Developing a Budgeting and Expense App in C#

Creating a budgeting and expense tracking application involves managing financial data, performing calculations, and providing a user-friendly interface. In this example, we'll introduce the concept with a basic code snippet to manage expenses and calculate a budget.

Sample C# Code for Expense Tracking

Here's a basic example of C# code for managing expenses and calculating a budget:

using System;
using System.Collections.Generic;
class Expense
{
    public string Name { get; set; }
    public decimal Amount { get; set; }
}
class BudgetingApp
{
    private List<Expense> expenses = new List<Expense>();
    private decimal budget;
    public void AddExpense(Expense expense)
    {
        expenses.Add(expense);
    }
    public void SetBudget(decimal budgetAmount)
    {
        budget = budgetAmount;
    }
    public decimal CalculateRemainingBudget()
    {
        decimal totalExpenses = expenses.Sum(e => e.Amount);
        return budget - totalExpenses;
    }
}
class Program
{
    static void Main()
    {
        var budgetApp = new BudgetingApp();
        budgetApp.SetBudget(1000.0m);
        budgetApp.AddExpense(new Expense { Name = "Groceries", Amount = 200.0m });
        budgetApp.AddExpense(new Expense { Name = "Rent", Amount = 600.0m });
        decimal remainingBudget = budgetApp.CalculateRemainingBudget();
        Console.WriteLine("Budget: $" + budgetApp.CalculateRemainingBudget());
        Console.WriteLine("Remaining Budget: $" + remainingBudget);
    }
}

This code defines a `BudgetingApp` class that allows you to set a budget, add expenses, and calculate the remaining budget. In a complete application, you would create a user interface and potentially save data to a database.
