How do I automatically display all properties of a class and their values in a string? [duplicate]

Question

Imagine a class with many public properties. For some reason, it is impossible to refactor this class into smaller subclasses.

I'd like to add a ToString override that returns something along the lines of:

 Property 1: Value of property 1\n Property 2: Value of property 2\n ... 

Is there a way to do this?

I think you can use a little reflection here. Take a look at Type.GetProperties().

public override string ToString() {     return GetType().GetProperties()         .Select(info => (info.Name, Value: info.GetValue(this, null) ?? "(null)"))         .Aggregate(             new StringBuilder(),             (sb, pair) => sb.AppendLine($"{pair.Name}: {pair.Value}"),             sb => sb.ToString()); }
