DependencyProperty from string

问题:

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.

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);
