利用tableAdapter更新数据

UserData.UsersDataTable userDataTable = new UserData.UsersDataTable();
UserData.UsersRow usersRow = userDataTable.NewUsersRow();
usersRow.Name = p_Name;
usersRow.Gender = p_Gender;
usersRow.Email = p_Email;
usersRow.Mobile = p_Mobile;
usersRow.Telephone = p_Telephone;
usersRow.Address = p_Address;
usersRow.Country = p_Country;
usersRow.Province = p_Province;
usersRow.City = p_City;
usersRow.IDCard = p_IDCard;
usersRow.Passport = p_Passport;
usersRow.Fax = p_Fax;
usersRow.Creator = p_Creator;
usersRow.CreateDate = DateTime.Now;
usersRow.Modifier = p_Creator;
usersRow.UpdateDate = DateTime.Now;
userDataTable.AddUsersRow(usersRow);
if (new taUsers().Update(userDataTable) > 0)
{
return userDataTable[0].ID;
}
else return -1;
