Get the propertyInfo by the path to it?

Question

I want to get the propertyInfo by the path that look like this:

string path = "window.position.x";

Here an example:

PropertyInfo p = typeof(WindowManager).GetProperty(path);

the WindowManager has a property called "window", which has a property called "position" which again has the property "x".

Is there some way to achieve this? Unfortunatelly GetProperty doesn't work with such a path.

Answer 1

You can split your path and iterate through metadata. Try this code:

var type = typeof(WindowManager);
PropertyInfo property;
foreach (var prop in path.Split('.'))
{
    property = type.GetProperty(prop);
    if (property == null)
    {
        // log error
        break;
    }
    type = property.PropertyType;
}

// now property is x

Note that you should check property on each iteration to make sure your path is valid
