使用DataSource属性填充DataTable [英] Fill DataTable using DataSource property

问题描述

大家好，

我想用显示在DataGridView/ListBox中的当前数据填充DataTable.
在C#中，我曾经写过:

Hello All,

I want to fill my DataTable with the current data displayed in DataGridView/ListBox.
In c# i used to write:

DataTable dt = (DataTable) grdData.DataSource

但是在这里我正在使用VB.Net，对它来说我是一个新手.
我尝试在Google上进行搜索，但到处都在寻找如何将DataTable分配给datagridview.
我什至尝试过:

But here i am using VB.Net and i am very new to it.
I tried to search on google but everywhere i am finding how to assign DataTable to a datagridview.
I even tried this:

Dim dt as DataTable
dt = grdData.DataSource As DataTable

但它不起作用.

谁能告诉我如何在VB.Net中做到这一点.

谢谢，
Nagendra.

but its not working.

Can anybody tell me how to do this in VB.Net.

Thanks,
Nagendra.

推荐答案

尝试此

作为DataTable的Dim dt = DirectCast(grdData.DataSource，DataTable)

我不确定，但是您可以尝试.

try this

Dim dt As DataTable = DirectCast(grdData.DataSource, DataTable)

iam not sure but you can try.
