Solution

you should keep its type to whatever is the type of id column in database.

Though in your case here if you want to use count1 only in this query you can keep it string/int. I also see a problem in your query. it should be 

"DELETE FROM Table1 Where(Table1.count)=" + count1; //note i have removed single quotes

unless your id column is string in database.
