dapper的一个小扩展以支持dataset

废话不多，直接上方法

         public static DataSet ExecuteDataSet(this IDbConnection cnn, IDbDataAdapter adapter, string sql, object param = null, bool buffered = true, int? commandTimeout = null, CommandType? commandType = null)
         {
             var ds = new DataSet();
             var command = new CommandDefinition(sql, (object)param, null, commandTimeout, commandType, buffered ? CommandFlags.Buffered : CommandFlags.None);
             var identity = new Identity(command.CommandText, command.CommandType, cnn, null, param == null ? null : param.GetType(), null);
             var info = GetCacheInfo(identity, param, command.AddToCache);
             bool wasClosed = cnn.State == ConnectionState.Closed;
             if (wasClosed) cnn.Open();
             adapter.SelectCommand = command.SetupCommand(cnn, info.ParamReader);
             adapter.Fill(ds);
             if (wasClosed) cnn.Close();
             return ds;
         }

在Query方法下面添加即可

使用Demo

var mysqlDs = con.ExecuteDataSet(new MySqlDataAdapter(), "SELECT * FROM wjf_role_relation where ROLE_ID=@ROLE_ID", new { ROLE_ID = '1' });
