IDataStore.GetForUpdate<TModel>(int index) Method

.NET Standard 2.x

Obtains a TModel object for update according to the index number.

Namespace: DWNet.Data

Assembly: DWNet.Data.dll

Syntax

  public TModel GetForUpdate<TModel>(int index);

Parameters

index System.Int32

The zero-based index number of the row.

Returns

System.Int32

Returns the TModel object which contains the data for the row found.

Remarks

This method makes a shallow copy of the data, therefore, any changes made to this TModel will affect the data source. To make a deep copy of the data, refer to GetModel.

The index number starts from 0, which is consistent with C#.

Examples

The following code example demonstrates how to get data according to the row number.

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

namespace Appeon.ApiDoc.IDataStoreExamples
{
    public class GetForUpdateExample
    {
        private readonly SchoolContext _context;

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

        public void Example1()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            datastore.Retrieve();
			
			//Gets the first row of data for update.
            var department = datastore.GetForUpdate<D_Department>(0);

            Console.WriteLine("Department ID: {0},Department Name: {1}",
                department.Departmentid, department.Name);

            /*This code produces the following output:
             
            Department ID: 1;
            Department Name: Engineering
            */
        }
    }
}
