我想将以下方法从 winform 转换为 WPF

private void btnOK_Click(object sender, System.EventArgs e)
{
    if (!EnterNewSettings())
        DialogResult = DialogResult.None;
}

我已经这样做了，但不起作用。

private void btnOK_Click(object sender, System.EventArgs e)
 { 
if (!EnterNewSettings())
 MessageBoxResult result = MessageBoxResult.None;
    }

您必须自己实现逻辑来确认和关闭您的消息框。

创建公共属性成功

Public bool Success {get;set;}

如果可以关闭表单并使其成功，请在您的确定按钮中使用此实现：

private void btnOK_Click(object sender, System.EventArgs e)
{ 
   if (!EnterNewSettings()){
   MessageBoxResult result = MessageBoxResult.None;
   }else{
      Success = true;
      Close();
   }
}

然后你可以检查属性成功

可能是我错过了一些语法，但我希望你能得到它要去的地方:)

不确定我是否理解问题，但在 WPFWindow.DialogResult中bool?，这意味着它可以是或true，具体取决于结果。如果要成功关闭 WPF，则需要设置为. 当您拥有它时，它将触发点击事件，但在设置之前不会为您关闭对话框。falsenullWindowDialogResulttrueButton.IsDefault = "true"ENTERDialogResult

private void btnOK_Click(object sender, System.EventArgs e)
{ 
   if (EnterNewSettings()) DialogResult = true;
}

你DialogResult的通过是因为Window.ShowDialog()

if (myDlg.ShowDialog() == true) ....

当你有Button.IsCancel = "true"然后，ESC它会触发点击事件并自动关闭对话框DialogResult=False

        w.Content = grid;

        w.ShowDialog();

        return (MessageBoxResult)w.Tag;
    }
