unbound datagridview send the data to a sql table

Hi

I have a datagridview filled with excel data, unbound to the table I want the data in. (see previous entry for that code).  Now I have a table with all the fields match integer, float, string.  I would like to put the data into the table called Stats using Linq, but sqlclient okay.  I have been fussing with it.  What ever happened to just dropping excel data into the database table like I did in 2012.  Well help or ideas would be great.

Thanks
