C# “WPF获取所有控制”；内容“；

如果WPF控件具有内容变量，将如何检查

我正在使用以下代码遍历所有控件：

public void Translate(Visual myVisual)
{
    for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++)
    {
        // Retrieve child visual at specified index value.
        Visual childVisual = (Visual)VisualTreeHelper.GetChild(myVisual, i);

        //How can I check wether childVisual has a Content-Variable or hasn't?
        //So check if this: childVisual.Content is existing

        // Enumerate children of the child visual object.
        Translate(childVisual);
    }
}

---

但是这是肮脏的，还有其他的可能性吗？

最简单的方法是检查您的

视觉

是否是

内容控件。通常，所有具有
Content
属性的WPF控件都派生自
ContentControl

for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++)
{
    // Retrieve child visual at specified index value.
    Visual childVisual = (Visual)VisualTreeHelper.GetChild(myVisual, i);

    //How can I check whether childVisual has a Content-Variable or hasn't?
    var childContentVisual = childVisual as ContentControl;
    if(childContentVisual != null)
    {
        var content = childContentVisual.Content;
        ...
    }

    // Enumerate children of the child visual object.
    Translate(childVisual);
}

for（int i=0；i

您也可以使用反射来查看内容属性是否存在，但这样做会更慢、更麻烦。
谢谢！不知道这个类存在。解决了的
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++)
{
    // Retrieve child visual at specified index value.
    Visual childVisual = (Visual)VisualTreeHelper.GetChild(myVisual, i);

    //How can I check whether childVisual has a Content-Variable or hasn't?
    var childContentVisual = childVisual as ContentControl;
    if(childContentVisual != null)
    {
        var content = childContentVisual.Content;
        ...
    }

    // Enumerate children of the child visual object.
    Translate(childVisual);
}
