推荐答案

您可以使用< code> System.Windows.Controls.Primitives</code>中的GetVisualDescendants.命名空间.
< pre>
IEnumerable< type> o =(((DependencyObject)_myGrid).GetVisualDescendants().OfType< type>();

foreach(在o中输入objChild类型)
{
如果(objChild.Name =="name")
{
//做点事
}
} pre>


这里的Type是您要查找的控件的类型.

You could use the GetVisualDescendants from the <code>System.Windows.Controls.Primitives</code> namespace.
<pre>
IEnumerable<type> o = ((DependencyObject)_myGrid).GetVisualDescendants().OfType<type>();

foreach(Type objChild in o)
{
if (objChild.Name == "name")
{
//Do something
}
}pre>


Here Type is the type of control you are looking for.

我尝试发生此错误:

Error 1 ''System.Windows.DependencyObject'' does not contain a definition for ''GetVisualDescendants'' and no extension method ''GetVisualDescendants'' accepting a first argument of type ''System.Windows.DependencyObject'' could be found (are you missing a using directive or an assembly reference?)

i try it this error Occurred:
