如何将多个数据视图合并为一个？ [英] How to merge multiple dataviews into one?

问题描述

我有三个数据视图（dataview1，dataview2和dataview3）。它们的类型为System.Data.DataView，并且所有三个具有相同的列。是否有一种简单的方法可以将它们合并为一个，所以我有一个dataview，其中包含dataview1中的行，然后是dataview2，然后是dataview3？

I have three dataviews (dataview1, dataview2, and dataview3). These are of type System.Data.DataView, and all three have the same columns. Is there an easy way to merge them into one, so I have one dataview with rows from dataview1, followed by dataview2, and then dataview3?

推荐答案

Dim dataview1 As DataView = new DataView()
Dim dataview2 As DataView = new DataView()

'' given the tables are not null you can then merge like this

dataview1.Table.Merge(dataview2.Table)
