如何从 VB.NET 中的 DataSet 填充数组 [英] How to populate an array from a DataSet in VB.NET

问题描述

我正在尝试使用 VB.NET 2010 从仅包含特定列的数据集中填充数组.是否有任何代码可以直接填充数组或者我必须使用查询?

I'm trying to populate an array from a dataset with only a specific column using VB.NET 2010. Is there any code to populate the array directly or must I make use of a query?

推荐答案

更新:

假设你想要一个字符串数组:

Assuming you want an array of String:

Dim arr As String() = (From myRow In ds.Tables(0).AsEnumerable
                       Select myRow.Field(Of String)("yourColumnName")).ToArray

或列表:

Dim list As List(Of String) = (From myRow In ds.Tables(0).AsEnumerable
                               Select myRow.Field(Of String)("yourColumnName")).ToList

旧:

确保将 DisplayMember 设置为您要查看的列的名称:

Make sure the DisplayMember is set to the name of the column you want to see:

comboBox1.DataSource = ds.Tables(0)
comboBox1.DisplayMember= "NameOfColumn"

您可能还想将 ValueMember 属性设置为数据集中的 ID 字段名称.

You might also want to set the ValueMember property to the ID field name from your dataset.
