範例

The following code sample creates a PropertyEnumerator, then shows the use of the MoveNext and Current methods to move over the collection.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

namespace DtsProperties_API
{
    class Program
    {
        static void Main(string[] args)
        {
            Package pkg = new Package();

            // Get the Properties collection from the package.
            // This shows the default properties set on new packages.
            DtsProperties pkgProperties = pkg.Properties;

           // Create the enumerator.
            PropertyEnumerator myEnumerator = pkgProperties.GetEnumerator();

            // Show the use of the Contains method.
            Boolean containsCertObj = pkgProperties.Contains("CertificateObject");
            Console.WriteLine("Contains CertificateObject? {0}", containsCertObj);

            // Show the use of the item[x] syntax.
            String aName = pkgProperties[5].Name;
            Console.WriteLine("Property 5 is {0}", aName);

            // Show the use of the MoveNext and Current methods.
            int i = 0;
            while ((myEnumerator.MoveNext()) && (myEnumerator.Current != null))
            {
                Console.WriteLine("[{0}] {1}", i++, myEnumerator.Current.Name);
            }
        }
    }
}

            Dim aName As String =  pkgProperties(5).Name 
            Console.WriteLine("Property 5 is {0}", aName)
 
            ' Show the use of the MoveNext and Current methods.
            Dim i As Integer =  0 
            While (myEnumerator.MoveNext()) &&(myEnumerator.Current <> Nothing)
                Console.WriteLine("[{0}] {1}",i = Console.WriteLine("[{0}] {1}",i + 1
            End While
        End Sub
    End Class
