how to restrict setting a property of innerclass just from the outer class in c#

Question

I have the nub of the code like this:

public class OuterClass
{
    public static InnerClass GetInnerClass()
    {
        return new InnerClass() { MyProperty =

I'm afraid there is no access modifier which allows that. You can create IInnerClass interface and make the property readonly within interface declaration:

public class OuterClass
{
    public static IInnerClass GetInnerClass()
    {
        return new InnerClass() { MyProperty = 1 };
    }

    public interface IInnerClass
    {
        int MyProperty { get; }
    }

    private class InnerClass : IInnerClass
    {
        public int MyProperty { get; set; }
    }
}
