Question

我在我的xaml文件中有6个类似的值：

<TextBlock Name="Player0" Visibility="Hidden" Text="Player 0" />
<TextBlock Name="Player1" Visibility="Hidden" Text="Player 1" />
...

但是我想用这样的for循环改变Visibilty：

for (int i = 0; i<6; i++)
{
  String test = "Player" + i;
  test.Visibility = Visibility.Visible;
}

但它没有用。

有人可以帮助我吗？

Answer 1

试试这个：

for (int i = 0; i < 6; i++)
{
  TextBlock test = (TextBlock)this.FindName("Player" + i);
  test.Visibility = Visibility.Visible;
}

希望这有帮助！

xaml文件中的对象类型是TextBlock，但它在cs文件中是String。你确定吗？如果是，请在cs文件中更改类类型，如

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
