将相同的特性设置为多个相同的对象(不要重复)

本文关键字：对象 设置 | 更新日期: 2023-09-27 18:19:54

有什么解决方案可以简化这段代码吗？我只想在几个相同类型的对象中设置相同的属性。这些对象是Windows 8应用程序中的文本框。我想可能是Array和foreach。。。但我不确定感谢

private void makeVisible(int x)
        {
            if (x == 1)
            {
                field2.Visibility = Visibility.Visible;
                field3.Visibility = Visibility.Visible;
                field4.Visibility = Visibility.Visible;
                field6.Visibility = Visibility.Visible;
                field8.Visibility = Visibility.Visible;
                field9.Visibility = Visibility.Visible;
                field11.Visibility = Visibility.Visible;
            }
            if (x == 0)
            {
                field2.Visibility = Visibility.Collapsed;
                field3.Visibility = Visibility.Collapsed;
                field4.Visibility = Visibility.Collapsed;
                field6.Visibility = Visibility.Collapsed;
                field8.Visibility = Visibility.Collapsed;
                field9.Visibility = Visibility.Collapsed;
                field11.Visibility = Visibility.Collapsed;
                errorReporter.Visibility = Visibility.Collapsed;
            }
        }

将相同的特性设置为多个相同的对象(不要重复)

您至少可以做以下事情：

var visibility = x == 0 ? Visibility.Collapsed : Visibility.Visible;
field2.Visibility = visible;
field3.Visibility = visible;
// etc

如果你想使用数组，你甚至可以做以下事情，但我不确定这是否是一个改进：

foreach (var obj in new[] { field1, field2, field3 ... })
{
    obj.Visibility = x == 0 ? Visibility.Collapsed : Visibility.Visible;
}

private void makeVisible(int x)
{
    var boxes = new TextBox[] { field2, field3... };
    foreach (TextBox box in boxes)
    {
        box.Visibility = (x == 1) ? Visibility.Visible : Visibility.Collapsed;
    }
    if (x == 0)
    {
        errorReporter.Visibility = Visibility.Collapsed;
    }
}

List<MyFieldType> fields=new List<MyFieldType> {field2, field3, field4, field6, field8, field9, field11};
foreach(MyFieldType field in fields)
   {
   if(x==1)
      {
      field.Visibility=Visibility.Visible;
      }
   else if(x==0)
      {
      field.Visibility=Visibility.Collapsed;
      }
   }

使用集合存储对象并对其进行迭代。

您肯定需要遍历上面回答的元素，但您不必手动构建列表，使用Reflection来简化它：

this.GetType().GetProperties().Where(pi=>pi.PropertyType == typeof(TextBox))
