Have the following structure with two arrays. It compiles OK but unable to access the array structures. Working in VC10. New to C#.

public struct Budget
{
public string budgetItem;
public double budget;
public double actual;
public double[] budgetAmount;
public string[] budgetNote;
}
const int ARRAY_LENGTH = 30;

Budget[] Budget_DB = new Budget[ARRAY_LENGTH];

What I have tried:

Have searched the web on this subject have not found anything helpful.

in my solution 3 I have a working version but it is not very efferent. How do I change solution 3 so that the budgetAmount and budgetNote are independent for each Budget[] index?

Here, a crude example of how you can do it:

C#

using System;
					
public class Program
{
	public static void Main()
	{
		Console.WriteLine("Hello World");
		
		const int ARRAY_LENGTH = 30;
		Budget[] Budget_DB = new Budget[ARRAY_LENGTH];
		
		var bAmount = new double[2];
		bAmount[0] = 1.0;
		bAmount[1] = 2.0;
		
		var bNote = new string[2];
		bNote[0] = "One";
		bNote[1] = "Two";
		
		Budget_DB[0] = new Budget(){
			budgetItem = "Test",
			budget = 100.0,
			actual = 200.0,
			budgetAmount = bAmount,
			budgetNote = bNote
		};
		
		Console.WriteLine(Budget_DB[0].budget);
		Console.WriteLine(Budget_DB[0].budgetAmount[0]);
		Console.WriteLine(Budget_DB[0].budgetNote[0]);
	}
	
	public struct Budget
	{
		public string budgetItem;
		public double budget;
		public double actual;
		public double[] budgetAmount;
		public string[] budgetNote;
	}
}

Output's

Hello World
100
1
One

You declared an array of Budget objects but have not assigned any objects to the array. You need to create a Budget object, populate it and then assign that to one of the members of the array and do this ARRAY_LENGTH times

I first set up my code to implement budgetAmount and budgetNote using single dimensional array. They issue is the budgetAmount and budgetNote values are seen in every Budget[] index. Would like it to just be 35 independent budgetAmount and budgetNote for each Budget[] index.

Id get the desired effect by creating 2 dimensional arrays, shown below, but now I carry they with every Budget[] index.

How can this be done using single dimensional arrays that are independent?

public struct Budget
{
public string budgetItem;
public double budget;
public double actual;
public double[,] budgetAmount;
public string[,] budgetNote;
}
const int ARRAY_LENGTH = 30;
Budget[] Budget_DB = new Budget[ARRAY_LENGTH]; /* Create unfilled array */

namespace Budget
{
public partial class Form1 : Form
{
public struct Budget
{
public string budgetItem;
public double budget;
public double actual;
public double[,] budgetAmount;
public string[,] budgetNote;
}
const int ARRAY_LENGTH = 30;
Budget[] Budget_DB = new Budget[ARRAY_LENGTH]; /* Create unfilled array */

public Form1()
{
InitializeComponent();

var bAmount = new double[30,35];
for (uint i = 0; bAmount.GetLength(0) < 30; i++)
{
for (int j = 0; bAmount.GetLength(1) < 35; j++)
{
bAmount[i, j] = 0.0;
}
}
//bAmount[0] = 1.0;
//bAmount[1] = 2.0;

/* Create space for budgetNote */
var bNote = new string[30,35];
for (uint i = 0; bNote.GetLength(0) < 30; i++)
{
for (int j = 0; bNote.GetLength(1) < 30; j++)
bNote[i,j] = "";
}
//bNote[0] = "One";
//bNote[1] = "Two";

/* Now create the data base */
for (uint index = 0; index <= 29; index++)
{
Budget_DB[index] = new Budget()
{
budgetItem = "",
budget = 0.0,
actual = 0.0,
budgetAmount = bAmount,
budgetNote = bNote
};
}
}
}
