Question

我通过调用以下函数将Datatable加载到datagrid视图：

 Public Sub GetData(ByVal selectCommand As String, ByVal bindingSource As BindingSource, ByVal table As DataTable)
    Try
        Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\adm\Desktop\222.mdb"
        Me.dataAdapter = New OleDbDataAdapter(selectCommand, connectionString)
        Dim commandBuilder As New OleDbCommandBuilder(Me.dataAdapter)
        table.Locale = System.Globalization.CultureInfo.InvariantCulture
        Me.dataAdapter.Fill(table)
        bindingSource.DataSource = table
    Catch ex As OleDbException
        MessageBox.Show(ex.Message)
    End Try
End Sub

这是函数调用：

GetData("select * from products where ID=1 or ID=2", bindingSource1, t1)

现在，数据表是否定义了来自源数据库的列类型？因为当我尝试将数据添加到DateTime列时，它表示该列的类型为整数，但在Access中我可以看到它是一个DateTime列。那么我需要为每列指定每种类型，还是自动完成？

检查传递日期值的列的类型。确保该值不是int。如果是，请将其更改为datetime < / p>

修改转到数据表的属性，将列类型更改为datetime

VB.NET数据表列类型
