MimePartCollection.Contains(MimePart) 方法

定义

命名空间:

System.Web.Services.Description

程序集:

System.Web.Services.dll

返回一个值，该值指示指定的 MimePart 是否是 MimePartCollection 的成员。

public:
 bool Contains(System::Web::Services::Description::MimePart ^ mimePart);

public bool Contains (System.Web.Services.Description.MimePart mimePart);

member this.Contains : System.Web.Services.Description.MimePart -> bool

Public Function Contains (mimePart As MimePart) As Boolean

参数

mimePart

MimePart

要检查其集合成员资格的 MimePart。

返回

Boolean

如果 mimePart 参数是 MimePartCollection 的成员，则为 true；否则为 false。

示例

以下示例演示了该方法的典型用法 Contains 。

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 successfully added at position: {0}", myMimePartCollection->IndexOf( myMimePart2 ) );

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 successfully added at position: "
                        +myMimePartCollection.IndexOf(myMimePart2));
}

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 successfully added at position: " + _
                  myMimePartCollection.IndexOf(myMimePart2).ToString())
End If
