public:
 bool Contains(System::Object ^ index);

public bool Contains (object index);

member this.Contains : obj -> bool

Public Function Contains (index As Object) As Boolean

Parameter

index

Object

Nama, identitas, atau indeks DtsProperty objek.

Nilai false menunjukkan bahwa pengindeksan tidak dapat digunakan untuk mengambil item dari DtsProperties koleksi.

Contoh

Sampel kode berikut menggunakan Contains metode untuk melihat apakah salah satu properti dalam koleksi adalah "CertificateObject".

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
