Namespace: SnapObjects.Data

Assembly: SnapObjects.Data.dll

Syntax

public static IEnumerable<IModelEntry<TModel>> GetModelEntries<TModel>(
[NotNull]this IDataUnpacker packer,
[NotNull]string key,
[NotNull]MappingMethod mappingMethod) where TModel : class

Parameters

key System.String

The key specifying which element will be used to create the IEnumerable<IModelEntry<TModel>> object.

mappingMethod SnapObjects.Data.MappingMethod

A value of the MappingMethod enumerated datatype specifying the method for mapping columns.

Returns

System.Collections.Generic.IEnumerable<IModelEntry<TModel>>

Returns the newly created IEnumerable<IModelEntry<TModel>> object.

Remarks

If you are using a data format which has only data but no state for this element, the ModelState property of every IModelEntry object will be set to ModelState.NewModified.

Examples

The following code example gets the IModelEntry object in IDataUnPacker object according to the key and specifies the mapping method for importing data.

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

namespace Appeon.ApiDoc.IDataUnpackerExamples
{
    public class GetModelEntriesExample
    {
        private readonly SchoolContext _context;

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

        public void Example2(IDataUnpacker dataUnpacker)
        {
            // Gets the ModelEntries object according to the key value
            var students = dataUnpacker.GetModelEntries<Person>(
                "student", MappingMethod.Key);

            // Shows the students.
            foreach (var student in students)
            {
                Console.WriteLine("Model State: {0}",
                    student.ModelState);

                Console.WriteLine("First Name: {0}",
                    student.GetCurrentValue("FirstName"));
                Console.WriteLine("Last Name: {0}",
                    student.GetCurrentValue("LastName"));

                Console.WriteLine();
            }

            /* This code example produces the following output:
            
            Model State: NewModified
            First Name: Lena
            Last Name: Sherwood

            Model State: NewModified
            First Name: Davies
            Last Name: Adam
            */
        }
    }
}
