public int StreamNumber { get; set; }
Public Property StreamNumber As Integer
The stream number
Stream numbers range from 1 through 63. The stream number is different from the index. Stream indexes are zero-based, while each stream in the profile might have its own number, which is different from the index. If a new stream number is set, call the WMProfile.ReconfigStream method to have the new number to take effect. For more information, refer to the Microsoft documentation for IWMStreamConfig.GetStreamNumber.
