Beispiel

Das folgende Beispiel veranschaulicht eine typische Verwendung der Contains-Methode.

Dim myMimePart2 As New MimePart()
Dim myMimeXmlBinding2 As New MimeXmlBinding()
myMimeXmlBinding2.Part = "body"
myMimePart2.Extensions.Add(myMimeXmlBinding2)
' Add a mimepart to the mimepartcollection.
myMimePartCollection.Add(myMimePart2)
Console.WriteLine("Adding a mimepart object...")
' Check if collection contains added mimepart object.
If myMimePartCollection.Contains(myMimePart2) Then
   Console.WriteLine("'MimePart' is succesfully added at position: " + _
                  myMimePartCollection.IndexOf(myMimePart2).ToString())
End If

MimePart myMimePart2=new MimePart();
MimeXmlBinding myMimeXmlBinding2 = new MimeXmlBinding();
myMimeXmlBinding2.Part = "body";
myMimePart2.Extensions.Add(myMimeXmlBinding2);
// Add a mimepart to the mimepartcollection.
myMimePartCollection.Add(myMimePart2);      
Console.WriteLine("Adding a mimepart object...");
// Check if collection contains added mimepart object.
if(myMimePartCollection.Contains(myMimePart2))
{
   Console.WriteLine("'MimePart' is succesfully added at position: "
                        +myMimePartCollection.IndexOf(myMimePart2));
}

MimePart^ myMimePart2 = gcnew MimePart;
MimeXmlBinding^ myMimeXmlBinding2 = gcnew MimeXmlBinding;
myMimeXmlBinding2->Part = "body";
myMimePart2->Extensions->Add( myMimeXmlBinding2 );

// Add a mimepart to the mimepartcollection.
myMimePartCollection->Add( myMimePart2 );
Console::WriteLine( "Adding a mimepart object..." );

// Check if collection contains added mimepart object.
if ( myMimePartCollection->Contains( myMimePart2 ) )
   Console::WriteLine( "'MimePart' is succesfully added at position: {0}", myMimePartCollection->IndexOf( myMimePart2 ) );

MimePart myMimePart2 = new MimePart();
MimeXmlBinding myMimeXmlBinding2 = new MimeXmlBinding();
myMimeXmlBinding2.set_Part("body");
myMimePart2.get_Extensions().Add(myMimeXmlBinding2);

// Add a mimepart to the mimepartcollection.
myMimePartCollection.Add(myMimePart2);
Console.WriteLine("Adding a mimepart object...");

// Check if collection contains added mimepart object.
if (myMimePartCollection.Contains(myMimePart2)) {
    Console.WriteLine("'MimePart' is succesfully added at position: "
        + myMimePartCollection.IndexOf(myMimePart2));
