Примеры
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);
}
}
}
}
