to fix that, try with ToString method

C#

var sql="insert into grade (course_name) values(@0)";
db.Execute(sql,add.ToString());

var sql="insert into grade (course_name) values(@0)";
db.Execute(sql,program);
db.Execute(sql,program1);

thanks so much,you really a good programme,but is there a way i can iterate over texboxes dan rather calling the execute everytime,because am having 8 textboxes of program,grade which means i call the db.execute 8 times
