunRecord();
ShunRecord record3 = new ShunRecord();
record1.Key = "20061101,00000001";                                       (1)
record2.Key = "20061101,00000002";                                       (1)
record3.Key = "20061101,00000003";                                       (1)
record1.Data = updateData1;                                              (2)
record2.Data = updateData2;                                              (2)
record3.Data = updateData3;                                              (2)

ShunKeyRequirement keyReq = new ShunKeyRequirement();                    (3)
keyReq.KeyName = "key1";                                                 (4)
keyReq.SearchType = ShunKeySearchType.CompleteMatch;                     (4)
keyReq.Records.Add( record1 );                                           (4)
keyReq.Records.Add( record2 );                                           (4)
keyReq.Records.Add( record3 );                                           (4)

service.UpdateByKey( keyReq );                                           (5)

service.Disconnect();

(1) Set the Direct Access Key

Set the direct access key at the ShunRecord object.

(2) Set the Data to be Updated

Set the data to be updated at the ShunRecord object.

(3) Create a ShunKeyRequirement Object

Create a ShunKeyRequirement object.

(4) Set to the ShunKeyRequirement Object

Set the direct access key name and the ShunRecord object to the ShunKeyRequirement object.

Specifying multiple ShunRecord objects with the add method to update multiple XML documents at a time.

(5) Execute the Update

Specify the ShunKeyRequirement object to the UpdateByKey method and execute the update.
