Check if a file is locked in Windows

Here is a simple code to check if a file is locked if it exists. If the file does not exist, it checks whether the file can be created

public static bool IsFileLocked(FileInfo file)
{
	try
    {
    	using FileStream stream = file.Open(FileMode.OpenOrCreate, FileAccess.Read, FileShare.None);
        stream.Close();
    }
    catch (IOException)
    {
        return true;
    }

    return false;
}

It also very useful to know what process is locking the file, so here is another piece of code that is able to get this process name: https://stackoverflow.com/a/20623302/987949
