这是我在数据库中插入用户的代码。请让我知道在哪里应用 try catch 块以防止在这种情况下发生任何类型的异常。
if (ModelState.IsValid)
{
user.Type = 'J';
user.DateOfJoining = DateTime.Now;
using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["DefaultConnectionString"].ToString()))
{
using (SqlCommand command = new SqlCommand("SignupUser", connection))
{
command.CommandType = System.Data.CommandType.StoredProcedure;
command.Parameters.AddWithValue("@FirstName",user.FirstName);
command.Parameters.AddWithValue("@LastName",user.LastName);
command.Parameters.AddWithValue("@Email",user.Email);
command.Parameters.AddWithValue("@Password",user.Password);
command.Parameters.AddWithValue("@Mobile",user.Mobile);
command.Parameters.AddWithValue("@City",user.City);
command.Parameters.AddWithValue("@StateProvince",user.StateProvince);
command.Parameters.AddWithValue("@Country",user.Country);
command.Parameters.AddWithValue("@Type",user.Type);
command.Parameters.AddWithValue("@DateOfJoining",user.DateOfJoining);
connection.Open();
int result = command.ExecuteNonQuery();
connection.Close();
return RedirectToAction("account");
}
}
}
