Examples

The following code example demonstrates how to remove multiple model objects from the specified position.

using Appeon.ApiDoc.Models.School;
using System;
using PowerBuilder.Data;

namespace Appeon.ApiDoc.IModelStoreExamples
{
    public class RemoveRangeExample
    {
        private readonly SchoolContext _context;

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

        public void Example()
        {
            var courses = new ModelStore<Course>();

            // Retrieves data.
            courses.Retrieve(_context);

            // Shows the number of model objects in ModelStore before removed
            Console.WriteLine("Before Remove Count: {0}", courses.Count);

            // Removes two model objects starting from row 2
            courses.RemoveRange(1, 2);

            // Shows the number of model objects in ModelStore after removed
            Console.WriteLine("After Remove Count: {0}", courses.Count);

            /* This code example produces the following output:
            
             Before Remove Count: 12
             After Remove Count: 10
            */
