Check if file is being used before moving it

Question

I am playing a *.mp4 file in media player but at the same time trying to move the file from one place to another I need to check if the file is being accessed by another process i want to block the move process.

public Boolean fileInUse(FileInfo file)
{
    FileStream stream=null;
    try
    {
        stream = file.Open(FileMode.Open, FileAccess.Read, FileShare.None);

    }
    catch (IOException)
    {
        //File is in use
        Console.WriteLine("File is Being used");
        return true;
    }
    finally {
        if (stream != null) {
            stream.Close();
        }
    }
    Console.WriteLine("File is not in use");
    return false;    
}

public Boolean fileInUse(FileInfo file)
{
    bool fileInUse = false;
    FileStream stream = null;
    try
    {
        stream = file.Open(FileMode.Open, FileAccess.Read, FileShare.None);
        stream.Close();
    }
    catch (IOException)
    {
        //File is in use
        Console.WriteLine("File is Being used");
        fileInUse = true;
    }

    Console.WriteLine("File is not in use");
    return fileInUse;    
}
