Exemples

L’exemple de code suivant crée un PropertyEnumerator, puis montre l’utilisation des MoveNext méthodes et Current pour déplacer la 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);  
            }  
        }  
    }  
}
