7.4.2 Sample Code for .NET API

The following code is the sample code for operating multiple Shunsaku Files in one transaction using .NET API.

/*
 * This program assumes that the following variables have been declared
 *  sPerson :The information of employees to be added
 *  sQuery :Character string containing search expression
 *  sReturn :Character string containing return expression
 *  updateData :Character string containing update data
 */
// Create ShunService object
// Host name in the connection destination: DirSvr1
// Port number: 33101
// Shunsaku File name: fileA

ShunService service = new ShunService();
service.Host = "DirSvr1";
service.Port = 33101;
service.ShunsakuFile = "fileA";
service.Connect();

// Turn off auto-commit mode
service.AutoCommit = false;

ShunRecordCollection insertRecords = new ShunRecordCollection();
ShunRecord personRecord = new ShunRecord( sPerson );
insertRecords.Add( personRecord );

// Add data
service.Insert( insertRecords );

//Switch Shunsaku File in the connection destination to fileD
service.ChangeShunsakuFile("fileD");

ShunSearchRequirement req = new ShunSearchRequirement();
req.QueryExpression = sQuery;
req.ReturnExpression = sReturn;
// Search the update data
ShunResultSet rs = service.Search( req );
ShunRecord updateRecord = null;

  updateRecord = record;
}
updateRecord.Data = updateData;

ShunRecordCollection updateRecords = new ShunRecordCollection();
updateRecords.Add( updateRecord );

//Update data
service.Update( updateRecords );

// Commit the updates made so far
service.Commit();

service.Disconnect();
