    Example
    This sample demonstrates usage of Item property. It retrieves data from a column of composite type in a table and renders the data to console. To run the samples successfully you have to create server objects with the following script: CREATE TYPE tperson AS (name text, age integer); CREATE TABLE personnel (id integer, person tperson);
    static void ReadData(PgSqlConnection conn)  
    { 
      string str = "SELECT * FROM personnel"; 
      PgSqlCommand pgCommand = new PgSqlCommand(str,conn); 
      PgSqlDataReader pgReader = pgCommand.ExecuteReader(); 
      while (pgReader.Read())  
      { 
        Console.Write(pgReader.GetInt32(0) + "\t"); 
        PgSqlRow pgRow = pgReader.GetPgSqlRow(1);
        if (pgRow == null) 
        {
          Console.WriteLine();
          continue;
        }
        Console.Write(pgRow[0] + "\t");
        Console.WriteLine(pgRow["age"]);
      } 
      pgReader.Close(); 
    }
    Sub ReadData(ByVal conn As PgSqlConnection)
      Dim str As String = "SELECT * FROM personnel"
      Dim pgCommand As PgSqlCommand = New PgSqlCommand(str, conn)
      Dim pgReader As PgSqlDataReader = pgCommand.ExecuteReader()
      While pgReader.Read()
        Console.Write(pgReader.GetInt32(0) & Chr(9))
        Dim pgRow As PgSqlRow = pgReader.GetPgSqlRow(1)
        If pgRow Is Nothing Then
          Console.WriteLine()
        Else
          Console.Write(pgRow(0) & Chr(9))
          Console.WriteLine(pgRow("age"))
        End If
      End While
      pgReader.Close()
    End Sub
