如何将 DataTable.Select() 的结果绑定到 ListBox 控件? [英] How do I bind the result of DataTable.Select() to a ListBox control?

问题描述

我有以下代码:

ListBox.DataSource = DataSet.Tables("table_name").Select("some_criteria = match")
ListBox.DisplayMember = "name"

DataTable.Select() 方法 返回 System.Data.DataRow 对象.

The DataTable.Select() method returns an array of System.Data.DataRow objects.

无论我在 ListBox.DisplayMember 属性中指定什么，我所看到的只是具有正确数量的项目的 ListBox 全部显示为 System.Data.DataRow我想要的值在 "name" 列中！

No matter what I specify in the ListBox.DisplayMember property, all I see is the ListBox with the correct number of items all showing as System.Data.DataRow instead of the value I want which is in the "name" column!

是否可以从 DataTable.Select() 绑定到结果数组，而不是循环遍历它并将每个数组添加到 ListBox?

Is it possible to bind to the resulting array from DataTable.Select(), instead of looping through it and adding each one to the ListBox?

(我对循环没有问题，但似乎不是一个优雅的结局！)

(I've no problem with looping, but doesn't seem an elegant ending!)

推荐答案

使用 DataView 代替.

ListBox.DataSource = new DataView(DataSet.Tables("table_name"), "some_criteria = match", "name", DataViewRowState.CurrentRows);
ListBox.DisplayMember = "name"
