示例

// Check to see whether the collection contains mySecondSoapHeader.
if ( mySoapHeaderCollection->Contains( mySecondSoapHeader ) )
{
   // Get the index of mySecondSoapHeader from the collection.
   Console::WriteLine( "Index of mySecondSoapHeader: {0}", mySoapHeaderCollection->IndexOf( mySecondSoapHeader ) );

   // Get the SoapHeader from the collection.
   MySoapHeader^ mySoapHeader1 = dynamic_cast<MySoapHeader^>(mySoapHeaderCollection[ mySoapHeaderCollection->IndexOf( mySecondSoapHeader ) ]);
   Console::WriteLine( "SoapHeader retrieved from the collection: {0}", mySoapHeader1 );

   // Remove a SoapHeader from the collection.
   mySoapHeaderCollection->Remove( mySoapHeader1 );
   Console::WriteLine( "Number of items after removal: {0}", mySoapHeaderCollection->Count );
}
else
      Console::WriteLine( "mySoapHeaderCollection does not contain mySecondSoapHeader." );

// Check to see whether the collection contains mySecondSoapHeader.
if(mySoapHeaderCollection.Contains(mySecondSoapHeader))
{
    // Get the index of mySecondSoapHeader from the collection.
    Console.WriteLine("Index of mySecondSoapHeader: " +
        mySoapHeaderCollection.IndexOf(mySecondSoapHeader));

    // Get the SoapHeader from the collection.

        mySoapHeaderCollection.Count);
