Dear friends:

I need a method for getting properties values of an Xpo Object. Supose i have an objet thas is a person and has a name property and a relation
of address where he has lived. I need somethin like this

GetPropertyValue("Name") and returns the value of the proptery name

GetPropertyValue("Address[0].City") and returns Ney York

GetPropertyValue("Wife.Name") Wife is another Xpo Object

Note that i need to lookup for the name property as a string because this will be a variable in a line of text. For example

Dear <<Name>> we know you have changed your city to <<Adress[0].City>> with your wife <<Wife.Name>>

Wich is the best approach?

Best Regards

Hi Manel.
You can access values of object properties using the XPBaseObject.GetMemberValue method. However, it does not support nested property paths and indexed access. You should implement parsing of such complex paths yourself.

C#
public static object GetNestedMemberValue(this XPBaseObject o, string PropertyName)  
{  
    if (PropertyName.Contains("."))  
    {  
        int i = PropertyName.IndexOf('.');  
        string baseProp = PropertyName.Substring(0, i);  
        object oBO = o.GetMemberValue(baseProp);  
        if (oBO == null || !(oBO is XPBaseObject)) return null;  
        string subProp = PropertyName.Substring(i + 1, PropertyName.Length - i - 1);  
        return (o.GetMemberValue(baseProp) as XPBaseObject).GetNestedMemberValue(subProp);  
    }  
    else return o.GetMemberValue(PropertyName);  
}
