C # class for operating LRC lyrics files

I wrote it for one day and completed the class for C # To operate the lyrics. There are explanations in the specific usage, but they are not perfect because there is no perfect thing. If you feel betterLeave a message for me.! Thank you very much. I am not a newbie ....

 

 

The class of the lyrics. I have not changed the namespace.
