is linq sql insertonsubmit() theme sql injection attack?

i have formula this:

var newmsg = new msg
{
    var1 = var1,
    var2 = var2
};

using (appdatacontext appdatacontext = new appdatacontext(connectionstring))
{
    appdatacontext.cclass.insertonsubmit(newmsg);
    appdatacontext.submitchanges();
}

after reading i trust same explanation applies.
