What is internal set property in c#?

Question

I just came across an unknown concept of c# for me. Can anyone tell me what the purpose of an internal set property is? What is its use? I know internal keyword is used for work

Answer 1

Suppose you're designing an API for use by other programmers. Within this API, you have an object Foo which has a property Bar. You don't want the other programmers setting the value of Bar when they reference your assembly, but you have a need to set the value yourself from within your API. Simply declare the property as such:

public class Foo
{
   public string Bar { get; internal set; }
}
