问题描述

大家好

我有一个BindingSource绑定到一个DataTable(来自sql数据库),有几列

I have a BindingSource bound to a DataTable(from sql database) with several columns

我需要得到来自绑定源的所有列名称并将它们添加到名称的arraylist中

I need to get all columns names from binding source and add them to an arraylist of names

如何做到这一点?

感谢您的帮助

推荐答案

Dim columnNames() As String = CType(bsCustomers.DataSource, DataTable).
        Columns.Cast(Of DataColumn).
        Select(Function(c) c.ColumnName).ToArray()

For Each col As String In columnNames
    Console.WriteLine(col)
Next

编辑,对于类型化的数据集,可能有多个表格,这里我定位第一个表格。

Edit, for a typed data set were there may be more than one table, here I target the first table.

Dim cols = CType(bsCustomers.DataSource, DataSet).
    Tables(0).
    Columns.Cast(Of DataColumn).
    Select(Function(c) c.ColumnName).ToArray

For Each col In cols
    Console.WriteLine(col)
Next
