Hello, all.

I am messing around with the WMPLib component provided by Windows Media Player 12 (wmp.dll) in VB.NET with .NET Framework 3.5 SP1.

I am trying to retrieve a media item from my media library based on its name (assuming there are no duplicate names). At the moment, I'm grabbing the entire media library, and looping through every media item, and quitting the loop when I've found the correct media item. This works well (except for when a media item with that name cannot be found), but I was hoping there was a more efficient way of doing this.

Here is my code so far:

Public Class WMPTest
    Private myWMP As WMPLib.IWMPCore
    Private myMediaCollection As WMPLib.IWMPMediaCollection
    Private myTrack As WMPLib.IWMPMedia
    Private allTracks As WMPLib.IWMPPlaylist

    Public Sub New()
        ' This call is required by the Windows Form Designer.
        InitializeComponent()

        ' Add any initialization after the InitializeComponent() call.
        myWMP = New WMPLib.WindowsMediaPlayer
        myMediaCollection = myWMP.mediaCollection
        allTracks = myMediaCollection.getAll

        Dim theTrack As WMPLib.IWMPMedia = findTrack("Yellow Submarine")
        MessageBox.Show(theTrack.name)
    End Sub

    Public Function findTrack(ByVal strTrackName As String) As WMPLib.IWMPMedia
        For i As Integer = 0 To (allTracks.count - 1)
            If allTracks.Item(i).name = strTrackName Then
                myTrack = allTracks.Item(i)
                Exit For
            End If
        Next
        'myTrack is now the track that we wanted to retrieve
        Return myTrack
    End Function
End Class

So what I really want is a way to optimize findTrack() to do its thing without looping through the entire media library (which could be huge). Anyone have a clue?
