ReaderClose Method (IMFReader)
Closes a file source.

Here is an example of how to close a file source:

m_objPreview = new MFPreviewClass();
//Configure preview
m_objPreview.PreviewWindowSet("", panelPreview.Handle.ToInt32());
m_objPreview.PreviewEnable("", 1, 1);
m_objMFReader = new MFReaderClass();
m_objMFReader.ReaderOpen(sourceFileName, "");
m_avProps = new M_AV_PROPS(); // set video format for conversion
m_avProps.vidProps.eVideoFormat = eMVideoFormat.eMVF_HD1080_5994i;
MFFrame pFrame = null;
// Get next frame or frame by position
if (m_objMFReader != null)
    m_objMFReader.SourceFrameConvertedGetByTime(ref m_avProps, -1, -1, out pFrame, "");
m_objPreview.ReceiverFramePut(pFrame, -1, ""); // show the frame on preview
// Close a source
