Shorter way to evaluate DialogResult after calling Window.ShowDialog

I have seen many code snippets like:

Copy Code

frm.ShowDialog();
if (frm.DialogResult.HasValue && frm.DialogResult.Value) 
{
   // do something here
}

Copy Code

DialogResult result = frm.ShowDialog();
if (result.HasValue && result.Value)
{
   // do something here
}

This double check is done because DialogResult is of nullable type: bool?, but evaluation can be as simple as:

Copy Code

frm.ShowDialog();
if (frm.DialogResult.Equals(true))
{
   // do something here
}
