Confirmation Box in C# wpf
提问by user2622971
I want to show confirmation Box in C# code. I've seen above solution for that but it shows me exception at 'Yes' as 'System.Nullable' does not contain definition for 'Yes'. How should I remove this error?
我想在 C# 代码中显示确认框。我已经看到了上面的解决方案，但它向我显示了“是”的异常，因为“System.Nullable”不包含“是”的定义。我应该如何消除这个错误？
private void listBox1_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
{
if (sender is ListBoxItem)
{
ListBoxItem item = (ListBoxItem)sender;
Harvest_TimeSheetEntry entryToDelete = (Harvest_TimeSheetEntry)item.DataContext;
DialogResult dialogResult = System.Windows.Forms.MessageBox.Show("Are you sure?", "Delete Confirmation", MessageBoxButtons.YesNo);
if (dialogResult == DialogResult.Yes) // error is here
{
Globals._globalController.harvestManager.deleteHarvestEntry(entryToDelete);
}
else
{
System.Windows.MessageBox.Show("Delete operation Terminated");
}
}
}

Instead of using WinForm MessageBox, use the MessageBoxprovided by WPF and later use MessageBoxResultinstead of DialogResultin WPF.
不使用 WinForm MessageBox，而是使用WPF 提供的MessageBox，稍后使用MessageBoxResult而不是DialogResult在 WPF 中使用。

喜欢：
MessageBoxResult messageBoxResult = System.Windows.MessageBox.Show("Are you sure?", "Delete Confirmation", System.Windows.MessageBoxButton.YesNo);
if (messageBoxResult == MessageBoxResult.Yes)
//...........
