예
The following code sample uses the Contains method to determine if an enumerator with the name "For Each File Enumerator" is in the collection. The method returns a Boolean.
[!참고]
To use the following code sample with a locale other than English, change the string, "For Each File Enumerator", to the localized name of the enumerator.
using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Runtime.Enumerators.Item;
namespace ForEachEnums
{
class Program
{
static void Main(string[] args)
{
Application app = new Application();
ForEachEnumeratorInfos feInfos = app.ForEachEnumeratorInfos;
// Search the collection by name.
if (feInfos.Contains("For Each File Enumerator"))
Console.WriteLine("The collection contains {0} enumerator", feInfos[0].Name);
else
Console.WriteLine("The collection does not contain {0} enumerator", feInfos[0].Name);
}
}
}
Sample Output:
The collection contains For Each File Enumerator enumerator
