将VB转换为C＃

Question

I need a little help converting some VB.NET code to C#. I have tried several "code converters" but none of them are giving me back a workable response.

Here's the code:

If Me.OrdersDataGridView.SelectedRows.Count > 0 Then
Dim editForm As New Order(Me.NorthwindDataSet, _
    Me.NorthwindDataSet.Orders.Rows.IndexOf_
    (CType(CType(Me.OrdersDataGridView.SelectedRows(0)._
    DataBoundItem, DataRowView).Row, NorthwindDataSet.OrdersRow)))
    editForm.Show()
End If

Any help with this is greatly appreciated!

EDIT: here's a link to the original article I found this in.

Answer 1

Try this:

if (this.OrdersDataGridView.SelectedRows.Count > 0)
{
    NorthwindDataSet.OrdersRow row = (NorthwindDataSet.OrdersRow)
                                       ((DataRowView)this.OrdersDataGridView
                                            .SelectedRows(0).DataBoundIte).Row;

    Order editForm = new Order(
                           this.NorthwindDataSet,
                           this.NorthwindDataSet.Orders.Rows.IndexOf(row));

    editForm.Show();
}

Answer 2

if (this.OrdersDataGridView.SelectedRows.Count > 0)
{
    Order editForm = new Order(this.NorthwindDataSet,
        this.NorthwindDataSet.Orders.Rows.IndexOf((NorthwindDataSet.OrdersRow)((DataRowView)this.OrdersDataGridView.SelectedRows[0].DataBoundItem).Row);
    editForm.Show();
}

Ok I think I typed that correct.

Answer 3

If code converters are failing here, it's likely because you need a reference in your Visual Studio solution to that specific database in order for it to work.

The conversion should be something like:

if (this.OrdersDataGridView.SelectedRows.Count > 0)
{
    var dataRowView = (DataRowView) this.OrdersDataGridView.SelectedRows(0).DataBoundItem;
    var ordersRow = (NorthwindDataSet.OrdersRow) dataRowView;
    var editForm = new Order(this.NorthwindDataSet, ordersRow)
    editForm.Show()
}
