Question

I have a Bank Object that has several nested objects/properties/methods as well as wrapping around a com object. There is limited documentation to this lib and I want to change the Banking Number in the Object but I have no idea what property’s name is, or how far down in the object tree. However I do know the value of the property is 1231241. How can I search a object for that value to find it and change it ?

I have tried:

• digging through the watch window, but the object is huge
• Bug Aid this is still in beta and it stopped working
• Object Compare but this didn’t work well I think because of the com object

I might just have to get my hands dirty and dig through the watch window but I thought I would see if anyone has any ideas. I am looking for a utility to do this with.

Here is a sample that I created using Reflection that maybe can help you:

private static void recurseAndFindProperty(Object obj) {
   foreach (PropertyInfo pi in obj.GetType().GetProperties()) {
       if ((pi.PropertyType.IsGenericType && pi.PropertyType.GetGenericTypeDefinition() == typeof(EntityCollection<>))) {
           IEnumerable collection = (IEnumerable)pi.GetValue(obj, null);

           foreach (object val in collection)
               recurseAndFindProperty(val);
       } else {
            if (pi.PropertyType != typeof(Descendant))
                if ((int)pi.GetValue(obj, null) == 1231241)
                    pi.SetValue(obj, 10, null)); // Change the value.
       }
   }
}
