调用SQL存储过程，插入功能，获取返回值

[c#]代码库

public static bool Insert_EvaluationInfo(int pvoteid, string pecontent, int plimited, out int id)
        {
            bool successful = false;
            id = 0;
            try
            {
                using (SqlConnection conn = new SqlConnection(strConn))
                {
                    SqlCommand cmd = new SqlCommand("Insert_EvaluationInfo", conn);
                    cmd.CommandType = CommandType.StoredProcedure;

                    SqlParameter spvoteid = new SqlParameter("@pVoteID", SqlDbType.Int);
                    spvoteid.Value = pvoteid;
                    SqlParameter spcontent = new SqlParameter("@pEContent", SqlDbType.NVarChar, 200);
                    spcontent.Value = pecontent.Trim();
                    SqlParameter splimited = new SqlParameter("@pLimitedNum", SqlDbType.Int);
                    splimited.Value = plimited;
                    SqlParameter resultid = new SqlParameter("@resultid", SqlDbType.Int);
                    resultid.Direction = ParameterDirection.ReturnValue;

                    cmd.Parameters.AddRange(new SqlParameter[] { spvoteid, spcontent, splimited, resultid });

                    conn.Open();
                    if (cmd.ExecuteNonQuery().Equals(1))
                    {
                        int.TryParse(cmd.Parameters["@resultid"].Value.ToString(), out id);
                        successful = true;
                    }
                    conn.Close();
                }
            }
            catch (Exception)
            {
                successful = false;
                //throw;
            }
            return successful;
        }
尽量不要使用out
