    Public Overloads Function OpenRead( _
       ByVal events As FileSystemEvents, _
       ByVal userData As Object, _
       ByVal share As FileShare, _
       ByVal representationType As RepresentationType _

    'Usage
     
    
    Dim instance As FtpFile
    Dim events As FileSystemEvents
    Dim userData As Object
    Dim share As FileShare
    Dim representationType As RepresentationType
    Dim value As Stream
     
    value = instance.OpenRead(events, userData, share, representationType)

    Parameters

    events
    A Xceed.FileSystem.FileSystemEvents object that will be used to raise events. Cannot be NULL.
    userData
    Opaque data that will be passed back to the event handler when an event is raised.
    share
    A System.IO.FileShare constant that determines how the file will be shared by different processes.
    representationType
    A RepresentationType value indicating how the data is transferred from the FTP server.

    Return Value

    A System.IO.Stream object that can be used to read data from the file.
    Remarks

    The returned stream is guaranteed to be readable, but is not seekable.

    Since the stream returned by the OpenRead method is not seekable (meaning that neither the length or position can be retrieved), data can be read by either looping through the stream until the end of the stream has been reached, or a StreamReader can be created around the stream to read the data.
