Contains メソッド

DtsProperty オブジェクトの名前、ID、またはインデックスを使用してコレクション内の項目にアクセスできるかどうかを示す Boolean を返します。

名前空間:  Microsoft.SqlServer.Dts.Runtime
アセンブリ:  Microsoft.SqlServer.ManagedDTS (Microsoft.SqlServer.ManagedDTS.dll)

構文

'宣言
Public Function Contains ( _
    index As Object _
) As Boolean
'使用
Dim instance As DtsProperties
Dim index As Object
Dim returnValue As Boolean

returnValue = instance.Contains(index)

public bool Contains(
    Object index
)

public:
bool Contains(
    Object^ index
)

member Contains : 
        index:Object -> bool 

public function Contains(
    index : Object
) : boolean

パラメーター

戻り値

型: System. . :: . .Boolean
名前、ID、またはインデックスを使用してコレクションにアクセスできるかどうかを示す Boolean です。値が true の場合は、DtsProperties[index] 構文を使用してコレクションにアクセスできます。
値が false の場合は、インデックスを使用して DtsProperties コレクションから項目を取得することができません。

使用例

次のコード サンプルでは、Contains メソッドを使用して、コレクション内のプロパティに "CertificateObject" が含まれるかどうかを確認します。

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);
            }
        }
    }
}

Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace DtsProperties_API
    Class Program
        Shared  Sub Main(ByVal args() As String)
            Dim pkg As Package =  New Package() 
 
            ' Get the Properties collection from the package.
            ' This shows the default properties set on new packages.
            Dim pkgProperties As DtsProperties =  pkg.Properties 
 
           ' Create the enumerator.
            Dim myEnumerator As PropertyEnumerator =  pkgProperties.GetEnumerator() 
 
            ' Show the use of the Contains method.
            Dim containsCertObj As Boolean =  pkgProperties.Contains("CertificateObject") 
            Console.WriteLine("Contains CertificateObject? {0}", containsCertObj)
 
            ' Show the use of the item[x] syntax.
            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
