Examples

The following code example demonstrates how to get the minimum value for budget from the Department table.

using Appeon.ApiDoc.Models;
using DWNet.Data;
using System;

namespace Appeon.ApiDoc.IDataStore_GenericExamples
{
    public class MinExample
    {
        private readonly SchoolContext _context;

        public MinExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example3()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore<D_Department>(_context);

            datastore.Retrieve();

            // Gets the minimum value for budget.
            // The smallest budget is 120000.00
            double? MinBudget = datastore.Min(d => (double?)d.Budget);

            Console.WriteLine("Min Budget: {0}", MinBudget);

            /*This code produces the following output:
             
            Min Budget: 120000.0000
            */
