매개 변수
- index
유형: System.Object
The name, ID, or index of the DtsEventHandler object to return from the collection.
속성 값
유형: Microsoft.SqlServer.Dts.Runtime.DtsEventHandler
A DtsEventHandler object from the collection.
주의
If the call to the Contains method returns true, you can access the specified element in the collection by using the syntax DtsEventHandlers[index]. If the Contains method returns false, this property throws an exception. In C#, this property is the indexer for the DtsEventHandlers class.
예
The following code example retrieves the DtsEventHandlers collection, then uses Contains to see if the item syntax [x] can be used on the collection.

using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
namespace Microsoft.SqlServer.SSIS.Samples
{
class Program
{
static void Main(string[] args)
{
Package pkg = new Package();
// Set up a DtsEventHandler for the OnError event of the package.
DtsEventHandler dtsEHOE = (DtsEventHandler)pkg.EventHandlers.Add("OnError");
DtsEventHandler dtsEHW = (DtsEventHandler)pkg.EventHandlers.Add("OnWarning");
// Create the DtsEventHandlers collection.
DtsEventHandlers dtsEHColls = pkg.EventHandlers;
// Use the Contains method to see if the item[x] syntax can be used.
Boolean dtsContains = dtsEHColls.Contains(0);
Console.WriteLine("Item syntax can be used? {0}", dtsContains);
//Using the Item method syntax of [x], obtain the first entry and a name.
DtsEventHandler dtsEHFirstEntry = dtsEHColls[0];
String nameOfFirstItem = dtsEHColls[0].Name;
//Print the name of the log provider object located at position [0].
Console.WriteLine("The ID of the first event handler is: {0}", dtsEHFirstEntry.ID);
Console.WriteLine("The Name of the first event handler is: {0}", nameOfFirstItem);
}

The ID of the first event handler is: {4B9E438E-BA17-4A51-8235-3072AFF92F99}
The Name of the first event handler is: OnError
