Question

我正在使用ASP.Net MVC，Angular.js，SQL Server和Fusion图表构建仪表板。我的所有图表数据都存储在数据库中，我通过存储过程获取它们。现在我需要将存储过程的结果传递给Json / XML，只有Fusion Charts支持的格式。转换此数据的最佳方法是什么：

Hour Input   Output  InTarget  OutTarget
7    22314   18537    6500      4875
8    36395   29931    6500      4875
9    32661   28518    6500      4875
10   34895   29793    6500      4875
11   30300   26538    6500      4875
12   31011   26898    6500      4875
13   16363   13716    6500      4875

进入这个Json？

                            },

                            }
                        ]
                    }
                ]
            }

我想要做的是：

存储过程到数据表
将每列放入单独的数组
以下面的格式将数组转换为Json

这是最好的（性能）方法吗？

编辑：

        public Series[] GetGraphData(string sp)
    {
        var connection = ConfigurationManager.ConnectionStrings["EFDbContext"].ConnectionString;
        using (var da = new SqlDataAdapter("exec " + sp, connection))
        {
            var dt = new DataTable();

            da.Fill(dt);
            da.FillSchema(dt, SchemaType.Mapped);


            Series[] arrSeries = new Series[dt.Columns.Count];


            foreach(DataColumn dc in dt.Columns)
            {
                if (dc.Ordinal == 0)
                {
                  //Category here
                }
                else
                {
                    var strarr = dt.Rows.Cast<DataRow>().Select(row => row[dc.Ordinal]).ToList();

                    Series s = new Series()
                    {
                        seriesname = dc.ColumnName,
                        renderas = "Line",
                        data = strarr.Select(o => new SeriesValue { value = o.ToString() }).ToList()
                    };

                    arrSeries[dc.Ordinal] = s;
                }
            }

            return arrSeries;
        }
    }

Answer 1

我会按照你的说法将所有数据加载到数据表中，然后有一个Series对象：

class Series{
  public string seriesname{get;set;}
  public string renderas{get;set;}
  public IList<SeriesValue> data{get;set;}
}

class SeriesValue{
  public string value{get;set;}
}

并将一个Series数组返回到前端，序列化为JSON。然后，您已经构建了dataset数组，并且您不需要对其进行任何其他处理。

我预计性能瓶颈在于从数据库加载数据并将其发送到客户端。实际转换为json在宏观方案中并不重要。

什么是最快的方法？
