字符串中的 DependencyProperty

问题描述

如何将属性名称(字符串形式)转换为 DependencyProperty?

我有一组属性名称、字符串形式的值和一个 DependencyObject.现在我想将这些属性值设置为 DependencyObject.关于如何实现这一点的任何想法?

谢谢.

解决方案

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

var 描述符 = DependencyPropertyDescriptor.FromName(财产名称，依赖对象.GetType(),依赖对象.GetType());//现在你可以设置属性值descriptor.SetValue(dependencyObject, value);//也可以使用依赖属性本身var property = descriptor.DependencyProperty;dependencyObject.SetValue(property, value);

How do I convert a property name (in string) to a DependencyProperty?

I have a set of property names, its values in string and a DependencyObject. Now I want to set these property values to the DependencyObject. Any idea on how this can be achieved?

Thanks.

解决方案

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);
