Abstract

The invention discloses a data filling method and device. The data filling method comprises the following steps: a data filling request is acquired, wherein the data filling request carries data sources, a preset name and a preset type, the preset name is the name of the column of the data sources, and the preset type is the data type of the preset name; data column objects are created according to the preset name and the preset type; an incidence relation between index subscripts of the data column objects and the preset name is established; the data sources are used for filling data into an object array in rows according to the incidence relation. By the adoption of the data filling method and device, the problems that the error rate is high and filling efficiency is low when a data table in a memory is filled with data in the prior art are solved, and the effects that the execution efficiency is improved, the readability of codes is improved at the same time, and the data are easy to modify when the data of the data sources change are achieved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data filling method and device. Background technique [0002] Usually we use the DataTable class to create an in-memory data table for saving data objects, so as to facilitate the transfer of data between program functions, or write data to the database. [0003] In the prior art, there are two methods for filling data in DataTable: [0004] (1) Use the Add(DataRow) method, specifically, add the specified DataRow (row data) to the DataRowCollection (row collection), the code used can be as follows: [0005] [0006] (2) Use the Add(Object[]) method, specifically, create an Object (row object) using the specified value, and add it to the DataRowCollection (a collection of rows), the code used can be as follows: [0007] [0008] Use method (2) to fill each column of data and use subscripts to assign values, for example: dr[0], dr[1], we cannot know what 0 and 1 specificall...
