Is there a builtin confirmation dialog in Windows Forms?

I'd like to create a simple confirm dialog saying "Please check the information and if you're sure it's correct, click OK."

Is there something built in like t开发者_C百科his?

Here is an example. You can try something like this.

var confirmResult =  MessageBox.Show("Are you sure to delete this item ??",
                                     "Confirm Delete!!",
                                     MessageBoxButtons.YesNo);
if (confirmResult == DialogResult.Yes)
{
    // If 'Yes', do something here.
}
else
{
    // If 'No', do something here.
}

You can also try MessageBoxButtons.OKCancel instead of MessageBoxButtons.YesNo. It depends on your requirements.

2. If you have .Net Framework 4.6 or above please try this.

MessageBoxResult confirmResult = MessageBox.Show("Are you sure to delete this item ??", "Confirm Delete!!", MessageBoxButton.YesNo);`

if (confirmResult == MessageBoxResult.Yes)
{
   // If 'Yes', do something here.
}
else
{
   // If 'No', do something here.
}

MessageBox.Show? You can specify the title, caption, and a few options for which buttons to display.

On the other hand, if you're asking people to confirm information, that sounds like you probably want to show a custom dialog - which you can do with Form.ShowDialog.

In .Net Core you can do it like this:

DialogResult dialogResult= MessageBox.Show("Are you sure to delete?", "Confirm", MessageBoxButtons.YesNo);

if (dialogResult == DialogResult.Yes)
{
    //if code here....            
}
else
{
   //else code here.... 
}

Output Result
