How to get nested properties

Question

I want to retrieve a PropertyInfo, Here the code :

string propertyName="Text";
PropertyInfo pi = control.GetType().GetProperty(propertyName);

it works fine but if I want to retrieve nested properties, it returns null :

string propertyName="DisplayLayout.Override.RowSelectors";
PropertyInfo pi = control.GetType().GetProperty(propertyName);

Is there any way to get nested properties ?

Best Regards,

Florian

Edit : I have a new problem now, I want to get a property which is an array :

string propertyName="DisplayLayout.Bands[0].Columns";
PropertyInfo pi = control.GetType().GetProperty(propertyName)

Thank you

Yes:

public PropertyInfo GetProp(Type baseType, string propertyName)
{
    string[] parts = propertyName.Split('.');

    return (parts.Length > 1) 
        ? GetProp(baseType.GetProperty(parts[0]).PropertyType, parts.Skip(1).Aggregate((a,i) => a + "." + i)) 
        : baseType.GetProperty(propertyName);
}

Called:

PropertyInfo pi = GetProp(control.GetType(), "DisplayLayout.Override.RowSelectors");

Recursion for the win!

Just do the same again on the PropertyType you just got for the property (and repeat as often as you need):

PropertyInfo property = GetType().GetProperty(propertyName);
PropertyInfo nestedProperty = property.PropertyType.GetProperty(nestedPropertyName)
