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
