I work on .net core 6 vs 2022 i see function have telement
but i don't know what this mean
can you show me please ?

What I have tried:

public List<TElement> SQLQuery<TElement>(string sql, string? connectionStringName = null, params StoredParameter[] parameters)
          string ConnectionString = connectionStringName == null ? _ApplicationConfiguration.ConnectionString : _ApplicationConfiguration.GetConnectionString(connectionStringName);
          using (SqlConnection sqlConn = new SqlConnection(ConnectionString))
              using (SqlCommand cmd = new SqlCommand(sql, sqlConn))
                  cmd.CommandText = sql;
                  cmd.CommandType = System.Data.CommandType.StoredProcedure;
                  cmd.CommandTimeout = (int)TimeSpan.FromMinutes(5).TotalSeconds;
                  foreach (var parameter in parameters)
                      var paramter = cmd.CreateParameter();
                      paramter.ParameterName = parameter.ParameterName;
                      paramter.Value = parameter.ParameterValue;
                      if (!string.IsNullOrEmpty(parameter.TypeName))
                          paramter.SqlDbType = SqlDbType.Structured;
                          paramter.TypeName = parameter.TypeName;

                  using (var reader = cmd.ExecuteReader())
                      var result = reader.MapToList<TElement>();
                      return result;

It's not telement, it's TElement: it's a type placeholder that makes the method work with multiple types without you having to code for all of them separately.
