Part II: Fill Dataset

很简单,基本上ADO.NET 的基本操作,没什么可值得说的。

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Data.Common;
  
using Artech.ApplicationBlock.DataMapping;
  
namespace Artech.ApplicationBlock.DataAccess
{
  /**//// <summary>
  /// Database defines a series of database-based operations.
  /// </summary>
  public abstract partial class Database : IDisposable,
  {
   
    public void FillDataSet(DataSet dataInfo, string commandText, IDictionary<string, object> parameters)
    {
      if (dataInfo.Tables.Count == 0)
      {
        DataTable table = dataInfo.Tables.Add("Table1");
      }
  
      this.FillDataSet(dataInfo, dataInfo.Tables[0].TableName, this._defaultCommandType, commandText, parameters);
    }
  
    public void FillDataSet(DataSet dataInfo, string tableName, string commandText, IDictionary<string, object> parameters)
    {
      this.FillDataSet(dataInfo, tableName, this._defaultCommandType, commandText, parameters);
    }
  
    public void FillDataSet(DataSet dataInfo, string tableName, CommandType commandType, string commandText, IDictionary<string, object> parameters)
    {
      DbCommand selectComand = this.Connection.CreateCommand();
      selectComand.CommandText = commandText;
      selectComand.CommandType = commandType;
      this.DatabaseAdapter.SelectCommand = selectComand;
      this.DatabaseAdapter.Fill(dataInfo, tableName);
    }
  }
}
