- Object

屬性值
DtsProperty 物件。
範例
下列程式碼範例會使用 DtsProperties[x] 語法來抓取集合中第五個物件的名稱，以從集合中抓取專案。
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 pkg As Package = New Package()

Dim myEnumerator As PropertyEnumerator = pkgProperties.GetEnumerator()

Dim containsCertObj As Boolean = pkgProperties.Contains("CertificateObject")

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
End Namespace

備註
如果方法的呼叫傳回 Contains true ，您可以使用語法來存取集合中的指定專案 DtsProperties[index] 。 如果 Contains 方法傳回 false ，則這個屬性會擲回例外狀況。 在 C# 中，這個屬性是 DtsProperties 類別的索引子。
