来自字符串的DependencyProperty

Question

如何将属性名称(在字符串中)转换为DependencyProperty？

我有一组属性名称,其值以字符串和a表示DependencyObject.现在我想将这些属性值设置为DependencyObject.有关如何实现这一点的任何想法？

谢谢.

您可以使用DependencyPropertyDescriptor.FromName方法获取DependencyPropertyDescriptor,然后从此描述符获取依赖项属性标识符.

var descriptor = DependencyPropertyDescriptor.FromName(
    propertyName,
    dependencyObject.GetType(),
    dependencyObject.GetType());

// now you can set property value with
descriptor.SetValue(dependencyObject, value);

// also, you can use the dependency property itself
var property = descriptor.DependencyProperty;
dependencyObject.SetValue(property, value);
