How to deal with a sealed class when I wanted to inherit and add properties

Question

In a recent question on Stack Overflow, I asked how I might parse through a file name to extra meta info about a file.

After I worked through that problem, I decided

Answer 1

You can easily wrap the file info properties in your own properties if you like.

public long Length
{
    get
    {
       return this.FileInfo.Length;
    }
}
