Question

您好我想缩短此代码：

<div id="txt" contenteditable="true">
  <span id="annyoing-html" contenteditable="false">
    <span class="badge">I AM ANNOYING</span>
  </span>&nbsp;
  <span id="annyoing-html" contenteditable="false">
    <span class="badge">I AM ANNOYING TOO</span>
  </span>
</div>

稍后我会添加更多设置加载，我需要缩短它但我不知道如何。

我试着把这段代码变成这样的字符串：

tb1n.Text = Settings2.Default.tb1n;
tb2n.Text = Settings2.Default.tb2n;
tb3n.Text = Settings2.Default.tb3n;
tb4n.Text = Settings2.Default.tb4n;
tb5n.Text = Settings2.Default.tb5n;
tb6n.Text = Settings2.Default.tb6n;
tb7n.Text = Settings2.Default.tb7n;
tb8n.Text = Settings2.Default.tb8n;
tb9n.Text = Settings2.Default.tb9n;
tb10n.Text = Settings2.Default.tb10n;
tb11n.Text = Settings2.Default.tb11n;
tb12n.Text = Settings2.Default.tb12n;
tb13n.Text = Settings2.Default.tb13n;

但后来我意识到这不是一个好的解决方案，因为从字符串执行代码很难做到而且我不喜欢它。

您可以创建可视树辅助类并在视图上查找所有文本框实例。

助手类：

public static class TreeHelper
    {
        public static IEnumerable<T> FindVisualChildren<T>(this DependencyObject depObj) where T : DependencyObject
        {
            if (depObj == null) yield break;

            for (var i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
            {
                var child = VisualTreeHelper.GetChild(depObj, i);
                var children = child as T;
                if (children != null)
                    yield return children;

                foreach (T childOfChild in FindVisualChildren<T>(child))
                    yield return childOfChild;
            }
        }
    }

拨打

var children = this.FindVisualChildren<TextBox>(); foreach (var child in children) { child.Text = Settings.Default[child.Name].ToString(); }

您可以将TextBox和字符串存储在如下列表中：

        List<TextBox> TextBoxes = new List<TextBox>() {
            tb1n,
            tb2n,
            tb3n,
            ...
        };

        List<string> mySettings = new List<string>(){
            Settings2.Default.tb1n,
            Settings2.Default.tb2n,
            Settings2.Default.tb3n,
            ...
        };

        foreach  (TextBox item in TextBoxes)
        {
            item.Text = mySettings[TextBoxes.FindIndex(a => a.Name == item.Name)];
        }

然后你可以使用foreach循环给每个TextBox它的Text属性值。

如何在C＃中使这种类型的代码更短？
