c# - 单击它更改内容并返回原始状态的按钮

Question

我有一个名为“验证”的按钮。单击时应将其内容更改为“正在验证...”，处理完成后应显示“已验证”。我们应该如何做到这一点？我是 wpf 的新手。任何帮助将不胜感激。

private void btnVerify_Click(object sender, RoutedEventArgs e)  
{  
    btnVerify.Content = new BitmapImage(new Uri("Verifying.png", UriKind.Relative));
    VerifyData(); // this takes almost few seconds to few minutes 
    btnVerify.Content = new BitmapImage(new Uri("Verified.png", UriKind.Relative)); 
}

因为您是 WPF 的新手，所以我假设您没有使用 MVVM。在这种情况下:

Hook 到 Click事件和方法中:

OnVerifyClick(object sender, RoutedEventArgs e)
{
    Button verifyButton = sender as Button;
    if(verifyButton == null) { return; }

    verifyButton.Content = "Verifying...";
    DoProcessing();
    verifyButton.Content = "Verified";    
}
