string deptid = tboxdeptid.Text.Trim();
            string deptname = tboxdeptname.Text.Trim();
            string deptphone = tboxdeptphone.Text.Trim();

            string sqlstr = "insert into dept (deotid,deptname,deptphone)" +
                " values('"+deptid+"','"+deptname+"','"+deptphone+"')";
            string connstr = "server=(local);intergrated security=true;database=StuM2000";

            SqlConnection sqlconn = new SqlConnection(connstr);//不支持关键字: “intergrated security”。
            sqlconn.Open();
那个提示是什么意思啊？怎么解决它啊？请高手帮帮我吧~~~~~

string connstr = @"Data Source=.;Initial Catalog=数据库名;Integrated Security=True";
SqlConnection sqlconn = new SqlConnection(connstr);
