Question

I have a large class with many nested subclasses of different types as follows:

class BigFooClass
{
    // Classes
    Foo InnerFoo {get; set;}
    Bar InnerBar {get; set;}
    Oof InnerOof {get; set;}
    Rab InnerRab {get; set;}

    // Simple Properties
    Decimal OuterDecimal {get; set;}
    Long OuterLong {get; set;}
{

Each of these inner classes are defined as follows:

class Foo
{
   Decimal DecimalProp {get; set;}
   Long    LongProp {get; set;}
}
class Bar
{
   Decimal Decimal Prop {get; set;}
   Long    LongProp {get; set;}

} etc...

I want to get a list of ALL Decimal or Long properties together with their container types as follows:

BigFooClass.OuterDecimal is type of Decimal

BigFooClass.OuterLong is type of Long

Foo.OuterDecimal is type of Decimal

Foo.OuterLong is type of Long

Bar.OuterDecimal is type of Decimal

Bar.OuterLong is type of Long

I can get to the first level but cannot find how to reflect the type from a PropertyInfo, which may not be the correct way to do it.

Can anyone show me how to do it please?

Answer 1

Once you have the first level as a PropertyInfo, you’ll need to recurse down another level and check the properties within that type. You can do this by looking at the PropertyInfo.PropertyType member, and then using that type to call GetProperty/GetProperties and fetch the “second level” properties.
