Timespan to int total seconds

Help please friends.
In the post @Default117 resolve the cuestion, but i need convert the resul to int, the post is:
In this post the result of a time difference is obtained using a Timespan of the last time the time was saved when leaving and the start of the game, the result is a time in Timespan, I need to convert that result of the time difference in the number of total seconds in int.
How can I make that conversion?

TimeSpan has a property of TotalSeconds. TotalSeconds is expressed as a double, just round this up/down to an integer.
