Penerapan
Contoh
Contoh kode berikut menambahkan XMLTask ke paket, dan mengatur properti menggunakan TaskHost.
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.XMLTask;
namespace XMLTask_API
{
class Program
{
static void Main(string[] args)
{
// Set up the objects and tasks.
Package pkg = new Package();
Executable exec1 = pkg.Executables.Add("STOCK:XMLTask");
TaskHost th = exec1 as TaskHost;
// You can cast the InnerObject to the XmlTask here.
// XMLTask myTask = th.InnerObject as XMLTask;
// Create a variable and a FILE connection manager to books.xml.
Variable resultVar = pkg.Variables.Add("resultVariable", false, "", "Variable for the result");
ConnectionManager connMgr = pkg.Connections.Add("FILE");
connMgr.Name = "XMLConnectionManager";
// The file, Books.xml, is stored on the C:\ drive.
connMgr.ConnectionString = @"c:\books.xml";
// Set the XMLTask properties.
// The first property to set is the OperationType. Depending on the
// OperationType, different properties are valid.
// The operation type in this example is VALIDATE.
th.Properties["OperationType"].SetValue(th, DTSXMLOperation.Validate);
th.Properties["SourceType"].SetValue(th, DTSXMLSourceType.FileConnection);
th.Properties["Source"].SetValue(th, connMgr.Name);
th.Properties["OverwriteDestination"].SetValue(th, true);
th.Properties["SaveOperationResult"].SetValue(th, true);
th.Properties["DestinationType"].SetValue(th, DTSXMLSaveResultTo.Variable);
th.Properties["Destination"].SetValue(th, resultVar.Name);
th.Properties["SecondOperandType"].SetValue(th, DTSXMLSourceType.DirectInput);
th.Properties["SecondOperand"].SetValue(th, "<x></x>");
th.Properties["ValidationType"].SetValue(th, DTSXMLValidationType.DTD);
th.Properties["FailOnValidationFaile"].SetValue(th, true);
DTSExecResult valResults = pkg.Validate(pkg.Connections, pkg.Variables, null, null);
Console.WriteLine("RESULTS: {0}", valResults);
}
}
}
Contoh Output:
RESULTS: Success
