How I can iterate data in structure

[Suliman via Digitalmars-d-learn]

void main()
{
	
	auto result = readconfig();

	foreach (_; result)
	{
		// I want to iterate result that I got from structure.
	}
}

auto readconfig()
{
	struct ConfigStruct
	{
		string key1;
		string key2;
	}

	ConfigStruct confstruct = ConfigStruct();
	confstruct.key1="Ivan";
	confstruct.key2="admin";

	return confstruct;

}
