Reading WMV file metadata is quite simple when we using the WindowsMediaPlayerClass.

I have given the Steps below. here in this sample code i have stored the metadata
in a datagridview.

1. Open a Window Application project in .NET 2.0

2. Add Windows Media Player (WMP.dll) component reference to the project

3. Place a datagridview control in the form

4. Add a button the form.

5. Copy the below code snippets and paste it in the button click event


WMPLib.WindowsMediaPlayerClass mediaPlayer = new WMPLib.WindowsMediaPlayerClass();
WMPLib.IWMPMedia mediaItem = mediaPlayer.add(@"D:\samplefile.wmv");


DataTable dtc = new DataTable();
DataRow drc;
dtc.Columns.Add(new DataColumn("Property", typeof(string)));
dtc.Columns.Add(new DataColumn("Value", typeof(string)));

for (Int32 attrIndex = 0; attrIndex < mediaItem.attributeCount; attrIndex++)
{
drc = dtc.NewRow();
drc[0] = mediaItem.getAttributeName(attrIndex);
drc[1] = mediaItem.getItemInfo(mediaItem.getAttributeName(a ttrIndex));
dtc.Rows.Add(drc);
}
DataView dvc = new DataView(dtc);
dataGridView1.DataSource = dvc;
