推荐答案

您可以获得 DependencyPropertyDescriptor 使用DependencyPropertyDescriptor.FromName方法，然后从该描述符中获取依赖项属性标识符。

You can get DependencyPropertyDescriptor using DependencyPropertyDescriptor.FromName method and then get dependency property identifier from this descriptor.

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);
