Question

I am writing a class which holds 90 integer variables. There are basically 10, but each has 3×3 attributes, making them 90. I’ll explain it further.

So the 10 variables I have are: v0, v1, v2, …, v9. Each of these has three different values, for city, county and state. Also, each of these has three different values for past, present and future.

So, a typical value would be: v3.City.Future or v7.State.Past or v8.County.Present.

I was thinking to implement a class, with 10 structs for each variable, then each of those struct has a three nested structs (for city, county and state) and each of those structs has three integer variables for past, present and future.

This is still in the conceptual phase. I tried to go with the above mentioned approach, but it is not working.

Here is the code snippet:

public class MyClass
{
    public MyVariable myvariable;
}

public struct MyVariable
{
    public struct National
    {
        public int Past { get; set; }
        public int Present { get; set; }
        public int Future { get; set; }
    }
    ...
}

Now when I instantiate the class and access the member (myclass.myvariable.National.Past), it does not get the member.

Answer 1

Here is the answer to this:

public struct PeriodVars
{
    public int Past { get; set; }
    public int Present { get; set; }
    public int Future { get; set; }
}

public struct VarStruct
{
    public PeriodVars City;
    public PeriodVars County;
    public PeriodVars State;
}

Now the class will be:

public class MyClass
{
    public VarStruct v0;
    public VarStruct v1;
    ...
}

Once I instantiate an object of the class, I can refer it to like this:

objMyClass.v0.City.Past = 111;
