As per my understanding
SqlParameter Registration_ID = new SqlParameter("@Registration_ID", txtReg_ID);
should be
SqlParameter Registration_ID = new SqlParameter("@Registration_ID", txtReg_ID.Text);
SqlParameter sex = new SqlParameter ("@Sex", rdbMale.);
should be
SqlParameter sex = new SqlParameter ("@Sex", rdbMale.Text);
and so on

It seems there are some errors @ line 66, 71 & 78
SqlParameter Registration_ID = new SqlParameter("@Registration_ID", txtReg_ID);
&
SqlParameter sex = new SqlParameter ("@Sex", rdbMale.);
&
SqlParameter Picture = new SqlParameter("@Picture", PicturePre);
